Proton 4.2-9 has just been pushed. This small update specifically fixes issues with online functionality in some games, such as Soulcalibur VI, that were affected by the recent 4.2-8 update. No other changes were included.
Proton version 4.2-8 is out today and includes a few small changes. Most notably is a fix for the new metroidvania Bloodstained: Ritual of the Night. Early reports on ProtonDB seem hit-or-miss so far, but the game has been getting very positive reviews so it could be worth trying now.
- Fixes for games which embed web browsers using the Steam client. For example, Football Manager 2019.
- Fix an issue with Bloodstained: Ritual of the Night and other titles crashing with an error dialog on exit.
- Upgrade wine-mono to 4.9.0, which includes winforms support. This may help some game launchers.
- Various window management and alt-tab fixes.
- Fix for controllers losing force feedback when removed and re-added.
DXVK, the Direct3D 10/11 to Vulkan translation layer for Wine, also received a few bug fixes. This includes the fix made by Valve for Unreal Engine 4 games like Bloodstained. However, the rest of these improvements have not made it into the Proton branch of DXVK yet.
- Fixed bug that would cause some Unreal Engine 4 games to show error messages upon exit
- Fixed regression which would break texture loading in World of Warships and potentially other games
- More minor CPU overhead optimizations
- Implemented timestamp disjoint queries properly to make measuring time on the GPU more robust.
- Improved memory allocation behaviour under memory pressure. This may in some situations improve performance on lower-end Nvidia GPUs.
- Improved staging buffer allocation behaviour to limit the amount of memory that is permanently reserved for resource uploads.
