Until this evening I had sharp texture definitions and very fine outlines on all the models. Now the outlines are thick black lines and my textures have lost definition. It is also making for very choppy movement. It doesn't appear to be an FPS issue. Also, when I would teleport, the world kept its colors and textures. Not it turns greyish purple.

Pics to show what I'm seeing:

I don't know what happened to cause this. I've uninstalled / reinstalled 4 times. I've even cleaned out my registry.
