[SOLVED] Freesync causing stutters in older games

[Magmacream187]

When I play some older games, the games will stutter a lot. Even if I have it in borderless fullscreen and the fps capped it still does it. Examples are: surgeon simulator (the old one), portal 1, and other similar games. When I turn off freesync on my monitor or in amd settings the stuttering stops. Any help would be appreciated.
Note: some games will stutter a lot if I don't have them in borderless fullscreen such as cs:go. Just thought that would be a good thing to mention.

What frame rate are you trying to cap to? Try 143.

Try disable fullscreen optimisation for the game's exe under compatibility.

Another thing to try is with fps capped to 143, have vsync in Adrenaline set to application control and use the game's vsync. Might help with the stutters. Input lag shouldn't be present but let me know if it is.
