I use a laptop with a GT720M and an i5-4200M running Windows 10. It's a slow setup but im encountering a problem i didn't have before. I experience extreme screen tearing. I have to use V-Sync with every single game I play. I have no idea why it started and I'm sure the problem is not my monitor or gaming performance. For example, when I play Battlefield 3, 720p, low preset, it looks like it only displays 18 or 22 frames but when I turn on v sync, it's completely playable around 30 to 40. The obvious solution would be use V-Sync 24/7 but I have no idea why my potato got even worse. I would appreciate help. My driver is 391.24. That's the latest driver I can find that supports my fermi mobile gpu so driver update probably isn't a viable solution.
