High CPU Usage / no VMR9 available

[jksmurf]

I'm using Pure Video v1.02.196 and things are OK. I'm getting CPU of 25-35% varying as I use the PC for web browsing, etc.
I have a GF FX5200 AGP installed. CPU is Athlon XP 1800+.

I AM using the 81.98 WHQL drivers, though because I ran into an issue with newer Forceware drivers, but Pure Video v1.02.196 is working without sapping my CPU.

I'll remember this, though and won't go up any further in my Pure Video.

Very interesting thread, thanks SD, I must see what the effect is with a drop back with the drivers. I have a similar setup to Talcum, I'm using Pure Video v1.02.196 and Forceware 91.28 (beta) but things are OK. I haven't checked CPU usage I must admit, but no problems for me, although when comskip runs it maxes out. I have a GF FX5200 AGP installed. CPU is PIII Celeron 1.2GHz. I can run VMR9 (it would seem, no problems checking it in GBPVR).

[EDIT] So where do I find the older WHQL Forceware and PureVideo Drivers?

Thank you =)

But remember: If you're downgrading the ForceWare to the "good" 81.98 WHQL, then you have to downgrade PureVide too to 1.02.185.

You'll find it on the FTP of NVIDIA. ftp://download.nvidia.com/Windows/dvd_de...02-185.exe

You too say, that you can use VMR with your drivers. So i think that you don't use DxVA. I am not sure about this, but i think even the GeForce FX is capable to use DxVA. It's worth a try.

Cheers SD,

Sorry if this is really dumb Q, but how do I know if I am actually "using" DxVA (as opposed to just having it installed)?
[EDIT] btw (out of interest) how did you figure out which ones worked and which not? Did you just keep going back and back with the combinations of driver versions and PureVideo until you worked out which pair was NOT giving you HA when using DxVA?

Here you can see, how it can look with DxVA enabled, ForceWare >= 81.98 WHQL, PureVideo 1.02.196 and VMR9 watching TV. My german sentences there aren't important. Just look the Screenshots.

That has absolutely NOTHING to do with anything like dumb. Because you're asking, i think that you dind't done the following steps:

1. Install ForceWare like the 81.98 WHQL
2. Upgrade to Windows Media Player 10
3. Update for Windows Media Digital Rights Management-enabled players
4. Update to enable DirectX Video Acceleration (DXVA) of Windows Media Video content in Windows Media Player 10
5. Install NVIDIA PureVideo Decoder 1.02.185

You know... i am a silly one. Because i am using my PC not alone for GB PVR i am updating drivers/codecs and other stuff regulary. But some day i discovered, that my VMR9 didn't work anymore (i told sub that gb-pvr was buggy ), but GB-PVR wasn't responsible for this.

So i tested many combinations myself and with other people in german PC Forums. So we could find out, that especially the ForceWare >= 81.98 WHQL and the latest PureVideo 1.02.195 isn't really useful for GPU's on AGP Basis and for PCIe Cards smaller then the 7xxx Series.

We could determine that the combination 81.98 WHQL and PureVideo 1.02.196 didn't work right together; PureVideo 1.02.196 needs at minimum ForceWare 84.21 to work fully correct with all available options.

Hmmm ...I certainly don't have THAT problem (in your link) with my current (beta) NForce and PureVideo Drivers, viewing on the PC. if you are correct, then maybe DxVA is really NOT installed or enabled.:confused:

However what is odd is that when I looked in the PureVideo Decoder settings it says "Hardware Acceleration" (checked) and DirectX VA mode A (idct). The picture (on the PC) is fine and CPU is around 60%. (Would attach jpg, but I looked at the the PC at home using UltraVNC ... can't take a screen cap remotely with Irfanview, ctrl-alt-f11 doesn't seem to work with UltraVNC..)

Theoretically, if I install/it and enable it with my current driver combo, I should be able to reproduce your problem.

and DirectX VA mode A (idct).

This means the decoder/renderer/video-card are using DXVA.

To prove this, try unticking Hardware Acceleration and save and exit/restart your playback (eg liveTV), and see if your CPU utilisation changes.

Well, I got a Geforce 6200 (128M, 64bit) and am very happy with the picture, which is noticeably better than my FX5200.

However I still get the same relatively minor, but noticeable and very regular stutter every 8 to 10 seconds. If I watch the Purevideo details tab, I see it drops about 4~5 frames at these regular 5~10s intervals

So an improvement in one area, not so in an another. Yes, I have been through the quartz.dll 9B/C swap, tried various decoders, all of which are reasonably similar, none of which gets rid of that stutter. I do not have FFDSHOW installed (tried that).

My first reaction was must be my weak (1.2GHz Celeron) CPU. But I see others with much faster CPU's with similar issues and except when it's doing a comskip, CPU usage isn't that bad. 512MB Ram is OK, I think.
So what should I check next? BAD RAM? Slow Hard Disk Subsystem?

I am using the combo of Nvidia Geforce and Purevideo drivers mentioned in this thread but I see that there is a PureVidep Update: ftp://download.nvidia.com/Windows/dvd_decoder/1.02-223/
the Forceware Beta Drivers http://www.nzone.com/object/nzone_downlo...91.33.html also mentioned "New NVIDIA PureVideo features and enhancements"

Not sure what that entails, but might give it a whirl anyway ...:-)

Can you reproduce and post your gbpvr.exe-native.log so we can check there is no unexpected problem directshow filters? (like Retime)

Here you go.
