yea it exists, if u have amd gpu - use radeon chill, and if nvidia make it just like on amd. (idk whats soft on nvidia i jus have amd)

also with riva tuner you can limit fps with different settings like set or add 30 fps 60 fps yk (watch guide on yt)

Is there any allowed asi loader? I want to run any%, but I need fixed fps and resolution, but I donno how to make it without any mods.
