Additionally, half-a-dozen regressions were fixed from Proton 8 – controller hotplugging should now properly work, and a few fixes made it in for Resident Evil 4 and Have a Nice Death.

VKD3D-Proton was updated to 2.10, which “rolls up a ton of bug fixes, game and driver workarounds, and other improvements.” DXVK was updated to 2.3.
