hello my friends , i have this problem, first of all this is the hardware that i have :
amd a8 6600k with integrated graphics hd8570d and a gpu shappire ati hd 7750 1gb
i was using driver crimson 16.2.1 ( beta), the last version for my apu a8 (considered legacy) , and i have enabled the option of dual graphics ( or hybrid crossfirex with the hd 7750 ) , i had a windows problem so i had to re-install it.
i made a fresh installation of windows 10 64 bits , and windows update install me the version 16.9.2 of crimson software automatically, so when i open the board of crimson program , i noted that my dual graphics option was missed ,the crimson only recognize the hd 7750 , so i need your help to do a correct downgrade of crimson driver from version 16.9.2 to 16.2.1 ( is the latest version for my apu ). thank my friends and sorry for my english , i'm from argentina !!!
