Regarding ATI Radeon HD problem - Questions for people with Problem

[Raz0rx]

With Catalyst AI off, no snow was missing, but I went down and used the rod to open that metal door leading down even further and my game crashed to desktop at the end of the loading screen.

EDIT: Just tried with Catalyst AI on 'Standard' and I have the missing snow again.

An interesting picture I got when playing Black Plague yesterday.
