Know your vsync

If the computer cannot get 30 fps, say it gets 29, then vsync will make it fall to 15 fps because 60/15=4, a whole number for whole frames.

So use it knowingly.

This is correct but can be fixed by switching triple buffering ON in Direct3D.

Enabling Triple Buffering for OpenGL-based games such as Doom 3, Quake 4, Prey or Enemy Territory: Quake Wars is very simple - go to your graphics card's control panel and enable it from there. However enabling Triple Buffering for Direct3D-based games - the bulk of modern games - actually requires more effort. You will need to use a utility called D3DOverrider which comes with RivaTuner - see the bottom of this page of my Nvidia Forceware Tweak Guide for more details.

ATI Tray tools also does the trick for AMD cards (read its help file/manual for instructions).
