Graphic/Texture issues.

Posting this because it's gone from a nuisance to a serious issue. Now the ground on which I tred to do my zombie killing is covered in Purple and Black checkerboard markings, and most if not all of the props are massive "ERROR" signs. This happens in L4D2 as well, any idea how to fix this?

The game is probably missing some files.

Right click Left 4 Dead, properties, and go to the Local files tab. Then click on Verify integrity of game cache, and Steam should check if all files are there. Steam should then start downloading any files if they are missing.

What does your console look like?

67 files could not be validated and will be redownloaded

Well then, let's just see if that is the case.

Alright, that fixed it. Thanks all!
