Remember there are already 1000's of prior discussions on topic so what I'd look for if you can't stand vsync is buffering. Try double and triple.
The 760 isn't high end so you would check what framerates folk get and if under 60, reduce effects and settings. If over 60, use the usual framerate cap and buffering.
Again, so many prior discussions that I'll take you read those which is which I won't dive too deep here and share the usual or solutions I find to help.
I just built my own gaming PC about 5 months ago (Windows 7) and it's been working great, until about 2 weeks ago where the screen starts to tear on certain games, I thought maybe it was the monitor or the cord but I tried a different cord and a different monitor screen and it still happens. I brought my PC into the office for this reason but he has had no luck.
I'm aware of the v sync for NVIDIA, but it's been causing a fair amount of slowdown, and this hasn't been a issue until now, so there must be a way to fix this.
If anyone has an idea of a way to get it working back to normal that would be fantastic.
