post #1 of 5
Thread Starter 
I have vsync on in BFBC2 and it is 60fps, holds there well, but with 2 6950s unlocked and oc'ed and vysnc off i get around 100fps. Is vsync good to use or bad?

If you turn on v-sync it will force your framerate to be 60 as your monitor can only display 60fps max (Unless its 120hz in which case its 120fps), if you turn it off you will get screen tearing which is frames being pushed out above 60fps and the screen 'picks' which frames to use so its not constant and looks yuck
I suggest you keep it on

smoothes gameplay at the expense of input lag and low frame rates

I use it for every game, it pretty makes it so the max fps is 60. It eliminates screen tear but there is some mouse lag, I can't feel it but others say that there is.

If your playing FPS then you might notice it but I haven't yet in BFBC2.
