Vulkan: Optimize Attribute Change Perf (4/5) This patch series optimizes programs that use the pattern: for (;;) { glVertexAttribPointer(...) glDraw(...) } Change 4: Inline ValidateProgramDrawStates. A hotspot in most draw calls that change state. In total the patch series reduces test iteration time by 25%. This change reduces the listed "null" benchmark time from 295 -> 286 ns.
