hey everyone, i was wanting to know what v-sync is/does so searched around the net and got myself educated on the matter but im confused. my understanding is its a limit of the graphics card to never go above the refresh rate of your monitor which equals fps, like a 75hertz refresh rate = graphics card limited to 75fps? thats my understanding of it. if im wrong someone please correct me. but my question is with dual graphics cards, is v-sync needed? should i use it? also i read that only really applies to crt monitors and not lcd even though lcd has refresh rate the article said it really doesnt apply to lcd. since ill have SLI configured graphics soulution, the image on the screen is split in half and one card does the top and the second does the bottom so i should have no tearing or ghosting issues, right? again correct me if im wrong. all replies/corrections appreciated.
