I have my monitor plugged in via HDMI into my video card. When watching 720p video in XBMC, my CPU usage is anywhere from 10% to 15%, and my GPU usage is only at 6% to 9%. I would think, since the monitor is plugged into the video card, and not directly into the motherboard's HDMI, that the GPU would be at a higher usage percentage. Is this situation "normal"? Thanks.
