NVidia Anti-Aliasing Guide (updated)

well, according to this guy, it should also work without ingame MSAA...

 

Yeah I saw that, but the pictures don't show a comparison set of images for No MFAA, so they are all irrelevant unless we a baseline to compare against.

We could just be looking at standard MSAA for all we know in those shots.

 

TXAA is MSAA and FXAA combined.

 

Get 2x msaa on watch dogs (or any game that uses txaa) and then force FXAA on it via either sweetfx, or nividia inspector. The combination of 2x MSAA and fxaa won't be even a fraction of the quality of TXAA 2x. Same goes for 4x MSAA + fxaa vs TXAA 4x.

Txaa almost eliminates temporal aliasing, whereas fxaa and msaa in direct x 11 barely touch it. The shaders that txaa uses are very different, and the whole thing is designed to work as a multi-pass system.

It's like saying that HBAO+ and SSAO are the same because they are both technically ambient occlusion. Whereas they are very different and "think" in very different ways. For me the look of what TXAA achieves is closer to sparse grid supersampling 8x in direct x 9. Better than that even. MSAA and fxaa do complement eachother, however they are WAY different to TXAA in antialiasing functionality, have a look at the shaders if they ever release the code, i am willing to bet there is very little in common with smaa/fxaa for the post processing part of TXAA.

 

tnx for the hints bonk
but unfortunately it didn't worked, tested with aa fix on/off, even with different flags and no good results
ill keep using gedo then, the only problem is that my gtx770 cant handle 4k with AO @60fps :/

 

I haven't tried it. But given that GeDoSaTo is still involved, I doubt it will work. But I may give it a shot anyway.

DSFix worked when it came to this, but DSFix isn't GeDoSaTo.

This couldn't be farther from the truth.

I've talked about this before, but TXAA is not even REMOTELY like FXAA+MSAA.

MSAA+FXAA without downsampling is pretty horrible. As FXAA like SMAA, sometimes using these together will actually end up reverse anti aliasing some elements depending on the game

And since FXAA is simply edge detection and smoothing, this does not effect temporal aliasing of any kind what so ever.


The blurring in TXAA is not because of some pass that just decides to blur it. TXAA uses a different resolve filter than the standard box filter used by GPU hardware. A custom resolve is also as it implies. Custom, meaning that the resolve filter has been tweaked according to the intentions of the technique. To reduce as much temporal aliasing as possible.

You can see an article on such a thing here
http://mynameismjp.**************/2012/10/28/msaa-resolve-filters/

There is even a demo you can download and experiment and see how different filters impact things.

And as you will see, some of them average out the image, making it softer.

Need proper post with comparisons (Lossless PNGs please) and some formatting for ease of visibility for readers please

 

I might've just solved the entire GeDoSaTo-Driver Forced Anything problem..

If my testing proves accurate



And if you prefer something sharper...

 

Please tell us how to do it MrBonk

 

Oh I most certainly will!

I need to do more comprehensive testing, and talk to durante about a scaling thing to keep in mind in the future.


Once I am done, I will make a fairly large post trying to explain everything and the options you all have as users.

 

This mean while FXAA is edge detection and smoothing TXAA is in the post processing part simply smoothing but instead of using an box kernel its using a custom kernel?

 

Great work!

 

Playing on a laptop with a GTX 780M, o/c to 950MHz core and 6000MHz memory
GoDoSaTo downsampling from 1440p to 1080p with:
- 4xMSAA and Alpha Coverage
- Shadow Scale 4
- Present Interval=0
Borderless Fullscreen Mode
nVidia Inspector:
- 16x Aniso
- Force VSYNC (though probably has no effect in borderless fullscreen?)
D3DOverrider to force Triple Buffering (again, maybe just placebo effect in borderless fullscreen)
Runs at a SOLID 60FPS with occasional dip to 55 on loads/transitions
The game is beautiful

Ryse has some great post antialiasing, and this is coming from someone very fussy when it comes to post aa. I'd say it looks better @ native @ 2560x1440 with post aa, than 5k (that's right, 5k) without post AA.

The game has the following options:
Upscaling, Supersampling, Downsampling, Post AA.

I would actually call this post AA near-txaa level. FAR better than dead rising 3 and alien isolation attempts, and with only 10% the performance hit of TXAA and 2% of downsampling/SSAA.

NOT BAD.

By the way are those final fantasy screenshots kind of dark, I find the background hard to make out. Maybe i just have dim vision.

 

RE: Dark FFXIII screens

Those particular scenes are dark due to the locations, but the lighting in the game is not modified. Scenes that should be bright certainly are

I'm still in a fairly dark area, but maybe these look better?

Wow, really? That sounds great, because SMAA T2x in every game i've seen it in (Even the original Crysis 2 example when they created the technique) looked utterly mediocre

 

I agree, Ryse son of Rome shows the best quality post effect AA ever? great quality
now we only need a good sli profile

Edit: now if Crytek would like to share his nice post AA with the rest of developers...

 

Well maybe you might disagree then, because I liked it's useage in crysis 2. This is clearly better, but it's cut from the same cloth. It does wonders for edge aa and makes round/soft things almost shimmer free. Creates a soft look without making the textures very blurry or some glaring compromise.

Oh, and it scales up with resolution/down-sampling wonderfully. Kind of makes the whole DSR thing something fun to experiment with at 7fps.

Yeah, if alien isolation had that post aa, nobody would even be considering expensive downsampling. Same goes for dead rising 3. This is the best smaa tx2 i've ever seen, and it should be the standard for post aa. What puzzles me about it is that it also takes wonderful care of the edges, so 98% less temporal shimmer and 90% less edge aa.

Things like dead rising 3 with it's tx2 implementation added additional shimmer, this on the other hand removes pretty much everything. I mean, sure, txaa removes even more, but this is a damn fine attempt.

Kind of brown and dark for me. Lacking vibrancy and has this yellowy green blackness. But it's better when i fullscreen it, although still kind of dark/brown/poo looking.


--------------
Separate note
--------------

Ryse has a HBAO+ flag. I tested it and set it to "quality" via nvidia inspector, and it improves the visuals even more. However I really have to wonder if the game was already using some kind of SSAO/HDAO.

 

Oh, no the stuff used in Crysis 2 retail was pretty ok!

I'm talking about this
http://www.iryoku.com/smaa/downloads/SMAA-Enhanced-Subpixel-Morphological-Antialiasing.mp4


Dead Rising 3's SMAA T2x is pretty bad. It somehow manages to completely miss stuff that even FXAA and SMAA 1x Gets



As far as Ryse is concerned, the game has more than just the post-AA (Which is an updated SMAA T1x from the XBO version), it also has AA at the material and shading level to help reduce problems.

From what I recall, if you turn the postAA off, and then change the graphic setting from the max to the lowest, it will deactivate some of that


ALSO: Ryse *does* have SSDO and some other forms of AO.

If you look for slideshows and presentations from it, it has it in there

 

I think nvidia's hbao+ flag is a lot higher quality (no surprise there) so i will await a command or some way to edit individual settings so that i can disable the ingame version. Otherwise i'm taxing the framerate for no reason by combining them.

Turning post aa in ryse off, adds a world of shimmer and aliasing, it looks like a different game. However no other setting makes this better/worse other than post aa. You would think shaders, but not the case here.

 

They did shared about many AA solution with the PPT, each time they released a new crytek game, they will talk about it, and here is the Crysis 3.

And here is the Ryse, with any other game that share the result about AA solutions.
