Hello Brutus,

when using "/affinity F" (including the quotes) I get a message about a file that cannot be found.
Client Version: 2025.2.1
java.io.IOException: Cannot run program "/affinity F" (in directory "C:\ProgramData\FAForever\bin"): CreateProcess error=2, The system cannot find the file specified

So i guess its trying but my format is wrong.

Hello,

When playing mission maps (alone or with people) i get a delay when any form of dialog comes up like another thread on this forum discusses. (https://forum.faforever.com/topic/8671/coop-missions-intermittent-lag)

For me it is fixed if i set the supreme commander's process affinity (CPU core selection) to only the first 4 cores.
I can start a command using [>start "" /affinity F "D:\Steam\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe"] as the command to run with this effect active, but that only runs the original game.

I want the [/affinity F] command to be added to when FaF starts the game, but this does not seem to work when i add it at the settings->forged Alliance Forever-> Command line format for Executable.

Is there another way i should be adding this information to apply it to the executable? Or can i combine it with other controls in that same settings to run the above command as an .bat file?

Thanks in advance,
Brogath

Hello, i have a similar issue with my new PC that i managed to resolve by going to my task manager after the game has started, go to the details tab and set the ' affinity' for supreme commander to only the first 4 cores of my cpu. This completely solves it for me, even though i do need to do it every new game.

I got he info from this steam forum thread: https://steamcommunity.com/app/9420/discussions/0/601895119916956285/?l=latam
