I had been using my FirePro V4800 for 4 years already and I'm still happy I got it once with my Fujitsu workstation.
But I got an issue with my FirePro V4800 and Lightroom CC 2015 (any version):
with the original driver (15.201.1151.1008) I get all the photos (either RAW or JPEG) looking as WB switched to very warm. It could be solved in Develop mode by switching on the Graphics Acceleration option, but it doesn't help in Library mode. Using latest and beta versions of unified drivers can't help even in Develop mode.
How could it be solved?
It was a problem of Windows profile for monitor. Creating a new one return everything for normal view.
