How can I get my PC to show graphics on GPU work?

The short answer is : you can't.

I used to think that might be the case but, it doesn't seem to explain why I can run very intense GPU based graphics games. I can also set several CPUs to run Seti data and get the BOINC output graphics screens - which are processed through the GPUs- so, GPU reserve capacity just doesn't seem to make a sensible answer. Ultimately the CPU through the OS controls and distributes my PC work. It would likely just be that BOINC is short on that end of the stick or there is a trick I don't know about with the BOINC config.

Someone with more technical knowledge could give you a better explanation, but AFAIK, only the CPU apps have the code to run the screensaver. I know it has been specifically excluded in all the "optimized" apps, including the ones for CPU, to make the programs more efficient. I believe the screensaver is an openGL program, and the CUDA (GPU) programs don't leave enough overhead. But as I said, I'm just a "user". (g)

The other reason is the CUDA apps do not include the graphics app like CPU stock apps do.

No, that's not true. It was always believed that using the GPU and making it show intricate 3D OpenGL graphics at the same time would increase the error rate, but it shouldn't. CUDA has had the capability to show graphics while doing calculations from day one, but the project just didn't choose to use the option.

Einstein does have a graphics app for the CUDA and OpenCL applications, showing it's well possible.
