I am also experiencing the same issue. I have been troubleshooting with the support team for about a week now and have not been able to come up with a solution. I originally thought that Windows 10 had something to do with it and was told that this is not the case, now I can confirm that it does have something to do with it. I have tried everything from reinstalling drivers to even reinstalling Windows 10. I know that v-sync isn’t a big deal, but I experience a lot of screen tearing which I would prefer not to play with.
