Stutter in Intervals

[Pit-O-Matic]

Hello there!

Every game stutters a bit in intervals for me. While it isn't that noticeable on games that run on 30fps, games like Valkyrie Profile 2, SSX Tricky and Ratchet and Clank 3, who run at 60, feel really choppy now.

Basically what happens is: The game runs great for like 8 seconds, then it stutters for like 3, and it's back to being smooth, repeat. It doesn't matter the settings or if I even move in the game.
Weirdly enough the speed shown is constantly 100% (59.79 - 60.10)

System:
Nvidia GTX 970
Intel i7 6700
16 GB Ram
Windows 10

Are you using any non-default speedhacks(or a more aggressive preset)?

EE Cyclerate and VU Cycle Stealing are both on 0, everything else is enabled outside of fast CDVD, preset is on 2- Safe.
Though disabling speedhacks altogether doesn't help either.

I think I know what the problem is, it's the forced triple buffering in Windows 10. I tested a few things and it also happens on other emulators like Dolphin when borderless is enabled, so I guess PCSX2 doesn't have exclusive fullscreen?

Right now using the renderer Direct3D11 and enabling Vsync fixes that, but I'd much prefer OpenGL, but Vsync doesn't seem to work there for some reason.
