We've received some reports that the the shader fix in Beta 1.1 is causing intermittent crashes on systems with Nvidia graphics cards. We have narrowed the problem down to an interaction between the shader and per-pixel fog effects. This appears to be either an Unreal or a driver issue.

This hotfix temporarily disables fog until we can find a workaround or implement a proper fix.

Thanks for your patience and your support!
