    Fall of the FPS 10-50 times after the driver installation (WITH VIDEO DEMONSTRATION)

    radeongamer

      For 2D mode, "Standard VGA Graphics Adapter" works 10-50 times faster, than the RADEON driver!

      This bug all new AMD cards (2014 - 2018 release) with RADEON Driver - from Catalyst v15.7 to RADEON Crimson v18.7.1 (all versions)

       

      Video demonstration this problem:

       

      Experiment #1:

       

      RADEON R7 360 with "Standard VGA Graphics Adapter" (without Radeon driver)

      Desktop: FPS = 800-860

      Viewing the Spectrum foobar2000:  FPS = 750-780

      Scaling in P-CAD:  FPS = 700-800

       

      Normal 2D performance!

       

      Experiment #2:

       

      RADEON R7 360 with Radeon driver v18.7.1

      Install driver - win7-32bit-radeon-software-adrenalin-edition-18.7.1-july12.exe

       

      Desktop:  FPS = 1280-1320

      Viewing the Spectrum foobar2000:  FPS =  27-54

      Scaling in P-CAD:  FPS = 10-1300

       

      Very low 2D performance!

       

      Resume: "Standard VGA Graphics Adapter" works 10-50 times faster, than the RADEON driver

      on 2D classic theme Windows 7. NVidia and Intel card there are no problems!

      Unfortunately, the bug low 2D performance is present on RADEON drivers only.
