--- Comment #21 from Kai Krakow kai@kaishome.de --- I lately tried Wine Staging with Witcher 3 and it was performing really bad with Witcher 3. Are there chances that people seeing really bad Witcher 3 performance using Staging? Especially the D3D11 deferred context patch series is problematic. Using vanilla or not using D3D11 deferred context patches makes the game run much better (almost smooth).
I also tried DXVK (which compiles as a separate set of DLLs, no patching needed, uses Vulkan) and besides lots of ugly graphical glitches, the game runs perfectly smooth (60+ FPS with some rare stutters what is probably caused by shader compilation). With DXVK, also Skyrim SE runs without problems and perfectly smooth.
