During this year’s SIGGRAPH, Intel showcased the latest API of Microsoft, DX12. Intel’s demo is perhaps the first public demo of DX12 (well, if we exclude the Forza 5 demo) and what’s interesting here is that the performance difference between DX11 and DX12 is around 50% on a Surface Pro 3 tablet.
As Developer-Tech noted, Intel’s demo rendered an asteroid field with 50,000 unique asteroids in it which equates to 50,000 draws per frame:
“Each asteroid is unique through procedurally-generating a combination of vertices, textures, and constants. To show the improvements, the demo is able to switch between DirectX 11 and 12 at the press of a button whilst locking the frame rate to keep the GPU workload constant.”
This demo was running with 19fps on DX11 and with 33fps on DX12. That’s almost a 50% difference, showing off the performance gains that PC owners should expect from this new API (provided they are CPU limited).
DX12 targets Holiday 2015, so don’t expect to see games taking advantage of it anytime soon.

While he is a die-hard PC gamer, his gaming roots can be found on consoles. John loved – and still does – the 16-bit consoles, and considers SNES to be one of the best consoles. Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2. John has also written a higher degree thesis on the “The Evolution of PC graphics cards.”
