GPU Wait shows wrong data for some games in windowed mode about presentmon HOT 2 OPEN

Rendering in windowed mode (and using the PresentMon overlay in some situations/GPUs) will require extra GPU rendering/compositing work for other processes and that can change GPUWait for the target process. It also depends on things like the presentation parameters used by the application, which will vary from game to game.

From the picture above, it looks like an increase in GPUWait going from windowed to fullscreen. What are you expecting to happen, and why do you think that this data is incorrect?

Yeah that's kind of what i thought, i'm using PresentMon in detached windowed mode for that reason.

What i didn't know is that it can be normal in some games when rendering in windowed mode that GPU Wait appears to not directly equal to the time the GPU is waiting for the CPU to finish after the GPU has rendered the last frame which i guess make more sense when you look at presentation parameters or other things i don't know much about honestly, so thanks for your reply i'll see if i can dig deeper into this topic to understand it better :)
