If you have vsync turned on, your video card sync your fps with your refresh rate. So if you have your refresh rate set to 100, you can only get a maximum of 100fps. If your video card can't keep up, it renders half of your refresh rate I believe. So just turn it off, it will not ruin the video quality.
