You might get lower FPS because it syncs it to your monitor's refresh rate, but since most people have it at like 60+, it doesn't matter.

Here's a wierd thing though... I have a GF3 Ti200, and my refresh rate is set at 75. For some reason. I can't break 62 FPS. Its not like I'm lagging to make it not break 62, it just refuses to go above that. I don't really care, it runs fine at 62 FPS (except it drops down to 30 every time I get into heavy foliage).
