Jagged/Flickering/Shimmering textures/shadows in all of my games

[Darkstarr11]

This is an issue which happens in all my games (including minecraft). The issue started when I upgraded from AMD 7870 GHz Editon to a Asus 980 STRIX.
Here's a youtube video showing the issue: https://www.youtube.com/watch?v=rlg4C0_3fUM
Also, when in-game the shadows are really pixelated even when maxed out.
I have already done the following to try and fix the issue:
Re-installed drivers for gpu
Updated the BIOs
Removed new card and put the old one back in. (and the problem still persists)
Refreshed windows

My specs:

Asus 980 Strix
i7-4770k @ stock
16gb Corsair Dominator Platinum
Win 8.1 64bit
1920 x 1080 acer monitor

Since the issues persist when you replace the old card, the first thing that comes to mind is a driver issue. Did you uninstall the old drivers fully before switching cards? I suppose that kind of glitch can occur if the PSU isn't providing enough power, though I'd imagine switching to back to the 7870 should alleviate the issue if that were the case.

There are zero issues, that is called aliasing, and it is common in all games from the dawn of the 3D, even 2D games get it. As 3D games have advanced recently with far more detail in textures, this aliasing has become a lot more difficult to remove. New rendering methods and DX11 has made it worse. To fix those textures you see in Skyrim, it would take SSAA, and the game doesn't support SSAA, although it might be possible to force on from Nvidia Inspector (google SPSSAA or sparse grid ssaa with nvidia inspector).

FXAA helps a little, downsampling can help as well. SMAA isn't a bad way to go either, as it is similar to FXAA but better. SSAA is extremely demanding from a VRAM and GPU power point of view, so it may not be practical.
