It is not necessarily worth it as PES will stutter if you try and push the FPS too high anyway.
2019 was a stuttering mess at 140, then I saw that it’s best to just set the FPS to application controlled in the nvidia control panel and low and behold, stuttering solved at a stead 100 fps.
Could you explain how did you set 100fps ? Any tool needed ?
Why Fraps shows only 72fps vsync on and 80-90 off ?
