Game mode FPS limiter inconsistent and overshooting set value #4545
Description
Describe the bug
While in Bazzite Deck Gaming mode, the built in frame rate limiter in the Quick Access Menu has been inconsistent. With my 360hz monitor with VRR on, I try setting the FPS limiter to 355 and the performance overlay still shows the fps as 360 fps. It's not until I limit to around 343 fps when the limiter seems to kick in, but even then it will often overshoot the set fps cap when actively playing a game (Silksong & Tunic in my case). When setting the FPS limiter to 320, the fps would go over 320.
What did you expect to happen?
I expected the fps limit to limit the fps similar to RTSS on Windows.
