high cpu usage

[steveum]

I have noticed that when I have NPVR running and it is just showing menus, it has a rather high cpu usage for just showing a static image. Once I start playing a video, the usage goes way down. I don't recall GBPVR behaving this way. Is this normal or is there something incorrectly configured on my computer. I am running Windows 7.

Any particular screen? When I leave it sitting at the menu I'm seeing near zero CPU usage.

Post your npvr.log though, and I'll check you definitely have the direct3d components required. If you dont, it'll still work, but log an error and use a lot more CPU.

I looked at your logs from one of your previous posts, and it indicated you didnt have the direct3d components installed, and everything was being rendered in software:

Thanks. That fixed it.

I also get high cpu usage, because of an DirectX error:

I get the error on both WinXP with SP3 and Win7 with or without SP1. I have installed every DirectX-runtime etc that I could fine. The old version 1.4.7 didn't give me a problem, but 2.0.3 (and also 1.5.36) gives me a very high cpu usage on NextPVR.exe, even when the program is doing nothing at all.

With that error, you're going to get high CPU usage.

Did you install this: http://www.microsoft.com/downloads/en/de...laylang=en

[striben]

Yes, I installed it many times, and now once again, just to be sure :-)
But I also notice, that the error from steveum was a "not found" error. The error I get is an "invalid call".

Sorry, I'm not sure what to suggest then. I'm not really an expert in the various versions of Direct3D. That link I provided was for the specific version that done the job for just about everybody else.

I have this error too here, but i have only stupid Intel Atom with intel GPU here. Home i have ATI GPUs and there is no problem.
Can i ask what GPU do you have?
