The CPU took 0.51ms to loop from one frame to the next. The GPU took 1.1ms to render the scene.
Yes, 41.1% of the CPU time was spent inside `Camera.Render()`.
The graph shows how the performance is varying from frame to frame. The graph is showing the performance is varying between less than 1ms, and more than 1ms. In the frames that are less than 1ms, the frame rate will be faster than 1000fps. In the occasional spike the framerate will be closer to (probably) 500fps. If the spike did hit the 4ms line, then you'd get a fps of 250fps. Note that this profiler window is showing a scene which is probably rendering nothing at all, so the time around the frame loop is very very fast, and the GPU is probably only clearing the frame buffer and rendering a blue background.
