How to enable VSync on my new PC?

[sikiji]

Hey, I just built my first gaming PC and I’m having a big problem with Skyrim. I have a MSI Radeon RX 480 graphics card, an Intel core i5-7500 processor, and a ViewSonic XG2701 27" gaming monitor. My setup handles newer games beautifully, but Skyrim… is Skyrim. I’ve done a lot of digging and I know my PC is trying to render faster than Skyrim will let it, and I need to enable VSync, but I have no idea how to do that. I’ve tried many things: editing the SkyrimPrefs ini by adding iVSyncPresentInterval=1, iVSyncPresentInterval=0, and ipreventinterval=1 under display (all at separate times) and none of that worked. I turned FreeSync on in my monitor’s settings and that did nothing. I’ve fiddled around with AMD Radeon Settings changing various combinations of: framerate target control 60 FPS, OpenGL Triple Buffering, Wait for Verticle Refresh, among other things but nothing works. The game won’t stop Spazzing out and randomly crashing. Water flickers when you look at it, water flashes in and out of existence randomly in the air, creatures are frozen, the sound stutters and physics are completely messed up.

 

I’m sorry for this long post, but what am I missing? How do I turn on VSync and get this poorly coded mess of a game to function on modern technology?
