Using a GPU and CPU client together halves one or the other?

[imaheadcase]

I was testing distributed.net GPU client yesterday, noticed when running the CPU client with it that the GPU scaled back to same speed as CPU working.

That a bandwidth thing or by design?

What's your CPU?

 

[imaheadcase]

Intel Quad core 2.83ghz

Set the GPU client to a little higher priority. Or the CPU client a little lower.

You don't want the GPU client to have to wait for the CPU cycles it needs.

What CPU cycles? It does not use any CPU when running on GPU core...

Oops, I was expecting d.net to be similar to F@H nvidia GPU client which uses 1-3% of a CPU "when running" and probably much more for the few seconds at start-up and when it finishes a WU and sends it in.

How does d.net GPU client do those things? Does it have its own operating system? What kind of video card has a LAN connector?

incorrect. the CPU has to set up the work for the GPU.

Yes but running it uses none, running both of them it does not show any CPU at all...

Folding or d.net.
