Lines are back and vsync didn't work. Is it just that my refresh rate isn't high enough for this resolution?
maybe you have psu problems. i had with my 8600Gt same problem. so i put a 600W in it instead of 400 non brand psu.
how much Wattage has your psu? and do you like the 3850? when not tearing?
last thing: v-sync gives you the max fps that your refreshrate of your screen can give. if you screen is at 60 hz, than you'll get 60 fps
