A significant ray-tracing performance improvement for AMD's RADV Vulkan driver has been merged into Mesa 26.0. This update, which was initially covered earlier this week, is specifically aimed at enhancing the performance of Unreal Engine 5 titles that utilize Lumen, particularly when running on Linux systems through Steam Play. The integration of this improvement is expected to deliver substantial performance gains, directly benefiting Linux gamers and developers using AMD GPUs for ray-tracing workloads in UE5.
