In general, any changes that can go to upstream wine, should go upstream first, and https://gitlab.winehq.org/wine/wine/-/wikis/Developer-FAQ#can-i-contribute-code-generated-by-a-large-language-model-llm-tool should be taken into consideration while doing that. Over time, we want the difference between upstream wine and Proton to shrink, so that Proton remains maintainable.

    Presumably, now that SteamOS 3.9 is stable and uses the 7.2 kernel, a lot more people should be running into this problem.

    There is a new build: `proton-je-11.0-20261001-3`, the patches had a regression which showed up when I played Foundry for a little bit. Grab the new build, or update your own locally patched proton: https://github.com/je...

    Just wanted to say Thank you, the fix absolutely fixed the SM2 crashing bug for me. You guys are doing god's work and for the emperor! :)

    @Erfboom thanks! Yeah, any feedback on any games is great, even if the feedback is, no perceivable effect.

    @jegglest I can also help with testing. I added your patches to proton GE lastest, compiled, and ran briefly with Control Resonance and it did not cure my crash on an rtx3080 that pyroveil fixes which most likely means i...

    @defaultuser321 yes, that would be great! I'm quite confident the patches fix space marine 2. What I'm most interested in is if anyone can find a game that the patches break. proton-je now has FSR 4 support. @Jpokul it w...
