Why would they use RTX when they could use DXRays and have it run on both Nvidia and AMD. AMD can already do raytracing thanks to GCN (Vega has more compute than 1080 Ti). I wouldn’t expect raytracing until the 1809 update is on the mainstream Windows update (I haven’t got it yet, is this just me? I’m not updating as an “insider”?)
They’ll probably also have some kind of filter hardware like Nvidia has on Navi as well.
I’d be more excited to get DX12/ compute based gameworks integration and some form of VXGI into mainstream. VXGI shadows and reflections look almost as good as RTX and costs less than half the compute resources, and the DX12 based gameworks are agnostic as well.
Maybe I’m just a victim of old AMD market hype but I’m still depressed that Intel and AMD IGPs aren’t used for accelerating world (as opposed to screen) space physics, maybe some stuff that Niagra does can be accelerated here if it sees it available. Intel would love you for it too, given the 9900k will have a DX12 IGP, and maybe the r3 2400g wouldn’t be so *****.
DX12 was supposed to make Heterogenious Compute a thing for simulation sided workloads, and I’d love to see an R7 2700GX or something with at least the same Vega 11 as the 2400G.
