Essex innit!

It seriously makes edges look so much smoother and comes at a fraction of frame hits compared to MSAA. With it being a new design, I can only see this getting better and better the more it is tried and tested.


The Secret World looks a good game to me. Anyone played this?
 
I love it. I use it on Assassins Creed 3 and I have to say, it's the best anti-jaggy out there with the least performance hit. I will always prefer MSAA, and will take the hit in performance for it and I never liked FXAA for the blurriness it creates however TXAA does a mighty fine job in the balance between blurry and smooth.

If the image is larger than 1280 pixels wide then please resize, link only or put in spoiler tags. Thank you.

How does this differ from things like SweetFX or other FXAA/post process injectors?

TXAA is a combination of hardware anti-aliasing, a custom anti-aliasing resolve, and a temporal filter. To filter pixels, TXAA uses a contribution of samples both inside and outside of the pixel in conjunction with samples from prior frames, to offer the highest quality filtering possible. In motion, TXAA approaches the quality of other high end, professional anti-aliasing algorithms, though the higher quality filtering used by TXAA does result in a softer image compared to the lower quality filtering of traditional MSAA.

FXAA isn't a true form of AA and basicaly TXAA is Nvidias, much like MLAA is AMD's. It is stated that 4*TXAA is superior to 8*MSAA and costs less than 4*MSAA. Time will tell if it lives up to the hype. Not too many games mentioned using it but it will be part of the Unreal Engine 4, so that can only be a good thing.

It sounds like it's a combination of the old temporal anti-aliasing, traditional MSAA and FXAA.

What's interesting is that if it is a derivative of temporal anti-aliasing, it'll only be effective beyond a certain frame rate.

It is better in motion, as it does it over multiple frames instead of blowing it on ultra high resolutions. I guess on a still image, it may not look so good. I am not sure on it needing a certain fps to achieve but quite possible.

Edit:

Looking at Illuz's image, it does look pretty jaggy free. Could you get one with more buildings please?
 
TXAA was one of the exciting developments up and coming. Good to see it implemented in a strong AAA title.

I like MSAA but the performance/VRAM requirements in some games are absurdly disproportionate whether you have the power or not.

I'll go grab some now mate !
 
Great shots and the game does look good from those images. I will have to put this on my birthday wish list for next Saturday :)

Very impressive VRAM usage btw.

The images do look good. From what I remember, temporal AA does indeed look better/more effective in actual motion.
 
Yeah, it's very fluid and smooth. I love the game. It also takes up NO VRAM at all also which is remarkable for the detail in the graphics.

Check the screen shot thread for pics of hitman, which is the best visual game out this year imo.
 
Only thing I don't like is that it blurs alpha masked textures more than is diserable as can be seen on the wire mesh on the boxes on the secret world video. It is impressive how well it stabalises the overall image tho.

EDIT: Also do love the use of tessellation to model dynamic snow surfaces in assassins creed.

lol Tommy. Respect your elders in future then :D and thanks :)

@ Imginy, I am not sure if it will be in BF4 but Crytek have it onboard I believe. Hopefully we will see it in Crysis 3 :)
