Sample rate shadingįor older games that support MSAA, the d3d9.forceSampleRateShading and d3d11.forceSampleRateShading options were added to let users enable sample rate shading for all shaders. Note that the implementation is not yet complete and does not support shader caching at this time, but it should generally work with DXVK. Note: Current development builds of RADV will expose VK_EXT_graphics_pipeline_library with the features that DXVK needs if the RADV_PERFTEST=gpl environment variable is set. Additionally, more features of the VK_EXT_extended_dynamic_state3 extension are leveraged to reduce stutter in some situations when MSAA is used, provided that the Vulkan driver supports them. Use of pipeline libraries was extended to pipelines with tessellation or geometry shaders in order to further reduce stutter. Additionally, only Nvidia drivers are expected to work on Windows. Note: D3D11 support is implemented, but not expected to work in most games as they typically require AMDAGS or NVAPI to set up HDR output, rather than using the corresponding DXGI APIs. This is currently only supported under AMDGPU and requires kernel patches from the josh-hdr-colorimetry branch. In order to use this on Linux, a Gamescope session with -hdr-enabled is required. No major Linux desktop environment currently supports HDR. When using vkd3d-proton 2.8 or newer, this will allow D3D12 games to detect and use the HDR10 color space if they support it.

On systems supporting HDR10 color spaces, HDR can now be enabled by setting the environment variable DXVK_HDR=1, or by setting the option dxgi.enableHDR = True in the configuration file.
