You have to limit your FPS to 60 or 75 FPS, else your CPU will cause stuttering. Because the game is a single threaded game that doesn’t take advantage of multithreading. At 60 FPS all stuttering is gone for me, but i rather play with 75 FPS and 97% of all stuttering gone. 15 more FPS still feels a bit smoother than horrible 60 FPS. We live in the year 2024 we shouldn’t have to play games at fixed 60 FPS anymore. It’s ridiculous how bad the CPU performance is in this game. In Forza Horizon 4 and 5 i can play with up to 120 FPS in 2160p and get ZERO stuttering. But in the FM 2023 i start to get stuttering at everyting above 75 FPS.
I been ranting about this multiple times already.
