It requires the NVIDIA R615 Linux driver or newer plus VKD3D-Proton 3.1, and speeds up ray-tracing through alpha-tested and semi-transparent geometry. The release also adds an alternative NVIDIA Reflex implementation for Vulkan games using the VK_NV_low_latency revision 2 extension, which makes the DXVK-NVAPI Vulkan layer obsolete for that purpose. It also supports new settings from the R610 and R615 drivers, improves free VRAM reporting, and adds ARM64 compilation support. ## Full article daily.dev links to this article rather than hosting it.
