I just learned that PROTON_ENABLE_NVAPI=1 to enable DLSS got changed to PROTON_FORCE_NVAPI=1 in Proton 9.0 (including Proton Experimental). Just in case this helps someone in the future.
On another note: Feel free to let me know if you’ve got a good way to keep up with necessary/useful launch options. I’ve simply been having a look at what people use on ProtonDB. But I’ve come to the conclusion that a lot of the posts there use outdated or simply false launch options.
The list in the GitHub is the reference as far as I know https://github.com/ValveSoftware/Proton?tab=readme-ov-file#runtime-config-options
But the NVAPI change is not listed yet.

I can’t believe how well Helldiver’s 2 has worked for me. My friend on Windows has crashed all the time and the anti-cheat is super intrusive. But on Linux, literally no problems. No launch flags or anything, just click play in Steam.
Definitely a highlight of this timeline!
Can you mention what your specs are and whatnot? I’ve been getting abrupt random crashes over and over from it, and literally exclusively from it from what I can tell.
EDIT: Figured it out. You need to run the game on DirectX 11 instead of 12 for certain cards. Insert " %command% --use-d3d11 " into the game’s launch options in steam. Game runs great now.
Putting this as a top thread as a PSA.
If the game is running smoothly but you’re having random crashes, try this.
