High overhead #90

This tool puts a significant dent in performance when running. I was trying to use it to record some benchmarking numbers and the framerate dropped from about 1000 to 500 by having this program enabled.

Hi! I would need a bit more information to investigate the problem. Which OCAT version are you running? What are your system specs? On which program did you use OCAT to do benchmarking and what were your OCAT settings? Did you enable the OCAT overlay or just had OCAT running in the background without the overlay hooked into your program?

A small overhead is expected when having the overlay enabled. You can disable the overlay during capture to reduce the overhead, or not hook in with the overlay at all and just get the frame captures via the hotkey for offline analysis. FPS drop from 1000 to 500 sounds still in a reasonable range with the overlay enabled - so will not fix. Please re-open if you still think it's a problem and add more details to the specific issue, so I can help you out :) Thanks!
