Sorry for my bad English..
Will Radeon Crimson edition support dual graphics system in the future? I meant unlike the amd catalyst one, specific apu must with specific gpu, something like a10-6800k is able to dual graphics with r7250x.... Do you think it's possible in the future?
Dual graphics should be supported in the Crimson 15.12 WHQL driver, you can download it here. The option for dual graphics appears under the Display > Additional Settings option in Radeon Settings. Click Additional Settings will bring up CCC Slim, which should contain the option to enable/disable the feature. However we still recommend certain configurations as mentioned here, so we cannot guarantee that using a different configuration will work correctly.
