Hi @Ghosteu There are sound errors in the log: warning: Unknown DirectSound speaker configuration 8. Defaulting to Stereo. warning: SND: XACT3DApply failed. Invalid arg To fix this, please follow this guide: https://forum.faforever.com/topic/4084/solutions-for-snd-error-xact-invalid-arg-xact3dapply-failed If your game don't crash but freeze (sim stops, but UI is still working) Please try a game and don't let the AI play the UEF faction.
