Yeah, the problem was making sure we didn't have screen tearing. T he only path to video was through the mobile integrated graphics interface even when using the external graphics chip. On a desktop CPU you can DMA into graphics memory directly and get the frame sync.
I think you have to do this if you want to be able to switch between integrated and external. Which we didn't care about but perhaps most people do?

Most people need to be able to power down the discrete GPU when they're done gaming in order to have reasonable battery life, and the most user-friendly way to make that possible is for every application but the video game to use the integrated GPU.
