Here :
PCI\VEN_1002&DEV_9874&SUBSYS_1E311002&REV_E3I think it is the problem,
I've just force manual installation (i've choose manually drivers folder, "AMD Radeon R7 Graphics") and that's work.
CRT Emu Driver installed and detected by Vmmaker...but I've strange slowdown's feeling when I move windows
Also in opengl apps (like retroarch), I notice slowdowns (It's better if I choose direct3d driver in).
In groovymame it's ok (d3d9) but there's also some very litte slowdowns.
Perhaps it's caused by my manual/partial installation ? Or CRT EmuDrivers based version (CRIMSON 16.2.1) is too old for good performance with APU R7 ?
When i try "normal" drivers, it's ok
In all cases, I can wait next version don't worry !
