I'm running a gigabyte R9 380 (yay black friday/cyber monday deals)
Driver Packaging Version
on Win10 x64.
I recently upgraded to the R9 380 from dual 6850s, and thus opted to give Crimson a try, up from Catalyst.
One of the main reasons I always opt for Radeon chips is because of the desktop color management controls (I'm a digital artist, this is important to the trade).
Crimson still relies on the CCC.exe for it's color management, and even though I save the color settings, these settings are not applied on boot as they did in Catalyst.
"Display Color" settings under individual monitor drop-down menus are preserved, but "Desktop Color" is only applied when CCC.exe is ran (ie, manually accessing Radeon Additional Settings from right-clicking at the desktop).
Right now I've manually put CCC.exe into the startup folder and in the startup registry as a work-around (or sometimes just manually open the .exe), but hopefully this will be fixed in the next release (or just a total overhaul to move all remaining elements of CCC.exe over to Crimson).
