Re: In game FPS display stats meaning

I believe that:

• CPU = the number milliseconds between each draw request to the GPU
• Sim  = IDK (turns out it's a measure of input latency, from what I can see online)
• GPU0 = the number of MS between potential GPU frames
• MP/s = megapixels per second

On that image, your CPU is the limiting  factor, as it is requesting fewer frames than the  GPU can actually draw. I might be totally wrong about CPU though.
