CPU Busy Showing Wrong Value

Open dietahvr opened this issue 7 months ago • 0 comments

CPU busy is not showing the working time of the CPU for the Frame but rather showing the time for outputting a finished frame. So it always shows the same Value as App Framerate.

Here A screenshot of presentmon overlay next to the tool that exposes "frametimes" for steamVR Games. You can see that GPU Busy is displaying the value it takes the GPU to finish one frame, but on the CPU it just shows the value in ms that is matching 120fps.

I really hope that this can be fixed to actually show the time the CPU spents actually working on the frame. Since this Value is essential for performance monitoring as well as CPU Comparisons.
