    well yes,

    1. this is more optimized, lower consumption of resources than Game companion and
    2. this allows to execute our optimization of FA itself.

        @tatsu said in [Guide] : fake-fullscreen and optimisation:

        There are multiple versions of the script depending on your monitor setup, and whether you just want the windowed fullscreen, the optimization, or both.

        This makes it seem like you shouldn't need fake fullscreen for the optimisation. As it is, I couldn't get the fake fullscreen to work this way for some reason (probably user error) so I will just switch back to what I was doing before I guess.

          Just so no one has to look for it, from the prior thread, here is the script given if you want to use AHK for optimization, without using it for Fake Fullscreen. There are other examples of scripts people used in the prior thread (https://forums.faforever.com/viewtopic.php?f=2&t=9778)

          #NoEnv
          SendMode Input
          SetWorkingDir %A_ScriptDir%
          #Persistent
          
          procName := "ForgedAlliance.exe"
          SetTimer, CheckProc, 2000
          Return
          
          
          CheckProc:
              If (!ProcessExist(procName))
                  Return
          
              WinGet Style, Style, % "ahk_exe " procName
              If (Style & 0xC40000)
              {
          Run, %comspec% /c process -a forgedalliance.exe 111111111110    ;remember to edit this to fit you thread count!!
          Run, %comspec% /c process -p forgedalliance.exe high
              }
              Return
          
          ProcessExist(exeName)
          {
             Process, Exist, %exeName%
             return ERRORLEVEL
          }
          
          return
          

          (And remember to edit the thread count where the comment in the code indicates, e.g. 1110 for 4 logical cores, 11111110 for 8 cores)

              yeah I had that too.

              check the spacing.

              it's space sensitive for where it begins and ends the loops.
              mine looks like this :

                  no.

                  I don't think so.

                  I gave up but if you find a way let me know!

                      Made anower variant of AHK script.
                      Using Win 10, AutoHotkey, Steam version of game and Downlord's FAF Client.
                      For some reason Steam runs "SupremeCommander.exe", FAF Client runs "ForgedAlliance.exe".

                      I made some manipulations to make AHK script

                      • stop or pause by itself if game haven't started after 2 minutes or right after script done all things,

                      • do things only once on each game start,

                      • do nothing then nothing is needed and also

                      • run singleplayer from descktop shortcut made by Steam,

                      • run multyplayer from descktop shortcut for Downlord's FAF Client.

                      Lets start from Steam descktop sortcut:
                      Just right click game shortcut , go to Properties and change URL (I had steam://rungameid/9420, we will start it in script) and insert full file path to your script, Save. Old URL insert into script.
                      To check it, simply open sortcut in any notepad you have. You will see somethig like that:
                      File "Supreme Commander Forged Alliance.url":

                      [{000214A0-0000-0000-C000-000000000046}]
                      Prop3=19,9
                      [InternetShortcut]
                      IDList=
                      IconIndex=0
                      URL=file:///D:/Program%20Files/FAF%20borderleess%20fullscreen%20window.ahk
                      IconFile=D:\Steam\steam\games\540979be595a41206b56a2e427c29dce1c212ad2.ico
                      HotKey=0
                      

                      Note: just Ctrl+C -> Ctrl+V full file path, Windows will add "file:///...%20..." staff by itself if done in Properties.

                      Next is doing the same for FAF Client:
                      Right click this time Downlord's FAF Client sortcut (it is standard *.lnk, no url staff) go to Properties and change Object path from "D:\Program Files\Downlord's FAF Client\downlords-faf-client.exe" to "D:\Program Files\Downlord's FAF Client\FAF borderleess.ahk". Old Object run in script.

                      So, it is time for scripts!

                      Scrip file "FAF borderleess fullscreen window.ahk" in "D:/Program Files/" directory for singleplayer:

                      #NoEnv
                      SendMode Input
                      SetWorkingDir %A_ScriptDir%
                      #Persistent
                      
                      Run, steam://rungameid/9420
                      procName := "SupremeCommander.exe"
                      
                      Process, Wait, %procName%, 120 ; Waits for process to start, no more then 120 seconds
                      NewPID := ErrorLevel
                      if not NewPID
                      {
                          MsgBox The specified process did not appear.
                          ExitApp ; Stop this script
                      }
                      
                      SetTimer, CheckProc, 2000
                      return
                      
                      CheckProc:
                          if (!ProcessExist(procName))
                              return
                           
                          WinGet Style, Style, % "ahk_exe " procName
                          if (Style & 0xC40000)
                          {
                              WinSet, Style, -0xC40000, % "ahk_exe " procName ; remove the titlebar and border(s)
                              WinMove, % "ahk_exe " procName , , 0, 0, 1920, 1080 ; move the window to 0,0 and resize it to fit across 1 or 2 monitors.
                              WinMaximize, % "ahk_exe " procName
                              WinRestore, % "ahk_exe " procName
                      
                              ; set High priority and cores affinity 
                              Process, Priority, %procName%, H
                              ProcessHandle := DllCall("OpenProcess", "UInt", 0x1F0FFF, "Int", false, "UInt", NewPID)
                              DllCall("SetProcessAffinityMask", "UInt", ProcessHandle, "UInt", 14 ) ; 1110x2 = 14x10 CPU 0 unchecked, CPU 1-3 checked
                              DllCall("CloseHandle", "UInt", ProcessHandle)
                      
                              ExitApp  ; Stop this script
                          }
                      return
                      
                      ProcessExist(exeName)
                      {
                         Process, Exist, %exeName%
                         return !!ERRORLEVEL
                      }
                      return
                      

                      This one starts before singleplayer, calls Steam to run the game, waits for game, does borderleess fullscreen and optimisation and stops right after that. No script running while you are playing.

                      Scrip file "FAF borderleess.ahk" in "D:\Program Files\Downlord's FAF Client" directory for multyplayer:

                      #NoEnv
                      SendMode Input
                      SetWorkingDir %A_ScriptDir%
                      #Persistent
                      
                      Run, downlords-faf-client.exe
                      
                      procName := "ForgedAlliance.exe"
                      procNameClient := "downlords-faf-client.exe"
                      
                      Process, Wait, %procNameClient%, 120 ; Waits for process to start, no more then 120 seconds
                      NewPID := ErrorLevel
                      if not NewPID
                      {
                          MsgBox The specified process did not appear.
                          ExitApp ; Stop this script
                      }
                      
                      SetTimer, CheckProc, 2000
                      
                      ; Stop then FAF Client stoped
                      Process, WaitClose, %procNameClient%
                      ExitApp
                      
                      CheckProc:
                          if (!ProcessExist(procName))
                              return
                      
                          WinGet Style, Style, % "ahk_exe " procName
                          if (Style & 0xC40000)
                          {
                              WinSet, Style, -0xC40000, % "ahk_exe " procName ; remove the titlebar and border(s)
                              WinMove, % "ahk_exe " procName , , 0, 0, 1920, 1080 ; move the window to 0,0 and resize it to fit across 1 or 2 monitors.
                              WinMaximize, % "ahk_exe " procName
                              WinRestore, % "ahk_exe " procName
                      
                              ; set High priority and cores affinity 
                              Process, Priority, %procName%, H
                              NewPID := ErrorLevel
                              ProcessHandle := DllCall("OpenProcess", "UInt", 0x1F0FFF, "Int", false, "UInt", NewPID)
                              DllCall("SetProcessAffinityMask", "UInt", ProcessHandle, "UInt", 14 ) ; 1110x2 = 14x10 CPU 0 unchecked, CPU 1-3 checked
                              DllCall("CloseHandle", "UInt", ProcessHandle)
                      
                              Process, WaitClose, %procName%
                          }
                      return
                      
                      ProcessExist(exeName)
                      {
                         Process, Exist, %exeName%
                         return !!ERRORLEVEL
                      }
                      return
                      

                      This starts before FAF Client and waits for FAF Client to run the game. Script is checking for game in loop every 2 seconds. On every game start it does borderleess fullscreen and optimisation BUT does NOT stop after that. Script pauses the loop while you are playing, but is still running while doing nothing. Then the game is over script will resume the loop to catch your next game start. Once you stops FAF Client, sript will stop automaticully.

                      Now :

                      • sortcurts will run AHK scripts,

                      • scripts will run game in Steam or run FAF Client,

                      • scripts do nothing while you are in game

                      • you don't need to stop scripts and

                      • you can hide script file anywhere (well, for FAF Client better keep it in client's dir, maybe becase of ' in directory name).

                      • Oh, and you need only AutoHotkey for this to work.

                      If all worked fine you will see in task manager high priority and unchecked first core (CPU 0) affinity for game process, "fake fullscreen mode" in game and no Alt+Tab issues.

                      Note:
                      In case your taskbar don't want to hide at all (rarely happens when very actively using other soft at game start, so I don't fix it) you may add hotkey or auto hiding like this:

                      Process, Wait, %procName%, 120
                      NewPID := ErrorLevel
                      if not NewPID
                      {
                          MsgBox The specified process did not appear.
                          ExitApp
                      }
                      ; hide taskbar on process start
                      HideShowTaskbar(true)
                      
                      ; here do anythig like SetTimer, CheckProc, 2000
                      
                      Process, WaitClose, %procName%
                      ; show taskbar on process stop and stop this script

                      ; this should be in the end of the script, nothing else worked otherwise...

                          Not that well it seems)
                          Thanks for you comment I reread post and found one significant error:
                          It seem I Copy-pasted not the latest version, multipleer script neend one extra line to make it pause the loop
                          " Process, WaitClose, %procName%" in the end of "if" section. Without this line script do not pause the loop...

                            One more error fix: in "NewPID" remain procces ID of FAF Client, not the game, so process affinity was set for FAF Client, not for game 😕
                            Fixed by adding "NewPID := ErrorLevel" after setting high priority:

                            ; set High priority and cores affinity 
                                    Process, Priority, %procName%, H
                                    NewPID := ErrorLevel
                                    ProcessHandle := DllCall("OpenProcess", "UInt", 0x1F0FFF, "Int", false, "UInt", NewPID)
                                    DllCall("SetProcessAffinityMask", "UInt", ProcessHandle, "UInt", 14 ) ; 1110x2 = 14x10 CPU 0 unchecked, CPU 1-3 checked
                                    DllCall("CloseHandle", "UInt", ProcessHandle)
                                    
                                    Process, WaitClose, %procName%
                                }
                            

                            Hope it was last one...

                                @io_nox Thanks for the script revision (also thanks to @tatsu for the original). I do have a couple questions.

                                1. How would I revise the line for changing the affinity for 16 logical processors?

                                2. To use this for the LOUD mod which uses the exe from the base SCFA install (Steam for me) but points to its own init file for loading, would I just need to replace "steam://rungameid/9420" in the script with the contents of the Target of the LOUD desktop shortcut ("F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe" /log "..\logs\Loud.log" /init "..\LOUD\bin\LoudDataPath.lua")?

                                Any help you can provide is appreciated.

                                Thanks.

                                  1. well I type 1s and I count to 15 with every 1 and then I type a 0 :

                                  1111111111111110

                                  do you mean with the IO_Nox method? no idea. maybe it does it automatically with his code?

                                  1. Again I don't know what script you're talking about. if it's mine then you just need to detect whatever exe so the name would be "SupremeCommander.exe"

                                    affinity for 16 logical processors

                                    as @tatsu said 15 ones and last zero may work, by on my 4 threads in win 10 number 1110 have not worked and 14 worked well. So you can try 1111111111111110 and if it is not working here some counting systems math staf:

                                    • for me 4 threads, so - 1110 in binary is 0 * 2^0 + 1 * 2^1 + 1 * 2^2 + 1 * 2^3 = 0 * 1 + 1 * 2 + 1 * 4 + 1 * 8 = 14 in decimal (normaly used in live)
                                    • for your 16 threads: 1111111111111110 binary is 65534 in decimal (from some random converter in goole search first page) 3a022b3d-6273-410f-b842-9eb21f045a27-image.png
                                      so you will have:
                                    DllCall("SetProcessAffinityMask", "UInt", ProcessHandle, "UInt", 65534 )
                                    

                                    It works like you are setting yes/no flags for each CPU: 0 to disable and 1 to anable, and combines result in 1 number. Flag f for CPU-N will be f * 2^N and sum of all flags is your number. Why fist CPU-0 is always last right? It's because in numbers power order is reverted - similar way 65534 in decimal is 4 * 10^0 + 3 * 10^1 + 5 * 10^2 + 5 * 10^3 + 6 * 10^4

                                    replace "steam://rungameid/9420" in the script with the contents of the Target of the LOUD desktop shortcut ("F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe" /log "..\logs\Loud.log" /init "..\LOUD\bin\LoudDataPath.lua")?

                                    Should work I think, thecnicaly it is just link or path to executable file. Where is no tricky symbols in path ""F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe"
                                    but I don't know if " /log "..\logs\Loud.log" /init "..\LOUD\bin\LoudDataPath.lua"" additional part will work properly but usually it should work.

                                    Based on this https://www.autohotkey.com/docs/commands/Run.htm#Remarks
                                    and this
                                    https://autohotkey.com/board/topic/9603-run-exe-with-parameters/

                                    Try somethig like

                                    Run, "F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe" /log "..\logs\Loud.log" /init "..\LOUD\bin\LoudDataPath.lua"
                                    

                                    or

                                    Run, "F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe" log "..\logs\Loud.log"  init "..\LOUD\bin\LoudDataPath.lua"
                                    

                                    or

                                    Run %ComSpec% /c ""F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe" /log "..\logs\Loud.log" /init "..\LOUD\bin\LoudDataPath.lua""
                                    

                                    or anover variation.

                                      faster way to get magical number for N threads is
                                      2^N - 2

                                      • 2 threads: 4 - 2 = 2
                                      • 4 threads: 16 - 2 = 14
                                      • 6 threads: 64 - 2 = 62
                                      • 8 threads: 256 - 2 = 254
                                      • 10 threads: 1024 - 2 = 1022
                                      • 12 threads: 4096 - 2 = 4094
                                      • 14 threads: 16384 - 2 = 16382
                                      • 16 threads: 65536 - 2 = 65534
                                        why: 2^N - 1 in binary will be number of N ones (111...111) we need number lower by 1, so (2^N - 1) - 1 is 11...110

                                        path := "C:\Program Files\Notepad++\notepad++.exe --help"
                                        Run, %path%
                                        

                                        worked well so may be your mod will run same way.

                                        may be I will soon update script one more time to use 1 script for both singleplayer and faf....

                                          New script revision

                                          I tried to localize all variable you need to set manually in the begining.
                                          Threads count is now AHK work!
                                          This is 2 in 1 script.
                                          (May be one day I will do 3 in 1 for any map editor... but now I think it will work if you change all FAF Client staff to your Map Editor staff)

                                          My steam shortcut simply runs script

                                          [{000214A0-0000-0000-C000-000000000046}]
                                          Prop3=19,9
                                          [InternetShortcut]

                                          URL=file:///D:/Program%20Files/SC%20FAF%20borderleess.ahk

                                          My faf client shortcut runs SAME script with command line parameter faf
                                          Object value is:
                                          "D:\Program Files\SC FAF borderleess.ahk" faf

                                          ![faf shortcut Properties img](a181882b-4a64-4edf-8849-966746c95b13-image.png image url)

                                          One Script to run them all!

                                          if I

                                          • run it with command line parameter faf (no matter file name) or
                                          • rename script file into FAF borderleess.ahk
                                            it will run FAF Client
                                          • else it will run game from steam (if file name NOT starts with "faf").

                                          Note:
                                          If file name starts from FAF it will allways run FAF, so you can have 2 copies like "faf script.ahk" and "sc script.ahk" to run game if you don't want to use command line parameter:

                                          • "faf script.ahk" will run only multiplayer, and
                                          • "sc script.ahk" will run singleplayer by default and multiplayer if called with parameter faf

                                          Problem:
                                          "D:\Program Files\Downlord's FAF Client\downlords-faf-client.exe" is not starting client... but "downlords-faf-client.exe" works fine (if script is in faf client's dir)...
                                          so i am calling this script from fake faf shortcut to call another faf client shortcut from it...
                                          Interesting thing is that AHK tells me "File exists" if I'm giving it my full path... but can't run it...

                                          About runnig game with command line args:
                                          AHK can do it, but some trying, AHK docks reading and googlesearching may be needed. I left some tips in code as comments, maybe it will be helpfull.
