Question about LPV

We’re checking in changes incrementally to the main branch. The first execution of rendering work on other cores will be in the upcoming 4.4, but this is just one of the first steps and has a bunch of sync points which will be removed later.

We’re taking a data-parallel approach so it will scale to however many cores are available to the task graph system, which is typically NumPhysicalCores - 2, since the Game Thread and Rendering Thread get dedicated cores assigned.

Sadly PC will not see huge improvements from this effort, because of the way D3D11 was designed. There’s a video driver thread in the background that will quickly become the bottleneck for rendering many objects as we lower our renderer’s single threaded duration. This is one of the main things Microsoft is hoping to address in the upcoming D3D12.

I take it no Mantle plans then? Guess I don’t blame you, a one platform, one GPU only re-write wouldn’t be the most time efficient thing in the world; though you are using Metal for the newer iphones yes?

As for distance field AO, it looks surprisingly nice! Some directionality would be greatly appreciated, but I’m not sure how you’d do that.
