Performance Issue with No Motion Blur
We ran an overnight soak test to check for performance issues over long term play sessions and came back to a Frame Time over 70ms. Using the 'stat scenerendering' console command we found that 'DeferredShading.SceneRenderer.MotionBlur.FrameStart' was taking 65+ ms to render. Our project is a VR game that uses Forward Shading with Motion Blur disabled by default so the fact that this is appearing is really strange. Using 'stat gpu' we found that Slate3D was taking around the same time to render as the Motion Blur. We have some widgets in the scene, but nothing that should be taking that long to render. We are currently trying to find what could be causing the issue, but are having a hard time figuring it out. Any ideas as to what could be causing this?
