How much does framerate affect CPU?

[MyName13]

What would be the difference in cpu usage at 30 fps and at 60 fps?Has anyone ever tested this?

It depends on how cpu intensive the game is. If the game is heavily cpu intensive then limiting your frames to 30fps will reduce cpu usage.

Of course, I know that, but is here any benchmark that shows how much of a difference there is?60 fps is twice as much as 30 fps so it would be interesting to see how CPU heavy draw calls are.

Each game uses the cpu in different ways so there is no way to standardize it in a way that allows you to say you need 2x the computation power to double your frame rate. 
You could benchmark certain games like City Skylines or Rise of the tomb raider with different framerate limits to see what they does to the cpu load when playing those games.

That's not really the right question. If a CPU would be capable of delivering more FPS then that means that you probably have an underpowered GPU. If the CPU is at 90-100% usage at whatever FPS then the CPU is the bottleneck rather than the GPU.
