Vulkan: Optimize Attribute Change Perf (2/5) This patch series optimizes programs that use the pattern: for (;;) { glVertexAttribPointer(...) glDraw(...) } Change 2: Micro-optimize XFB resume CPU overhead. We don't need to set resume on every new command buffer. We only need to set the dirty bit when we have an unexpected pause. In total the patch series reduces test iteration time by 25%.
