GPU-AV Runtime Performance Regression

Open spencer-lunarg opened this issue 8 months ago • 1 comments

Follow-up from https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/8016

From here https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/8016#issuecomment-2117064642 when we started re-working GPU-AV (which fixed bugs and added edge cases not being check before) around the 1.3.268 SDK timeframe, we introduced a very drastic runtime perf regression

We have already narrowed it down to the shader instrumentation causing the runtime to just drop

We are going to need to find a way to regain some performance otherwise GPU-AV is not practical to use
