Mesa 25.1-rc2 Released With NVK Vulkan 1.4 Conformance For Older NVIDIA GPUs
Mesa 25.1-rc2 is now available for testing as the newest weekly test version of this collection of OpenGL and Vulkan drivers. Mesa 25.1 continues working its way toward a stable release in May.
Notable with today's Mesa 25.1-rc2 release is back-porting a change covered yesterday in Mesa Git: Vulkan 1.4 conformance with the NVK driver going back to the GeForce GTX 750 / 900 series "Maxwell" graphics processors. This also includes the GTX 1000 "Pascal" and TITAN V "Volta" graphics processors too as up until now only the Turing GPUs and newer were certified for Vulkan 1.4 compliance. A nice milestone for the NVIDIA GPUs on the open-source Vulkan driver albeit the Nouveau kernel driver support on the GTX 900 series and later still is less than ideal (namely stemming from the signed firmware requirements) and it will be a while before the NOVA driver is ready for end-users with the RTX 20 series and newer. This leaves the GTX 900 and GTX 1000 series hardware in a tough spot for the open-source space.
The Mesa 25.1-rc2 release also lands a number of fixes for the Apple graphics drivers with Ashai Gallium3D and Honeykrisp Vulkan, a RadeonSI VCN decode fix for H.264 interlaced streams, re-enabling compression for CPS surfaces on platforms other than Xe for the Intel ANV driver, and various other fixes throughout.
