Turned off ReBar & tried mangohud fps limiter, still no dice. Noticeable hitching is very annoying. It's definitely the problem with optimization of Forza Horizon 4 for Steam. Nothing changed compared to when I played the initial Steam version back in 2021.
I guess I will have to resort to Windows for this game.
okay so im starting to think the gnome version just has issues the other version doesnt have. i closed steam for a second to do something and now after opening it i can no longer use my trackpad
