I'm not sure what the problem could be. I'm using a 64MB GeForce2 MX 400. I have DirectX9c installed, as well. I realize that my video card is outdated, but it never had problems displaying RtCW's graphics properly before. Check out this screenshot:
What's wrong with my display? I'm assuming that the issue is with rendering shaders and whatnot, but I'm not sure what I can do to correct it.
Used any tweaks or are you using beta drivers for you video card? Did you change something that might be the cause of this, tried reinstalling?
Well, I was originally using tweaks to brighten my display, but I removed all of the tweaks later on whenever I noticed the problem. The tweaks are now back in place, as I now know that they weren't the culprit. Oh, and I'm not using beta drivers. Could DirectX9c be the problem?
By the way, the fog doesn't really look like fog at all. You can see the brushwork making up the fog, in fact, but you can't see the fogginess of it. It definitely ruins the atmosphere in the crypt. :P
