As mention in this forum by me : http://www.rage3d.com/board/showthread.php?t=33935366

There is a crash probably related to ATI drivers but It tough it would be great to report it to the demigod dev.

This is a bug I consider major since it introduce a complete system crash and should be resolve asap by ATI or GPG if its the game causing it.

A complete how to reproduce is on the thread. If you need more info on How-to reproduce, feel free to ask me.

This affect only the 4870x2.   the 3870x2 are not affected.

The crash is not instant when starting a game. YOu must play around 5-10-15 min. Its not always the same. Normally you wont have time to finish a match vs the A.I

THis issue is verry random and not easy to pin point an exact cause. But I suggest to read this over amd forum. LOT of people experiencing this similar issue with World Of Warcraft. http://forums.amd.com/game/messageview.cfm?catid=260&threadid=99235&enterthread=y

Also keep in note that this problem may be something not right in my system as I test some other things too.
