I bought couple of months ago Lenovo Y40-80 laptop with 16 GB RAM, i7-5500U, 512 GB SSD, AMD Radeon R9 M275 4GB. I wanted to replace my 4 years old desktop for video editing (Adobe Premiere Pro CC), but this did not work well because of the Radeon video card. AMD Catalyst Control Center refuses to use the video card for video editing and even for the video play in applications like VLC and Media Player Classic?! All these applications are locked in Power Saving mode. Today I downloaded the latest beta version of the Catalyst 14.502 from May 26 2015, still the same thing.
Why would I need a (relatively powerful) graphics card if I cannot do video editing? This card is supposed to be on par with 7770, in my desktop I had 7750 that worked decent enough. The play in Adobe Premiere Pro stutters with R9 M275 (probably because I am left with the Intel integrated video on i7-5500U) which makes editing impossible.
