same thing... I'm verry hungry, i've buy vega for 3D perf and Adobe... But there are no compatibility under C4D R19 and CC ...
So, i've trying windows7, but gpu acceleration not working, and i've try windows 8, but amd doesn't give the drivers....
Do something AMD please ...
Reproduced the reported problem internally, Logged the internal defect SWDEV-136328 will be fixed in future releases.
This is a limitation from Illustrator itself, which turns off graphics accelleration on win7 if AMD card is detected
See the system requirements from adobe website
You can work on win8.1 (win 8 is not supported anymore) or win10
We are working with adobe to understand why they impose that limitation
