Hello,
This similarity is expected in most cases. The “Game” time is a reference to the Game Thread which is all of the CPU data needed that isn’t related to rendering. The CPU always handles sending instructions to the GPU, and most times it is a one to one relationship, so the CPU tells the GPU to draw a Cube with a particular Shader and it does. As a result, the time for CPU and GPU would be identical or close to it.
Cheers,
