.I have win 8.1 professional edition x64 a Samsung 4k TV and I tested an R9 Fury X card from a friend with windows drivers catalyst(not from site).Driver from windows version is july 04 2014.With old driver catalyst from windows its amazing,gorgeus...the image is crisp and clear.if I upgrade to latest crimson version the image is not so clear like with old catalyst driver.
I swear I will never understand why always automatically driver from microsoft windows are much better than latest driver from official AMD site.it s a conspiracy,or im crazy??
the bad things is with this nice old catalyst driver I can't start the game Wolfenstein 2-The new Colossus because he need vulkan1.dll......and he forced me to upgrade to latest crimson version to run it
p.s.I know when I was a child, Ati radeon are much much much better than green camp on TV OUT.On tv out ati radeon are the best,but crimson driver is not good.I think old catalyst are much better.
