Developer Philip Rebohle today announced the release of DXVK 1.5.5, bringing with it plenty of bug fixes for this impressive Direct3D to Vulkan translation layer.
On the games side, quite a number had specific issues addressed with this release. You should find less issues running: Book of Demons, Close Combat, Cross Racing Championship, Dungeons and Dragons: Temple of Elemental Evil, Elite Dangerous, Evil Genius, F1 2019, Hyperdimension Neptunia U Action Unleashed, Just Cause 1, Lumino City, Saint's Row III / IV, Shade Wrath of Angels, Sins of a Solar Empire, Rocket League and Vampire: The Masquerade Bloodlines which should see improved performance.
Another tweak was done for Skyrim, this time fixing both crashes and incorrect rendering with the "d3d9.evictManagedOnUnlock" option, they say this is "useful for Skyrim with a large number of mods as an alternative to ENBoost".
There's also more D3D9 features implemented, Intel hardware sees better D3D9 compatibility and more bug fixes included.
If you wish to upgrade your existing Proton install without waiting for Valve/CodeWeavers to update, it's quite a simple process of overwriting the existing DXVK files with the release download of DXVK 1.5.5. You can find your Proton install somewhere like this:
Where x.x is whatever Proton version installed you wish to give a new DXVK.
Inside there you will see "lib" and "lib64", for 32bit and 64bit. Inside each of those, there's a "wine" folder and inside there is a "dxvk" folder and that's where you replace the files with new versions. Do so at your own risk but it's usually harmless. If you mess anything up, to refresh it you can usually just re-install Proton from the Tools menu in Steam.
