Greetings all!

My friend and I are playing games for fun such as Gunbound and Runes of Magic. He has a 4870x2 card and I have a 4850 videocard. I can play both of them without any problems. But his screen is flickering non stop while playing these games. He doesn't have problems with playing other games. I think that these games don't support 2 videocards so I was wondering how I can fix the flickering or how I can turn one off for him.

Friendly Greetings ;)
