WOW. They are saying a GTX Titan does  5 Teraflops now and it will do 20 extra Gflops per frame on this. 

Works across all Microsoft platforms. Awesome.

Example: DX 11, one core is doing most of the work on D3D12, over CPU utilization is down 50%

Note: That above is quite a dramatic improvement!

Improved multi-thread scalability!

WOOO! Forza 5 dev talking about the game being ported to d12. Took 4 man-months to port.

This seems all well and good.

Took 4 man months (people months?) to port Forza 5 to DX 12.

That's what they said. Going forward, all new games would just be developed in this framework of course.

So would you say they are saying a 20% to 50% improvement?

Looking like 20% GPU improvement, 50% CPU improvement.

Nvidia will support DC12 on Fermi, Kepler, Maxwell and forward.

Intel will support it at launch of Haswell.
