nope, the choppyness is only when an ocasional thing, in counter-strike for instance, it was chopy when the map loaded for a bit, the first time i picked up a new weapon it would stuter and the first time i used a sniper zoom the same thing. this was only when i had vid-sync on, but the refresh was at 60hz an i belive i eventualy found a way turn it up to 75 befor i uninstaled it, but it was still chopy. btw i went through all the bios settings and confirmed both optimal and compatablity settings with 3rd party programs like sandra and wcpuid. my systems is fairly current and basic, socket t-bird on an epox board, 128mb 133pc-133, soundblaster live, cheap nic good powersuply and so on. the only preformance inhibiter i have is that im running at udma33, but the hardrive is not active during the choppyness so i doubt thats it. everything runs incradably stable and cool, 28/38 is the most i have seen for case/cpu temps respectivly. the card runs smooth as silk with vid-sync off, but tears like tolet-paper. so i ask all you nvidia owners, do you use vid-sync on your card?
