Yes, that is what I remember too. VSync would stall rendering. I believe I would get something like 5 more fps with it off on quake. But I tested it with UT and it didn't make any difference (under 1fps difference). That is weird option to leave in their if it doesn't make any difference. I wonder if the windows binary is the same...
