As usual for a new release of GE-Proton, GE-Proton 8-28 came with some issues, and so some hotfixes are available bringing it up to GE-Proton version 8-30.
This is why I usually remind people to only use GE-Proton when they actually need it for specific games, because it sees far less testing than the official Proton from Valve. It's good when you need it though but generally best to stick to what's official for less unexpected issues.
For GE-Proton 8-29:
- hotfix: updated proton bleeding edge to include tekken 8 online match disconnect fix
- updated vkd3d-proton
- fix issue with drive_c symlink during prefix creation when using ulwgl (it's now possible to run scripted game installations using ulwgl and proton-ge)
And then GE-Proton 8-30:
- fixed EAC not getting loaded. During my ULWGL changes I accidentally made it so steam games werent running using steam.exe inside the prefix... which of course broke EAC games. The code snippet involved is needed so that non-steam games don't try to run using steam.exe and thus dont create the Steam_API error. woops. fixed now.
