GPU usage jump shortly after starting
Quick info, I'm making a scene for Wallpaper engine. I want the scene to render with as little GPU impact as possible and since nothing moves fast in the scene, FPS doesn't need to be high. I would set it to 1 FPS if that didn't cause problems in Wallpaper engine.
The problem is when I start rendering, the GPU starts of very low (good <5 ms) and then jumps to exactly 16 ms (bad). I also monitored the GPU usage in Process explorer and it showed a jump from ~5% usage to ~25% usage. Here's the code I'm using to limit the framerate and the output of the profiler. Pausing the render and restarting it a couple seconds later resets the problem, GPU usage starts low then jumps to 16ms. Any idea on what's causing this spike and how to keep the GPU usage low?
