Ok. HighFPSPhysics worked for me. I can now play at 1440p. Thank you.
But now there is a new issue, that I believe i've isolated to BethINI, or some setting BethINI can change.
I think the screenshots speak for themselves, I have this odd pixel effect on all my textures, as if there was a pixel grain effect over all of them. I think it mainly applies to shadows.
This one shows the issue over the entire wall. This one is the most obvious and clear.

This one shows it pretty hard on the vertical wall piece, Nora's neck, and the shadows of the chair

This is a brand new install of Fallout 4, which I am tinkering with to get working with a few mods. But once this started. I nuked everything and reinstall the game from scratch. Then, I installed things one at a time to see what was causing it, since I don't get the issue in vanilla. Right now I have MO2, BethINI, and HighFPSPhysics installed. That's it.
Any help would be appreciated.
