Testing if VRR is active and working
I recently updated to fedora 40 and enabled the experimental setting to get VRR running. But I am an idiot who has been playing at frames rates between 30-60 on screens without VRR for almost all of my life so I can’t even know if VRR is actually working or not. Is there some rest I can run to see if VRR is functional¿? If not, which parts of the game should I concentrate to see the difference between VRR and no VRR¿?
There is a small utility app called VrrTest you can use to test it. I also use my monitor OSD utility to check if it’s really working.
You can also use NVIDIA’s Pendulum G-Sync demo in Wine/Proton. Despite the name it does work for any VRR capable display/GPU and I’ve used it to test VRR on AMD and Intel graphics on Linux. As much as I dislike NVIDIA, it’s a pretty decent VRR test tool.
I am on a immutable version of fedora(ublue-main) to be precise. Will the appimages work normally¿? I haven’t tried running an appimage since moving to using immutable distros
Does your display OSD feature a refresh rate counter?
