Have you tried gaming while simply letting the GPU crunch? I know it will not always work well, but for some games (e.g. Civ V) I really don't mind it. In fact I feel less guilty for "wasting" my time with that if at least the GPU continues to do so real work ;)

And regarding your question: there should be some <exclude_GPU>number</exclude_GPU> tag, but I don't know the details.

I haven't tried yet but would like to implement two separate BOINCs on my main desktop machine if possible. I play games on it during which the BOINC manager will auto-idle, but games only need the primary GPU's resources and there's no need to idle the second GPU along with it. If this is tricky to do, is there a guide/tutorial anywhere?

I have been able to get two clients running but it has been a while. Here is a thread over on the Test4Theory project that has some discussion about getting two clients to run at the same time. Be sure to read all the way through the thread as there are suggestions offered throughout.

Also, here is a post over at WCG that I put together for Ubuntu. Windows is a bit different, but maybe this will help.

Obviously, you will have to put some parameters in the cc_config.xml file for each BOINC client to tell it which GPU to exclude.

In Windows, in the BOINC Manager you can click on "Advanced", "Launch another BOINC Manager" and have multiple BOINC managers running at the same time. When you start the second BOINC manager, you can attach to BOINC client #2 and be able to control both clients at the same time.

If you get through all this and are still having trouble, let us know and I will try to help.

Disclaimer: I had this working for WCG and Test4Theory. I can't remember ever trying it with multiple gpu's on the gpugrid project. If you have trouble with that aspect, let me know and I will do some testing.

Hope that helps.

There is another way to do this.
Create two cc_config files in two different directories, one to disable GPU 0 and the other to enable GPU 0 again, and have two batch files on your desktop; one to disable GPU 0 in Boinc prior to gaming and the other to enable it again. Just double-click on the 'DisableGPU0' batch file to disable GPU0 prior to gaming and double-click 'EnableGPU0' to enable it afterwards.
