- p1necone 6y agoThey basically render frames on the video port-less GPU, and then pass them over to a second GPU for actual output. So probably quite similar to what Looking Glass is doing.
- Teknoman117 6y agoSort of. It's the exact same thing as Nvidia optimus. Linux calls it DRI-PRIME or PRIME offload. Get it =P ? Big, display-less GPU renders frame, image is copied into VRAM of smaller GPU with a display. Smaller GPU draws image to screen. Most of the gamer laptops do this. There's no physical link between the display and the big GPU. I believe the mobile cards enable a second DMA engine that is usually soft locked on GeForce to handle the transfer.
