Summary of issues on the top of my head that still exist:
- Random black screens when playing intensive games, sometimes resulting in a partial GPU driver crash. It is sometimes possible to switch to a TTY, but attempting to switch back to a graphical session will crash the driver for good.
- When a display goes to sleep or is turned on, it may not receive a signal from the driver. Unplugging and replugging the display cable from the GPU will eventually fix this.
- Rebooting may result in no BIOS display signal. Only unplugging and replugging the monitor back in seems to fix this.
- Desktop memory usage is excessively high(over 2GB sometimes).
- A large amount of GPU Memory is unaccounted for in
nvidia-smi/ NVML. - Applications crash when VRAM is full.
- Shared RAM under Linux seems broken. It’s almost like there is an incredibly small amount(256MB) and once that’s gone things start crashing.
- DLSS3 / DLSS4 / Smooth Motion is broken. It universally lowers FPS and can cause massive input lag and micro stuttering.
- Gnome-shell / GDM can freeze on login from a fresh boot. Switching to a TTY and relogging in works around this.
- Ray Tracing is broken on a lot of games, resulting in an XID 109 or some other error.
- Some games have XID 13 errors like Metro Exodus EE in the main menu.
- Some games show DLSS upscaling options but no frame generation(GTA 5: Enhanced and Portal 2: RTX). Maybe a Proton issue?
- Dragging the HDR slider under Gnome can cause a driver crash.
- DX12 games have a massive performance penalty.
