I'm running no mods, I had a texture pack running but have tried turning that off. I have uninstalled it and reinstalled it like 4 or 5 times now, and while the errors only started part way through the game, it still happens if I load a previous save file. I'm not 100% sure how to verify the integrity of the files.
Here is how to verify the integrity of your game files on steam. It usually shouldn't be necessary with a fresh clean install, but it doesn't hurt to try. I'm also assuming you are playing through Steam, which you might not be.
So, you tried a clean install of Skyrim, loaded up an old save from before the glitch started happening, and it was still present there?
When did the glitch start occurring? If you start a new game from a clean install of Skyrim, does the glitch occur then as well?
I'll try that as soon as I have time, but yeah clean install, loaded an old save, no luck. New game also doesn't help its like the gpu decided to take a **** but only on this game... haha I don't know if theres some incapability issues. I'm running an amd 580 red devil gpu, ryzen 5c processor.
As @Oussebon says, try to go into detail step by step of how you've gone about uninstalling mods, reinstalling the game, etc. Sometimes it's the little things that can be overlooked and cause a tangle in Bethesda's spaghetti basket that is Skyrim.
Just for fun, try updating your GPU drivers and launching the game in windowed mode with v-sync turned off.
I think you should rotate your monitor 90 degrees counter-clockwise... Joking aside, I'd try setting some framerate caps in the Nvidia control panel to see if that resolves your issue. Anything over 60 is probably a bad idea for Skyrim. I'd also try turning off any ULMB, lightboost, or other fancy features your monitor may have.
