Right after starting the game, my friend causes a desync in a whole lobby. it happens every second game strangely, the second half being played without said issue, and we cannot find why. We reinstalled FA and FAF, but the issue persists. I attached log files, ice-adapter.log and game_22714335.log and you can see this happening in replays, for example: https://replay.faforever.com/22714335 If anyone could tell the reason for desyncs and how to fix them? I would gladly give more info if needed. Thanks!
Desync at the start of the game
Immediate desyncs, as soon as the game has started, are usually an indication of a map related issue.
@pipidon1337 Is the attached game_22714335.log file yours or your friend's? If it's yours, please also attach the same file from your friend so they can be compared.
Since this is a vanilla SCFA map, which version of vanilla SCFA do they have; Steam, GOG, CD/DVD?
In the case of Steam or GOG, please have them verify the game files from the respective Steam or GOG programs.
We both have Steam version. The logs I gave are RazorRunner's - the person having issues. I am attaching the same game log file from my side: game_22714335.log
It cannot be a map issue as it happens on all maps as long as RazerRunner is a player. He is doing a steam verifications right now. I will write back on the result.
We haven't experienced any desyncs in 3 games now. BTW, can screen resolution and UI scale cause problems in-game? Because other that desyncs, sometimes his screen just goes black and whole PC reboots. That is a different matter though 
we speculate it is because he has 4k screen. as if he lowers the resolution, game works fine.
Desyncs are almost always caused by different source files. This can be from:
- Maps (when people tweak their local maps)
- Game files (can happen when a release just occured)
- Mod files (when people tweak their local mods)
UI related changes can not cause a desync.
