Nick Penwarden - VP of engineering, Epic píše:"So, when GPU load gets high we can lower the screen resolution a bit and then we can adapt to that. In the demo we actually did use dynamic resolution, although it ends up rendering at about 1440p most of the time."

With this system, developers won't have to bake in lighting into their game world nor have to look at computationally expensive techniques such as ray tracing to simulate bounce-light for GI, as the game engine dynamically does this things for them at a reduced cost compared to RT.

Epic nikde v souvislosti s Lumen, tak se to totiz jmenuje, o RT nic nerika a nepise. Lumen je s RT dany do protikladu

Asi tezko dam RT do protikladu s RT. Digital Foundry to same. Najdi mi jasny oficialni zdroj, ze Lumen je raytracing a ne "fake tracing"

"Lumen uses ray tracing to solve indirect lighting, but not triangle ray tracing," explains Daniel Wright, technical director of graphics at Epic. "Lumen traces rays against a scene representation consisting of signed distance fields, voxels and height fields. As a result, it requires no special ray tracing hardware."

To achieve fully dynamic real-time GI, Lumen has a specific hierarchy. "Lumen uses a combination of different techniques to efficiently trace rays," continues Wright. "Screen-space traces handle tiny details, mesh signed distance field traces handle medium-scale light transfer and voxel traces handle large scale light transfer."

• Až 4 Ray operations za takt na CU

• Max. 380 "GigaRays" na Box a max. 95 "GigaRays" na triangle
• Celkový výkon zavisí na propustnosti, počtu ray intersection nodů
• BVH běží paralelně se shader operacemi
• Akcelerace 3 - 10x (oproti non HWRT hardwaru) při minimálních nárocích na plochu
