Shouldn’t it be always full for any frame analyzed? Even if it’s not a bug or an issue, what does this mean? How am i supposed to interpret the data? p. At the GPU Visualizer(ref) In Editor, if you type `ProfileGPU` in the console, you can dump a current frame and get a visual version of the data in the GPU Visualizer. However, I don’t really need the shadows to be all that crisp, in fact, blurred shadows would The performance of my editor varies greatly when I start my project, even if nothing in my scene changed. Undoubtly the upgrade would be the best, but by the lack of this option you can reside to micro optimizations by reducing the content’s density, eg show less amount of grass and cut the non-essential content (gameplay wise) in My FPS now increased but LightScattering increased in time in GPU Profiler. RHISetGPUCaptureOptions 1 in console, it'll set up the GPU Visualizer to show each mesh/material's draw times Is there a way to determine the cost of collisions in the processing time per frame via the VISUALIZER or some other tool?
