My game was working fine a couple days ago. Suddenly, last night it decided to start flickering on water textures and walls after I alt+tabbed. This is completely unacceptable. Does Bethesda STILL have alt+tab issues? I had these problems in Morrowind, Oblivion, and Fallout 3 years ago. I'm using Nvidia's 296.1 drivers (I won't update them. Last time I did, it completely debacled my PC and I had to re-install Windows)

I'm trying not to rage, but this is so typical of a Bethesda PC game. The same issues persist time and time again.

If you are unwilling to update your drivers then we can not help you. The 301.62 I believe they are now, are what you need. They have a fix in it for 580 in SLI. But if you are unwilling then move on.
