V-sync???????????

What is v-sync (i assume it means vertical synchronisation) and how does disabling it
make the frame rates of games higher.

It may make the FPS higher but it is at the expense of image quality and the horrible "tearing" effect. I prefer to leave it enabled unless I am benchmarking.

It can also depend on what Hz you monitor is set at...
