VKD3D-Proton 2.8 Brings Many Improvements For Direct3D 12 On Vulkan

VKD3D-Proton 2.8 has been released as a nice Christmas gift to Linux gamers for advancing this Direct3D 12 on Vulkan implementation that is part of Valve's Steam Play (Proton) for enjoying Windows games on Linux.

VKD3D-Proton 2.8 was just released and it adds support for VK_EXT_descriptor_buffer that can be used for removing "a ton of CPU overhead" otherwise. This is working already with the RADV Mesa driver and the driver shipped by the Steam Deck while this new work in v2.8 also gets it into shape for the NVIDIA and Intel drivers along with other Vulkan implementations. GPU-bound performance should also improve slightly too.

The VKD3D-Proton 2.8 release also has rewritten support for host-accessible images, rewritten swap chain support for reducing CPU overhead and various game fixes, and other improvements.

Witcher 3, Age of Empires IV, Borderlands 3, Guardians of the Galaxy, RE: Village, and Spiderman Remastered are some of the games mentioned that should specifically benefit from VKD3D-Proton 2.8 improvements.

More details on the VKD3D-Proton 2.8 update via GitHub.
