New anti-aliasing algorithm TXAA, Arma 3 potential?

[Sethos]

Adding TXAA shouldn't be hard or time consuming to implement, I don't see why anyone would mind just because they are on hardware that doesn't support it. Also, FXAA 4 is no longer in development, it has been cancelled due to the guy working on / with TXAA.

As for the argument above, TXAA needs to be implemented by the developers. There is no injector or setting in the Nvidia control panel to force it.

According to Nvidia Arma 3 won't necessarily have to support TXAA natively as you can enable the AA via the Nvidia control panel(driver) so theoretically you could have 0 AA in game and have Nvidia run TXAA. Although ideally this could be a possible feature as BIS are always looking for ways to balance visuals with performance.

In summary:

TXAA(1) = 16x MSAA = 2x MSAA performance tax

Subsequently this technology will be available on Kepler architecture AKA: Geforce 680GTX release 22nd March.

The Quality is very affective, I am liking this

Plus you could use Anti Aliasing Post Processing which helps blur the lines instead of geometrically fixing their aliasing.

in games it should be even better because it works in motion.

TXAA looks VERY promising, i hope it will be available in Arma 3. When it comes to AA i never use the in game way, always override it in the Nvidia CP to at least 4x AA.

Post processing means it just blurs the rendered frame in places of high contrast.
It's a poor man's AA for engines that cannot support proper measures.
If you compare the picture the difference is obvious and PP is a step back from normal AA we already have.

were does it say it's postprocessing?

[MavericK96]

From what I can tell, FXAA is sort of a hybrid of hardware AA and post-processing AA. That's just from reading through Timothy Lottes' blog, but I could be wrong.

Also, I would argue that PPAA is the future. MSAA/SSAA are "brute force" methods that look pretty good but are heavy hits on performance. I also agree that PPAA is not yet at a level to completely replace MSAA/SSAA, though, at least not in ArmA 2.

[Leon86]

yeah, it does a bit of msaa but it also uses info from previous frames for the best estimation of how a frame should look.

I'm not a big fxaa fan, but this txaa looks very interesting, too bad it's kepler only, I wonder why.

MSAA is woking fine now... not much performance lines and no horrendous white outlines (I really hate them...) So, aslong as there are now white outlines (damn you...) I probably wont mind TXAA is not implemented, could it be done after launch in some sort of patch?

Maybe I'm misunderstanding your post, but I get white outlines with MSAA in ArmA 2, which is generally why I hate having it on. But if I turn it off, SMAA Ultra is not good enough to get rid of jaggies/"crawling" so I lose either way.
