I have got a big problem with my A8 5600k and HD 6670 1 GB DDR3 (gigabyte) vga card.
I enabled the dual graphics mode, in "AMD vision engine control center" but doesn't work.
I have tried with a lot of new games, with and without APU, but i've gots more fps without APU, why? The OP system: Win7 x64. The latest vga driver: 13.2 beta. ( I first try with 13.1 driver, but cannot work).
Battlefield 3: (Dual Graphics enabled)
Resolution: 1024x768 75 hz
15-18 fps, and lag!
Without APU: (1024x768 75 Hz) high settings, 31-35 fps, and smoothly!
F1 2012: (dual graphics enabled)
Everything on Ultra.
FPS: 15-22 (and lag!)
Without APU (alone HD 6670) 25-30 fps and smoothly!
Assassins Creed 3. (Dual Graphics enabled)
Resolution (1024x768 75 hz)
max settings out, 8-10 fps it can't playable.
Without APU: (1024x768 75hz), 25-35 FPS!
I hope you can help me and solve my problem.
I look forward to your reply.
