The community-maintained GE-Proton compatibility layer has another small release out for Linux desktop / Steam Deck with GE-Proton 8-23 being released November 8th.
Reminder: this is the version of Proton not supported by Valve. It may have issues at times the official Proton does not. However, it also at times pulls in fixes a bit quicker and can do things sometimes that Valve cannot do. To sum up: use it if you need it for specific games, otherwise sticking with the official Proton is the best idea. More about Proton can be found in my Proton beginner's guide.
Here's what's changed:
- added reverts for vrclient to allow VRChat to work again (pending proper fix from valve: ValveSoftware#1199 (comment))
- the gstreamer plugin build options have been re-worked. Rather than enabling everything under the sun, we've now manually enabled each option that was reported as enabled in previous builds, and disabled the rest. This was done to more align with what Valve is doing and to allow a clearer picture of what may be missing from Valve's proton rather than taking wild guesses. Doing this may allow Valve a better idea of additional codecs/filters that might be missing in case they need and/or can be enabled. (thanks loathingKernel for taking the time to do this)
- dxvk updated to latest git
- vkd3d-proton updated to latest git
- wine updated to latest bleeding edge
Changelog can be found here.
