Actually , I just have something to report .
I just bought the game "Tom Clancy's Rainbow Six Siege" recently . And something went wrong with my computer when I run this game.
This problem is about CrossFireX technology,
If my CrossFireX turned "on" , then the game graphic starts flashing . Once CrossFireX is "off" , then the game will work just fine .
I tried 3 different versions of GPU drivers, Catalyst 15.7.1、Catalyst 15.9.1 beta and Crimson 15.11.1 .
The problem can't be solved by simply updating new drivers .
So I want to report this problem , since I cant find support E-Mail , so I just submit this problem here , the forum.
Hope somebody can see this problem ,
and if your 2 GPUs work just fine on this game , please tell me so I can know this problem only happend to me .
Oh by the way , my computer is set up with 2 R9 390s built by ASUS , R9 390 STRIX 8GD5.\
