Yep, it is better.

If you use GeDoSaTo, you can choose which scaling algorithm you want to use, so you can downsample with Bicubic downsampling, or Lanczos downsampling and get visuals that are identical to what most people get resizing afterwards in Photoshop.

Also, GeDoSaTo does multi-step downsampling, meaning resolutions above 2x your screen res get downsampled more than once.

Ex:
5120x2800 -> 3840x2160 -> 1920x1080 w/ Bicubic filtering​

as opposed to

5120x2880 -> 1920x1080 w/ Bilinear​

Which provides better results. Along with all the other benefits it offers, if it works for a game, it's basically a straight upgrade!

Regular driver downsampling is limited to a useful ratio of 2x2 generally.
And it only uses a bilinear filter.

However, GeDoSaTo doesn't really have a resolution limit, and better filters to choose from.

But, downsampling a game with noAA at the downsampling resolution still is going to look very aliased. Regardless of Driver based or GeDoSaTo. Even Nvidia's built in OGSSAA modes (1x2,2x2,3x3,4x4,etc) suffer the same issues in a lot of games.

If you downsample, you generally need to combine other AA methods in conjunction to get a worthwhile result (IE: MSAA,FXAA/SMAA,other post processing AA). Unless you are playing your game at insane ratios that are unplayable.

Very interesting. I might have to start using it then.

Thanks for the answers.

Gotta take a moment to complain about this game.

GeDoSaTo works, but visually it's not nearly as interesting as an ENB mod (sorry, Durante!), and the AO is kind of... not great. ENB is great when it works, but the AO is buggy as hell with an outsized performance hit. HBAO+ is also great when it works, but it's just as buggy as the ENB AO, with NONE of the bits working 100% (one flickers on and off, the other shows up through fog and UI, the other will flicker AND send the framerate to a crawl in certain scenarios).

So it's basically a game of making compromises, at least for the visuals. At the moment I've taken it upon myself to just use the ENB with HBAO+ and accept the fact that things are going to be a little wonky at times. At least the game looks nice!

Compromise indeed. Personally I think I would just end up disabling AO all together completely.

I'd also like to show some practical examples (Though stills can only do so much)that downsampling by itself is innefective.

NoAA http://abload.de/img/noaa3jpqy.jpg
2x2 OGSSAA via a compatibility bit for inspector (nvidia cards) http://abload.de/img/2x2ogssaatru1m.jpg
2x2 OGSSAA via driver downsampling http://abload.de/img/3840x2160downsampledtv4uvd.jpg (If you also notice, driver downsampling has an additional benefit in this case. Being the AO is higher quality vs native and driver 2x2. Effect is fractional. Thus increases when main backbuffer does as well)
8xSGSSAA via a compatibility bit for inspector (This bit used for example has less averaging ;blur; than the other bit that can be used. And thus still has some aliasing left because of this. But is useful for the point) http://abload.de/img/8xsgssaaaafixon18kh7.jpg
(Other bit 8xSGSSAA for example http://abload.de/img/8xsgssaaaafixoffsgrly.jpg)

The author of the pictures in this case didn't try downsampling + any other kind of AA. So I can't show that without doing some specific testing myself. (Which I don't have time for until Friday).
And there isn't one for GeDoSaTo for example(But the results would still largely be the same)

But it does show the point and using some other form of AA in conjunction with downsampling would provide the best results.

I've seen some shots here where people are downsampling from crazy resolutions, and yet there is still tons of easily visible aliasing (At least to my eyes. Which are used to looking at this stuff like crazy).


The awesome part now though with DSR, is that you can use say 4xSGSSAA or 8xSGSSAA and do some slight downsampling (IE 1.2x1.2 or 1.5x1.5) and use Nvidia's new filter to increase the sharpness to counteract some of the blurring if that's an issue for you. (if a particular flag for a game has such an issue to your eyes) Thus you'd essentially get the best of both.

Holy fuck! How does this run?! Could you post more pics please? :)

Well, at 7MP with AO, DOF, shadows and some SweetFX post-processing shaders all at their respective extreme quality settings, this honestly runs like crap on my GTX 680 (2GB), i5-2500k. I'd say around 8fps in exteriors. That said, the amount of grass and HD textures in my game are also severely limiting performance. With the ENB/SFX combo off, I barely get 30 fps at this resolution because of it. I'm also throwing all kinds of ENB and SFX-derived AA at it.

But if I ramp down the quality settings a bit, the general look is mostly similar and perfectly playable. At 1080p this runs smooth as butter.

If you want to see more of my Fallout shots, you can delve into my past 3 years of tweaking ENB's for it over on my Flickr album for FO3. It has close to 500 shots. My Fallout NV album has about a tenth of that amount. You'll find the most recent shots at the bottom.

Thanks a lot for the explanation. I'll give DSR a try. It's been a while since I last updated my drivers.

EDIT: nvm, 900 only, but I got GeDoSaTo running. Now, to test a million times between bicubic and lanczos. Alt F4 is my friend, I guess.

Aha, I knew it looked familiar. This is that game that's using laser scanned real-world assets (alongside regular ol' game assets). Nice to see it was worth the effort.

Yeah, that's probably the sane course of action. But I'm just so damn used to the effect that running any game without it feels like surrendering.

In other news, I fixed my blurriness problem! As a side-effect, yeah, the CA effect is much more noticeable now, as is the film grain, but I still think it looks quite nifty.

I must be the only one not overly impressed by Ethan Carter. Looks good but seems to have a blurry look to it all. edit: well not blurry, just painting-like, too soft.

It reminds me a bit of the Metro series, the screens don't do it justice. It looks way better in motion, with the leaves and grass and textures all moving around.

Honestly I think screenshots of Ethan Carter can only hurt it. Looks mind-boggling in motion. And the 980 is maintaining 40-50 FPS at 5120x2880 =)

I couldn't resist this one though:
