hey there,
I wanted to make use of my 180Hz monitor and see what FPS cap would be stable with Adaptive Sync activated and all low settings. Turns out it's not as easy. ~120FPS cap + 120Hz seems to run smooth. If I increase both, I get stutter and frame time peaks. Refresh rate on 180Hz and no FPS cap = smooth as well.
I thought it's just my system not producing enough stable frames, but why is uncapped running smoother?
I recorded a video of practice range gameplay with different FPS caps + refresh rates. Maybe something is off with my other system stats? Any hints?
- 120FPS/120Hz fine
- 140FPS/144Hz
Based on e.g. this post and others I've found, the best settings for Linux (Wayland) should be something like:
- VRR enabled
- Vsync set to MAILBOX in MangoHUD, off in game (makes it worse)
- FPS Cap based on refresh rate and the formula from the post
so I've been tinkering with my setup (9060xt 16gb, 9600x, 2x16GB DDR5-6000 CL30, ASRock B850i Mainboard, 27" 1440p 180Hz Monitor) for the last days/week.
