5336 + 2.6.3 = movie perfomace lost

[Hannibal]

When i play movie under 2.6.3 i have significant performace lost. With 2.4.24 kernel X take 0-5% CPU but with 2.6.3 this is 55%-60% !!! (tested with xine). I cause 25% frame drop. With mplayer is even worse. Sound run OK but video is very slow. Strange is that mplayer say that everything is OK (A-V is ~ 0.000 !!!).

I try diffrent kelnel and X config - with no change, with one exception. When i change driver to nv movies run OK (25-30% CPU) but this is no solution.

Video card: GF2 MX400 64MB
Driver: 5336
Distro: Slackware-current
Bios: 03.11.01.30.00
Processor: Celeron 466@525
Motherboard: FIC VB601V (VIA Apollo PRO 133 chipset)
Glxgears: ~745 (both 2.4.24 and 2.6.3)

I bet you're using KDE...
your low frame rate is because arts does not work properly with the new sound drivers.
look at kcontrolcenter->sound&multimedia->general, disable arts' realtime priority and set it's auto-suspend time lower ( something like 5 seconds seems good to me )

Yes I'm using KDE, but I run test with alsa. I set auto-suspend to 1s long time ago.

A little update. I also noticed OpenGL slowdown. With xmms gl spectrum analyzer I have at most 2-5 fps under 2.6.3. Under 2.4.24 it run smooth so it was at least 15 fps (sorry but it hasn't fps counter ).

I think, there is problem with moving data between main memory and video card.

Good afternoon,

Is AGP enabled? If yes, how so? (through Kernel Agpgart or NVAGP).
SBA and FW?
Are you certain OGL acceleration is working (glxgears, NWN, tux)

Thank you for your time,
Frank Russo

This same "files" i have with 2.4.24.

And I'm sure OGL is working (glxgears).
