The Vulkan-based implementation of D3D9, D3D10 and D3D11 for Linux / Wine named DXVK (used with Proton) has a 1.9.4 version release, plus it appears that Proton 7.0 is closing in. More info on Steam Play Proton on our dedicated page.
DXVK 1.9.4 is quite a small one simply preparing for the next Proton release, here's what's new:
- Fixed an issue that would cause VRAM to not be utilized on RBAR-enabled Nvidia GPUs if the
dxvk.shrinkNvidiaHvvHeapoption is enabled (#2438).
- Enabled strict D3D9 float emulation by default on future versions of RADV. This may improve both accuracy and GPU-bound performance (PR #2448).
- Improved memory allocation behaviour. This may reduce memory usage especially in games that create multiple processes or D3D devices.
- Removed obsolete options to disable OpenVR support.
- God of War: Enabled performance optimizations and DLSS support. Note that these changes are already included in Proton Experimental.
More exciting is that it appears we shall be getting a new version of Proton soon, which will be rebased on the most recent Wine 7.0 release. You can see on SteamDB that the Proton team has been preparing it with a currently private Release Candidate in testing too. This should hopefully bring more compatibility for Windows games ready for the Steam Deck to release in February.
