Hi everyone!
I recently installed bazzite-gnome-nvidia-open:stable (up to date as of July 24th 2025) on my PC and need some help with VRR configuration.
My Setup:
- CPU: AMD 7800X3D (iGPU disabled in BIOS)
- GPU: RTX 3090
- Kernel: Linux 6.15.6-105.bazzite.fc42.x86_64
- Display: 3440×1440@180Hz connected via DisplayPort
- Launching games through Steam in desktop mode
Issue:
I’m having trouble getting VRR (Variable Refresh Rate) to work properly—games aren’t syncing their framerate with my monitor’s refresh rate.
Questions:
- VRR Compatibility: Is VRR supported on my hardware configuration? Are there any known limitations I should be aware of?
- V-Sync Settings: Should V-Sync be enabled or disabled in games for VRR to function correctly?
- GNOME VRR Integration: How does GNOME’s VRR feature interact with gaming sessions?
- Does it only work with fullscreen games?
- Is Gamescope required?
- Must VRR be enabled in system settings for games to utilize it?
- Launch Options: When should I use Steam launch options like
gamescope -f %command%?
- World War Z won’t start without this parameter, while other games run fine
- How does this affect the gaming experience and VRR functionality?
Any guidance or resources would be greatly appreciated. Thanks in advance!
