Because the main Amnesia campaign, Justine, and almost every mod I've downloaded has worked 100% for me. It's just my own custom story that fails on me and I don't know why. It may be the 5,000+ entities in two small rooms, or whatever else it could be, I'm just glad you could pinpoint the problem on my HPL. I can't really buy a new video card at the moment, but thanks so much again!

Well, despite the lack of 2.1, if the original game renders just fine, then the problem is probably elsewhere.
In that case, have your custom maps ever worked?
Have you set up a proper development environment for custom mapping (according to the wiki)?
