144 fps FullHD for capturing can't be serious.
At least, you can try to enable Limit capture framerate option in 'Game Capture' - this reduces twice the attempts to capture frames in current build of the OBS Studio (don't use Display and Window capture because they both lack this function).
Don't get me wrong, I'm gaming at 144Hz, but I simply want to record at 60FPS which happens to be my CAP in OBS.
