How do you use one or the other graphics ON A PER APPLICATION BASIS "with provider stuff the latest X server"?

On a desktop however, you shouldn't be buying an IGP system if you need a fast GPU anyways. The fast GPUs have made huge strides in idle power consumption every generation, at least for AMD's GPUs. Nvidia's not so much...

It's a weird thing, I know, but even CUDA and OpenCL on discrete cards do a much worse job at that. So when you're going to encode video, you should use the integrated graphics, not the discrete ones.

In windows if you are using the discrete card as primary card (which most people do), you can not use Intel Quick Sync without LucidVirtu enabled.
About LucidVirtu, I read reviews with pros and cons, but in general there are more pros.
About QuickSync, you don't get the best quality of encoding, but a good speed. And some people may be more interested in speed than quality. I do not mean you get a bad quality, I mean maybe it's better to use another encoder if you are looking for the best quality, from what I've read.
Some of the links below are tests with little old versions of intel and Lucid, but you get the point:
We look at Lucid Virtu MVP; a big technology for the upcoming Ivy Bridge platform due later this month. Is it any good, though?
HotHardware takes a look at Lucid's Virtu software which enabled Intel's Sandy Bridge Quick Sync technology when used in conjunction with a discrete

Like running XBMC seat on it.
But yes, you should not waste your money if you are not going to use it.

I've been using QuickSync extensively and I can attest that with most encodings the difference will be invisible to the naked eye.
