Vulkan: Optimize Attribute Change Perf (3/5) This patch series optimizes programs that use the pattern: for (;;) { glVertexAttribPointer(...) glDraw(...) } Change 3: Use FastUnorderedSet for RP XFB buffers. Most of the time this list is empty. This speeds up the count check for empty and non-empty sets considerably. In total the patch series reduces test iteration time by 25%.
