    R7 M265 performance is lower than with built in Intel card on ubuntu 14.04 with ATI drivers installed

    vazia

      I have a laptop Dell Inspiron 7548 with built in Intel graphics card and ATI Radeon R7 M265 with Ubuntu 14.04

       

      vasyl@insp7548:~$ lspci -v | grep "VGA" -A 12

      I've tried to install native ATI drivers from the website as well as from fglrx-updates. But in both cases my R7 card shown worst performance in games and during regular laptop usage like playing video, browsing then built in Intel card. I switched cards in Catalyst before testing.

       

      UPD: Here are system details after I switched graphic card to Radeon in Catalyst :
