Wow, cool. The cards reasonably priced too. I might have to try this out. My release 360 needs a boost.

$200 for the capture card... wouldn't it be cheaper and easier to just buy the game for your PC??

If you can find me a place where I can buy Uncharted or God of War 3 for PC then sure!

Didn't both Uncharted 2 and GoW3 use some kind of msaa?
anyways
If it's working good then i really don't mind paying for such a capture card. I got my consoles connected to my 24" computer display so i dont sit very far away from it, the aliasing is rather annoying in most console games.

Let me get this - with this software, I can use my pc gpu to give a boost to my ps360 through a capture card?

U2 2xMSAA and GoW3 MLAA. ;)

Yes sir :)
FXAA is a post process AA filter designed primarily to reduce aliasing in differed rendering engines where msaa isn't compatible.

Having used it a lot in Age of Conan I think its pretty darn nice filter with a very small performance hit (less then 2x msaa) while still looking pretty good.

EDIT: HardOCP did a nice analysis of fxaa recently and compare it with the equivalence from Ati. It's some good read linky

This is done while playing? Or after capturing footage? I mean is it done live or is it like an effect I add to a video file.

It is done in real-time because i am hypothersizing that the software applies the FXAA algorithm over the streamed image much in the same way ATI implementation of MLAA works on their GFX cards though FXAA maybe more forgiving on HUD elements.

While the ATI technique is done at a driver level and the 2D image is analysed and processed, it is the same with the Capture card FXAA method. The 2D image is analysed and processed in real-time and again i am hypothersizing that that is how it is done on games that support FXAA natively (Duke Forever, Age of Conan, Hamilton's Great Adventure).

EDIT: Beat me to it

it's real time while playing like a real time post process effect directly on the captured stream.
Kinda what you can do with media player classic or vlc by adding various effects in real time.

nvidia FXAA is very similar to Ati's MLAA but fxaa is universal and works on both brands :)
It's a real time single pass shader compatible with both cards using edge detection algorithms. In the HardOCS article there's a link to nvidias whitepage in pdf format about fxaa and how it works.

fxaa cant really see any difference between geometry, it treats the entire picture softening aliased edges, but it works pretty well in the games i've seen it :)

with nvidia inspector you can force fxaa on a driver level, but it only affects open gl so far.
I've tried it with some old gl games and dolphin emulator using the open gl render path.
I like it a lot there as you get the added bonus of transparency anti aliasing for "free"

Sort of related even if it is a PC game :o

[OT]If you want a very good example of FXAA (for the curious) then try Hamilton's Great Adventure and you can find the demo and game details here. You need DX11 software installed and a minimum DX10 class hardware to run. Also your sound cards sample rate must be set at 48khz or you will not get any sound.

Any ways, the game is gorgious and the AA exteremly smooth without the ugly blur. At some point i was convinced that the game was using some sort of super-sampling technique (like Trine) until i chanced on the nature of FXAA and looked closely at the game GFX settings.

Anyway give the game a go. This is the sort of last resort AA i certainly would like in my games.[/OT]
