I’m using a 3080 under Plasma, and I thought 555 was doing great, since I could finally use electron apps without input lag or flickers. I didn’t bother much with gaming since VRR does’t work if the NVIDIA GPU has more than one display enabled on it (you can use a second GPU or an iGPU to workaround that). I decided to give it a go anyways, wrote a script that turns off my second screen when I open a game and enables it again when it closes.
Unfortunately, 555 was unusable for me. After a short while, Xwayland would crash and either Steam and the game would instantly close or my entire system would freeze, requiring a reboot. I thought this was an issue with Steam, so after some extensive log collection, I opened an issue on their GitHub and shortly after a dev analysed them and told me that my issue was likely due to explicit sync, and asked me to downgrade to a pre-explicit sync driver.
I went back to 550.90 and my crashes stopped completely. It also stopped a coredump spam of glsdisplay by Steam, and also fixed a power draw bug in which my GPU would never go below 100W, even on idle. I never had issues with games flickering previously, and I still don’t have it now, and I was able to fix the electron apps flicker and input lag by setting ELECTRON_OZONE_PLATFORM_HINT=wayland
on my env, so for now I’m sticking to 550.
I also opened a bug report on NVIDIA’s forums and I’m waiting for any input.
I had a dualsense before, bought it thinking of those features. Turns out that a few games had support for it on PC, and most were shooters so I wouldn’t play using a controller.
The battery was abysmal too, it would barely last 4 hours. I’ve heard on some places that it was due to the touchpad being polled for input all the time, draining the battery.
Moved over to a 8bitdo ultimate Bluetooth with Hall sticks and couldn’t be happier
