Directx not available - high CPU - client machine

[wodger]

Just installed 2.2.6 on server and client. Got the 'directx is not available' message on the server, reinstalled directx over the top of itself and tested OK.

The client is an old Lenovo A50 thinkstation with an Intel graphics card embedded. It runs GBPVR and NPVR fine and plays TS files fine. But NPVR has always shown this message about directx and runs at about 30% CPU all the time. If I open settings and leave NPVR in the background, it drops to almost 0% CPU. I have tried changing the UI resolution, reinstalling directx and reinstalling the graphics drivers (saw that worked for someone else), but no change.

I saw that this new version of NPVR was to have a fix for the high CPU problem where directx was not available but it doesn't seem to be working on this client.

Any thoughts?
Cheers

After changing the video renderer (different thread) this problem still exists. Seeing about 30/70% CPU usage when doing nothing/playing a recording. It works fine, even though it's such a slow computer, but I'm worried about the fan/processor health - the computer is up high in a wardrobe!

See if this helps.

Awesome, looks like that has done the trick.

Hi.
Can you look in to your NPVR.log if you have this crash ? It is a common problem of Intel iGPUs.

Code:

Yep. Any way to fix it?

well, only SUB can...

Can you guys see if this patch helps? It will hopefully help on cards that dont support hardware vertext processing.

I have Intel iGPU at work, so i will test it on monday.

Thanks Sub, it works for me! DirectX working on an Intel 82945G graphics chip for the first time.
