Tracy is a frame profiler: https://github.com/wolfpld/tracy This uses Tracy's C API to instrument the code (already added in several places). It turns out there is something very weird with the fence behavior between the staging buffers and render commands as the inter-frame delay occurs in a very strangle place (in the draw code's packet acquisition rather than the fence waiter that's there for that purpose). I suspect some tangled dependencies.
