*spinoff* Naughty Dog and FXAA

[Ruskie]

I guess ND could use FXAA in UC3.Makes sense...Its cheaper and it has better stability than MLAA.Maybe they can polish it even more.

I integrated FXAA yesterday afternoon. Painless integration, impressive quality, AMAZING performance. @TimothyLottes is a
hero.

If you haven't at least evaluated FXAA (GPU anti-aliasing), drop everything and try it out NOW (it won't take long). tinyurl.com/lottesaa

Interesting, I hope IQ will be better than in current (E3) build

As long as FXAA doesn't lessen the contrast too much then it should be a nice addition to consoles.

Sounds good. If they can achieve good AA quality, ND can use the free SPU time for the elemental effects.

@Desmio You're putting words in my mouth! I work for a Sony central tech team, not directly on Uncharted; dunno what they use for AA.

So... it's not confirmed ND will use FXAA.

Yea,I wrote "I guess ND could use it",someone else said it like its a fact.

Yeah you'll probably have to talk directly to one of ND's own. Most that work for the other first party studios probably wouldn't be familiar with what's going on with their game either.

Honestly I don't know, better leave that one to the techie overlords here to discern.

How the hell could such a filter reduce contrast of the image?? That'd require modifying every pixel, or at least the majority, and no such tech does that...

Have you had a look at the source code for version 3?

The filter only modifies edge pixels. Other pixels are simply passed though. It doesn't modify color contrast.

If you are seeing contrast reduction, maybe you are passing color information to the filter in wrong color space (gamma/linear). There is an #ifdef for changing linear/gamma mode on PC.

Yeah, that's what I've meant, something that's basically a smarter edge blur filter shouldn't modify anything else on the image, otherwise it'd be destructive and basically wrong.

It can change contrast locally, sure - but that's something different and when we talk about the contrast in an image we generally mean the entire thing, all the pixels.
