So, I'm having a problem with certain effects in the game turning my screen pure black, and the threads over at the Nexus tech help section never get any replies.
I first noticed it when I picked up the Staff of Corruption. Whenever I cast it, the screen turned black. My game wasn't frozen, and I could still perfectly see the GUI elements. If I happened to stumble near an object or door, I could see the "press E" popup just fine. But it's like I had 100% Blind cast on me.
I tried various things, changed my mod order, disabled mods... nothing seemed to help. Since it was the only occurance I had come across in ~40 hours of play, I decided to just not use the staff.
Later, when going through the Mage College quests and helping whats-her-name by being a spell test subject, it happened again. She cast her "I turned you supar-green" spell on me, and my screen went black.
In both instances, if I open my map, I get visual back. But when I close my map, it goes black again. I can briefly see the world before the darkness encroaches. It 'fades' to black, rather than a sudden flicker. This weird fading behaviour makes me suspect some sort of shader problem.
So. Shader problems... how exactly does one fix those? Are there any ini settings I can try changing? My gfx card is a single ATI 6850.
