Flickering/Unsteady Edges

[Urrah]

Strange, the problems you're describing are known issues but I thought that they only existed on ATI cards.

If you've tried changing the graphics options and going through the troubleshooting thread then I'd try reinstalling the game.

If that fails you could try playing in windowed mode, I have found, oddly enough, that this solves all the graphics problems I was experiencing (although windowed mode is no where near as immersive as full screen).

Looking at your hpl.log I see that you get the same "does not exist anymore" text that others experiencing graphics problems get, if you don't want to get a new graphics card you'll probably have to hope for a patch.

The only other common denomiter I can think of is that a lot of people having graphics problems are on 32 bit systems, being a noob I've got no idea if this has anything to do with computer graphics.

Sorry I can't give you more help but know that you're not alone, and keep your fingers crossed for a patch.
