ATI Catalyst 9.1 Drivers - VMR9 mode and DXVA acceleration no longer work (1 Viewer)

[zubovsergei]

I just installed ati catalyst 9.1 drivers on vista 64 bit system, and found that no movies were being displayed. I was using VMR9 mode with gaussian filtering. WHen I switched to EVR, it worked okay. The reason why I use VMR9 is that it gives me the smoothest playback. Now have to use EVR

I believe that the catalyst 9.1 drivers have some bug that antisotropic filtering no longer works or something to that effect. I wonder if that is what is messing up the VMR9 mode, although I tried using no filtering and still got no playback.

I had an issue similar to this when I went to 8.12. Make sure that AA and Anistropic filtering are set to application and see if that works.

I tried everything including setting filtering to use application settings, and VMR9 just won't work. Reverting back to 8.12 drivers fixes the problem but 9.1 forget it.

Same problem here too. But not sure if I want to go back to 8.12. OS is XP MCE 32 bit

In mine XP Professional SP3 9.1 works really nice, I'd say much better then previous version. Colours are better as well. I am using VMR9, can test EVR and see if that gives any problems.

Confirmed Catalyst 9.1 is the culprit. Rolled back to 8.12 and VMR9 works!!

I heard that 9.1 breaks DXVA acceleration, not going to touch it with a 10-foot pole.

Yes I believe it does break dxva acceleration. I had it working before 9.1, and now it uses CPU.

I never relied on dxva anyway, since I use coreavc, so it doesn't bother me. However, 9.1 does fix alot of games. Mirror's edge and burnout paradise are just two that run much smoother using 9.1.

Cannot confim this. Works nice here on XP32 and Vista32. Maybe it also depends on the graphic card in use.

yea 9.1 fixed my DXVA issue in XP Sp3 wasn't working but now it's working nicely
