Two separate graphics driver updates aim to improve cross-OS application performance. Microsoft's dxgkrnl driver (WSL2's DirectX bridge) has received its first update in four years, now supporting compute-only GPUs for LLM workloads, multiple virtual GPUs per VM, and dma-fence buffer sharing. On the WINE side, a new OpenGL extension called MESA_map_buffer_client_pointer solves a long-standing issue where 32-bit Windows games running on 64-bit Linux or macOS couldn't receive 64-bit GPU buffer addresses from glMapBuffer, eliminating the need for slow memory copy operations. WINE continues to benefit from Valve's investment via Proton and SteamOS, and WINE 11 has fully integrated 32-bit-to-64-bit thunking.
