Now that the testing is open for Proton 9, Valve have now updated Proton Experimental to move over to Proton 9 along with a bunch of extra game fixes for Steam Deck / Linux.
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 But I’ve come to the conclusion that a lot of the posts there use outdated or simply false launch options.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.
