Direct compute I think is part of Direct X so on a PS4 might not be likely.

Do we even know the GPU architecture? obviously natively it supports botbut which one have they choose, wasn't the PSX Direct X?

Err what proves this exactly? What have i missed?

Read the op dude, I thought you was a dev lol

you do realise these guys aren't talking
Specifically about the ps4 gpu right?

If you would have game with Nalu quality hair on Ps360, you would have to use less computing power and memory for everything else in the game.
Meaning not so good sub surface scattering approximation for a skin, degration of general polycounts and physics for the rest of the scene.

But that wouldn't be a problem for say TR2 on PS4?

Yes, but i was strictly talking characters. Ofc giving up on overall look and performance of the game wasn't feasible in the ps3 era just to get decent hair, but in PS4 era this shouldn't be a problem. I'd rather they have a bit less physics overall in the scene but add realistic looking hair. I'm curious to see how AMD's tressfx will look in tomb raider, in motion i mean. If it looks good, for me, that's more impressive than quite a bit of stuff from the Sony conference (games wise).

Agni's Philosophy hair trumps this hands down.

Actually Agnis hair is a midpoint between old method and a new one.
It uses polygon strips with texture to create volume and single strands for fine detail.

The tressfx and old nvidia demos w/are a more performance intensive.

Yeah Agni blends old 'flat planes' with individual strands and looks pretty great. The beard physics is where its at
