I am unfortunate enough to get Arma 2 just as my new video card breaks, so I have to use the old one that came with the case. Unfortunately, it got problems.
ATI Radeon HD 4300/4500 Series (512 MB)
Dell Windows 7 Home Premium
Studio XPS 435t

The frame rate is fine (With low-enough resolution.) but, as the pictures can show, the triangles that make up the world start disappearing, connecting to a random part of anything. It's horrifying, so I must ask what is the most likely problem causing this?
