How To Identify A CPU Bottleneck - Is Your CPU Bottlenecking Your GPU?

Here is a short video I did on how to set up CapFrameX for on-screen performance metrics:    • How To Setup CapFrameX For On-Screen Bench...   In this video I'll be trying to explain how to identify a possible CPU bottleneck. A CPU bottleneck is typically referred to a situation where your CPU is holding back your GPU from performing as well as it could. In this video we'll explore two typical scenarios of a CPU Bottleneck. One where the CPU is running at 100% usage, and the other where it's not, but is still holding back the graphics card. How can a CPU bottleneck a GPU when it's not running at 100% usage? Well, we explore that scenario with the help of CapFrameX, and the integration of Intel's PresentMon into CapFrameX, to help show GPU Busy as well as GPUBusy deviation. I have seen a lot of people talk about the GPUBusy feature, and also found that some of the explanations are hard to understand, so I try my best here to try and explain how to use GPUBusy and Deviation to identify a potential CPU bottleneck.
