For those who have an ATI card and picked up Red Faction Armageddon you may have noticed that the DirectX 10/11 modes are buggy. Currently the only solution is to use DirectX9 which is stable and loads faster.

DirectX9 is also currently performing much better than DirectX10/11 on ATI cards, people have reported to be getting much better performance while the graphic quality remains pretty much the same.

From a thread on the official steam forums, the only people who seem to be having this problem are those with ATI cards.
