Maybe it will help someone. I launched the game after today's update. Performance and audio issues. 1. I have made a copy of this folder. C:\Users\<username>\Documents\My Games\TrainSimWorld2 2. I deleted this folder ^^ 3. I have restored my profile from a previously saved copy. C: \Users\<username>\Documents\My Games\TrainSimWorld2\Saved\SaveGames It helped. Works smoothly now. As for modifying engine.ini, I was only using 'motion blur off'.
