Nemesis Dragon, what you said only holds true if you set v-sync to true. What v-sync basically does is to try and "match" your fps to the herz from your monitor. That can either be the same fps as herz or half (in case of triple buffering it can be 1/3 2/3 3/3). The reason why you want to turn on vsync is to get rid of "tearing" (looks like two textures not lining up correctly and you get a white "line") which might happen if your monitor can't keep up with the high fps. If you have v-sync turned off fps can get higher then the herz from your monitor, which may give "tearing" as described above.
In any case I have vsync turned off and besides I play with 100hrz <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
The people with 60+ fps, what kind of systems do you have cause I got the feeling something is not entirely okay with my pc & beyond divinity fps <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
