The second weekly release candidate of [1]Mesa 25.3 is now available for testing ahead of the official release in the coming weeks for this quarterly feature update to this set of open-source OpenGL, OpenCL, and Vulkan graphics drivers.

As mentioned last week when [2]Mesa 25.3 was branched and Mesa 26.0 began development , this Q4-2025 feature release is going to be particularly heavy. Mesa 25.3 brings a lot of AMD RadeonSI/RADV, Intel ANV and Iris, and Nouveau/NVK changes as usual from new Vulkan API extensions to performance optimizations. There is also a lot of improvements still for the Zink OpenGL-on-Vulkan driver, the PVR PowerVR Vulkan driver continued growing more capable, and a lot of improvements to the other smaller drivers. Plus the new Gallium driver for Arm Ethos NPUs and many other improvements. Beyond the usual heavy churn to the Intel and AMD Radeon drivers, NVK continues seeing a lot of excellent and vibrant work.

With Mesa 25.3-rc2 released overnight there are a number of NVK and NAK compiler fixes for open-source NVIDIA fans and various AMD and Intel driver fixes. On the Radeon side are even some fixes for old hardware: updating nplanes support for the R600 Gallium3D driver and fixing DXTC blits for old Radeon R300 class hardware.

The full list of Mesa 25.3-rc2 fixes for the week can be found via the [3]mailing list announcement by current Mesa release manager Dylan Baker.
