A new version of DXVK, a Vulkan-based translation layer for Direct3D 10/11 which allows running 3D applications on Linux using Wine has been released.
FeaturesDXVK 1.3 released
Discard optimization
The new VK_EXT_shader_demote_to_helper_invocation extension is now used to implement the discard instruction in shaders, which may improve performance in some games. This requires a winevulkan update, as well as the following driver versions:
AMD: Not supported
Intel: Mesa 19.2-git
Nvidia: 418.52.14
Asynchronous presentation
In order to reduce stalls on the main rendering thread, presentation is now being performed on the command submission thread that was introduced in DXVK 1.2. This can improve performance especially in scenarios with high frame rates and when command submission is expensive.
One game that benefits is Quake Champions on AMD GPUs.
Resource upload chages
If available, DXVK will now use the copy engines of the Vulkan device for initial resource uploads. This may slightly improve frame time consistency if a game loads a large number of textures during gameplay. Currently, this is only supported on the AMDVLK and Nvidia drivers.
Bug fixes and Improvements
Removed busy-waiting during presentation. This change will most likely not affect performance, but can reduce CPU load considerably in GPU-limited scenarios.
Improved error logging in out-of-memory conditions (PR #1112)
Improved MSVC compatibility (PR #945, PR #1110)
Fixed incorrect behaviour when an already mapped image subresource gets mapped again. Encountered in Final Fantasy XIV.
Scrap Mechanic: Fixed crash caused by incorrect RSGetViewport behaviour (#1116, PR #1117)
