Mesa 25.2-rc1 Released: Faster RADV Ray-Tracing, NVK Blackwell & More Optimizations
Mesa 25.2 is now branched and thus under a feature freeze and with Mesa 25.2-rc1 having just been released. This marks the start of weekly release candidates until the Mesa 25.2 stable release is ready to ship sometime in August.
Mesa 25.2 is an especially exciting quarterly feature release given the many great changes included -- especially for the Radeon RADV and RadeonSI drivers, the Intel ANV and Iris drivers, and the NVIDIA NVK driver.
Mesa 25.2 on the AMD side includes RDNA3 and RDNA4 ray-tracing performance optimizations, various new Vulkan API extensions, FSR 4 improvements, Vulkan Video support for RDNA 4 GPUs, and a variety of other performance optimizations and tuning thanks especially to Valve / Red Hat / AMD.
On the Intel side the Xe3 Panther Lake graphics are now considered stable, Vulkan Video improvements are present, Shared Virtual Memory support for the Iris Gallium3D driver, and a variety of other improvements especially for Xe2 and Xe3 graphics hardware.
With the NVK driver for open-source NVIDIA Vulkan support there is Vulkan 1.2 conformance for Kepler GPUs, initial NVIDIA Blackwell support, various NAK compiler optimizations, Vulkan 1.4 conformance for Maxwell GPUs, and a variety of other improvements.
Plus various other new OpenGL and Vulkan extensions wired up to different drivers, Vulkan 1.4 for the PanVK driver, removing of X11 DRI2 support, dropping pre-DMA-BUF wl_drm Wayland support, OpenCL 2.0 coarse grain buffer SVM support for Rusticl, and plenty of other changes along with retiring of the old Clover driver.
The brief Mesa 25.2-rc1 release announcement can be read on the Mesa mailing list.
