Vsync in Windows 8.1

[-Dant-]

Hi, I have a laptop that has an Nvidia Geforce 710m mobile videocard (OS win 7 64x), and in PPSSPP 0.9.9.1 v-sync also doesn't work for me. In official 0.9.8 release it worked, although not perfectly, but still better than in the latest version. So it seams the culprit here is the emu, not the videodriver. Oh, and v-sync only works if I turn it on in the driver's settings: ingame one doesn't work.

I also have another problem, related to videocard and v-sync - stuttering. For some reason if I enable v-sync in 0.9.8 version, games would occasionally stutter. Without v-sync games, for the most part, don't stutter, but there's a horrible level of screen tearing, which kills the smoothness. Unfortunately, driver setting "Max. number of prerendered frames" doesn't eliminate the problem. It looks like the stuttering occurs at the same time when there should be screen tear, and it could last for several seconds: it feels like as if the emu started to drop frames, although it doesn't.

Hope something could be done to resolve these issues.
