Hi list, I'm using Lavapipe for Vulkan software rendering support in a modeling application. I notice a large performance hit (with any Mesa version) in the following scenario: The user clicks & drags the mouse in order to create a simple shape (e.g. plane, cube, sphere) dynamically and the result is being rendered (basic gray shading) in real-time alongside the movement of the mouse. Lavapipe seems to be struggling a bit to keep up with this action as the frame time goes up to over 1 second. On the other hand, on a more "static" scene I can get great fps (30-60) while panning/rotating a scene, after Mike Blumenkrantz's recent improvements (many thanks for those again!).
I've uploaded a screenshot of the VS profiler showing the hot path at https://imgur.com/a/qZBkB51 and I'd appreciate hearing your thoughts on this. Thanks once more for your time. Best regards, George
