From what you are describing, I’m afraid I may have some bad news.
The very first thing I would do is to make sure you uninstall and completely reinstall windows Direct X. Please make sure you do this and try the game again, before doing anything else.
I would try doing a system restore, if you have this enabled in windows vista and beyond. Unless you disable it yourself manually or ran out of ahrddrive space, there will be snapshots of your computer before major driver updates.
My suggestion would be to restore back to the of the driver and uninstall it completely and then install the video cards drivers.
If this doesn’t work, then I would suggest testing your video cards memory. If certain addresses on the video card is corrupted, textures will start to disappear and cause crashes. Not only that, textures will vanish and reappear depending on the rendering type and angle.
I believe that if its not software related, the video card itself is at fault… most likely from faulty memory. Memory issues are annoying because certain games will work perfectly while others will not; they are hard to troubleshoot.
You are caught in a bind because you have an issue that no one else is experiencing and unfortunately even the paid techs in support can’t give you much information other than update your drivers or reinstall. If all else fails, you’re just going to have to reinstall the operating system or get a new card.
Most tech problems are user related and the paid techs are simply there to help customers who aren’t familiar with computers the best they can. There are several issues that could cause this problem out of the scope of basic techs, because the tech support simply solves problems that happen often; not ones that apply only to you. I’m sorry that you had to experience this; but it won’t be the first time.
