JUST CAUSE 3 DIRECTX 12 DRIVERS

I think DirectX 12 is going to show some nice gains for AMD with its more parallel/asynchronous focused approach.

JUST CAUSE 3 DIRECTX 12 DRIVERS

Looks like it's not even available in Nvidia drivers yet

So currently none of this is utilized, but it is an area of interest and we'll see what's possible down the road. So if to save some processing you add latency to wait the result, you win nothing ! Currently, the Rift SDK is DX11 only, i made a hacky bridge to DX12, so technically you can do all the rendering in DX12, multi gpu and whatever and just copy the result to DX11 to make the Rift happy at the end, but a better integration for DX12 would help first, and second, without a better way for GPUs to communicate, it is hard to even get something from the SLI altogether ! The current problem with multi gpu rendering is not much about rendering things on several gpu, but the bridge between them, the pci express bus is very slow, and that's why nVidia Pascal is bringing to the party a new SLI bridge because right now, on a PCIe 3x, the transfer of an eye at the resolution of 1440x1560 ( 960x1080 * 1.5 for center texel to pixel match ) is 3ms ! It means at some point, you have a 3ms period of time the gpu 1 wait for the gpu 2 before it can apply the time warp and display to the rift ( only the gpu hook to the rift can do it ). It is not much about latency but to try to use every piece of hardware power at disposal.
