I've been hoping to get Elden Ring up and running before the DLC comes out, but I haven't had much luck so far. I am a newbie to Linux, currently running Debian 12 w/ GNOME, Ryzen 9 3900X, GTX 1080 Ti.
I have tried every proton version and plenty of suggested launch options with slightly varying levels of "success", but the best I manage to get is Proton GE with no launch options and the game launches, flashes black, then white and then crashes, the whole time with the game's custom cursor. Most other combinations get me a black screen before launch, no launch, or nothing (but steam says its running for a minute).
I believe my video drivers are all up to date, but I am a newbie, like I said, so I'm not confident I didn't miss something. Has anyone else been running into this? Any help would be greatly appreciated.
Update: I installed the proprietary Nvidia drivers and now only get a black screen or frozen terminal when I launch my PC. I'm currently in recovery mode and attempting to follow troubleshooting guides with no luck. "ERROR: The control display is undefined; please run 'nvidia-settings --help' for usage information." Is one of the errors I keep getting, but I only get part of the help dialogue, the rest is cut off. nvidia-smi just froze everything. Would it be a good idea to just go back to my installation media?
Are you running it with EasyAntiCheat enabled? When I had an issue with the same behavior (white screen, custom cursor, then crash) EAC wasn't initializing properly. If i recall correctly, I reinstalled the proton EAC runtime on Steam to fix it.
Also as another commenter said, don't expect great performance with that GPU. While I was still using a 1080ti at Elden Ring's launch I got around 35-45fps at 1440p, while easily hitting 60 on Windows.
