Hello Dear. I come from China.I bought a Lenovo laptop models Lenovo IdeaPad Z485A-AEI. Laptop configuration: AMD-4500M, 4G DDR3 1600 memory, AMD 7640G+7450M graphics card, 500G hard drive.I was playing the valve Dota2 game.I now use the display card version AMD_Catalyst_12.101.2.I use your graphics card game optimization file: CCAPs 2.4.My question now is: the driver has been properly installed, the default mode or to use AMD predefined configuration file can not be enabled dual-graphics Crossfire.Add Dota2 games into the application settings using the AFR mode can enable dual-graphics Crossfire after entering the game, but the game screen keeps flashing not function properly. This problem has troubled me for a long long time, I beg you to help me to solve this problem, thanks again!If you can help me solve, and I hope you will contact me, my email: li20030207@qq.com

As Undying said, it's a DirectX9 game, so it won't run on both graphics cards, Crossfire is impossible. But I have a tip for you: Upgrade your RAM to 2x4 GB Dual Channel RAM, it will double your GPU performance, especially in DX9 games.
