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 But I’ve come to the conclusion that a lot of the posts there use outdated or simply false launch options.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!
