Crytek on Async Compute: Interesting, But It Adds Non-Trivial Complexity; DX12 Suppor

I think it will take a bit of time, and the drivers & games need to mature and do the right things.
Just reaching parity with DX11 is a lot of work. 50% performance from CPU is possible, but it depends a lot on your game, the driver, and how well they work together.
Improving performance by 20% when GPU bound will be very hard, especially when you have a DX11 driver team trying to improve performance on platform as well.
It’s worth mentioning we did only a straight port, once we start using some of the new features of dx12, it will open up a lot of new possibilities – and then the gains will definitely be possible.
We probably won’t start on those features until we can ditch DX11, since a lot of them require fundamental changes to our render code.
DX12 includes new hardware features, which I think over time will make it possible for us to make games run even better.
The gist of it is that DirectX 12 may end up delivering that 20% performance boost claimed by Microsoft, but only in due time, once game developers have been able to learn how to harness it properly.
Of course, in the meantime we’ll keep track of how all the DirectX 12 enabled games are doing, so stay tuned.
