I remember this from ATI. They called it "Dedicated AA" and nvidia has something similar at the 9xxx series. It died with the 3xxx series on ATI side at least.

I mean, if you use nvidia inspector you can find the settings, as they are still there.
But it won't turn off SLI anymore as far as I can see from the information section (hadn't test it, not at home).
Its there under the SLI section in antialiasing SLI AA, and you can make it enable, but I wouldn't count on it working.

What do you mean 'I can google that as well'?

I was just showing you I know what I was talking about ... it's been around forever man wink.gif

I posted a screenie above ... looks like it's still very much a current feature.

You just have to have SLI actually enabled for the options to show up ... forgot I was doing some dedicated physX tests on my 2nd card earlier ...

There is an article at Tom's, they are looking at driver-enforced AA and that half the time it didn't work so well.



Anyways, wouldn't the performance scale the same with or without AA?..

This is something different.

On tom they were trying to force a single card to do certain versions of AA (like MSAA, TRAA and others).

This is a way to make one card do all the AA calculations and the other to do the rendering in 2-cards situation so you can "unlock" very high AA options.

Yeah, I've been telling people for years that NVCP-forced AA very often doesn't work. The Tom's graph bears out that point ... although it's nothing to rejoice over

But, SLI AA does appear to 'work', at least in the traditional sense. And when you select SLI AA it pops up with a message telling you that you are going to be disabling SLI Performance Mode by using it. That piece, however, doesn't quite work in the way I was hoping for.

I fired up Singularity, which is a game I know for sure that forced AA works on. First I forced regular 2xAA and 2xTRSSAA (SLI Enabled). I saw usage on both cards in the range of 30-35% on each card, and vram usage around 540MB.

Then I went and enabled SLI 32xQAA and SLI 2xTRSSAA and went to the same scene. Et voila ... 90-99% usage on both cards, and 1050MB of vram usage. There was definitely less jaggies, too. SLI AA does, indeed, work on the expected games.

However, not quite in the way I'd hoped, which was that I'd actually see different usage levels on each card so I could see how much work the 2nd card was handling by doing the AA. Instead I get equal usage on both. And given this fact, I can't really think of a way offhand to positively confirm that each card is being used for these separate purposes ... although I suppose I compare GPU usage on one card with sli forced off and 32xAA vs. gpu usage on both with SLI 32xQAA and if they're reasonably close it would imply that the SLI really is disabled w/SLI AA ... you just can't specifically 'see' what the second card is doing, usage-wise ... you just see a 'mirrored' value from the first card. If that makes ANY sense

Lastly, I also tried it on Dead Space 2, which does not appear to support forced regular AA ... also doesn't appear to support forced SLI AA. I'm sure I can use a similar method as the one I described above to see whether 'SLI Disabling' action takes place when SLI AA is forced on in a game where forced AA doesn't work ... but I'm getting tired. I'll mess w/it tomorrow.

Are the FPS you get similar to the ones you get from normal SLI?

If you run SLIAA and for example 4xAA vs normal SLI and 4XAA, you get the same results?

If you do, it means that it would just let you unlock the AA, but not really do SLIAA like in the traditional sense, and its not "really" working.

That's sorta what I'm saying I'm going to test. There is no SLI 4xAA though, I'm going to have to test regular 32xAA (the highest) vs SLI 32xQAA (the lowest SLI AA).

I.E. compare perf between these two cases:

1) Two cards in SLI running 32xAA on the set.
2) Two cards not in SLI, one running everything but AA, and the 2nd card dedicated to the 32xQAA.

If the only actual difference in functionality was a slightly higher AA level (i.e. what was really happening is that both cards are working in SLI still, it's really just a higher level AA running as normal on the SLI set even though it says SLI AA) the difference in perf should be small. But if the perf is way lower with the SLI AA I'll conclude it really is taking one card out of SLI and dedicating it to AA as advertised.

Trouble is, it's still a bit of a 'guess' as to whether or not the 2nd card is really being taken out of SLI and used for AA no matter how I fashion the test, because you don't know for sure what the difference *should* be between these two scenarios.

If it's anything but a large difference in favor of 1) above, I'll still not know what to conclude is my point.

My intuition, though, is telling me this SLI AA is in fact working as advertised. I don't think the message saying 'you're taking your two cards out of SLI if you use this mode' would've been there if it wasn't true.

Sure would've been cool if you could see different GPU usage on the card that's dedicated to running the AA ... it would've be interesting to see how much usage AA accounts for in this way.

Thank you for all for the feedback and testing.

The majority of the games I play will work with Forced AA, but that doesn't mean that the games I will be playing in the future will.

I'm still on the fence though about SLI, and will probably just buy a single powerful GPU. I was hoping that if SLI doesn't work, I can rely on falling back on SLI AA, but even if that only works part of the time then I don't see the point in it.

Unless I misread what you posted.

Honestly there are SOOO few games that come out that don't have SLI profiles ... and even when that does happen, it's usually only a short time before there's a new driver or SLI Enhancement pack that does. Personally I almost never buy brand new games cause they cost too much and I like to wait for reviews anyway ... so by the time I get 'em, the profile is already in the driver.

Also there's tricks that can be deployed like renaming the new game's .exe to the name of some older game's .exe that does have a profile, or adding an association with the new game to an older game's sli profile using nVInspector (both these tricks has the same net result).

Special Secret Instructions to 'Force SLI' Revealed HERE!

Of course you can go with the amazing, uber-secret 'FnkDctr Forced SLI Method' that we all learned about recently ... nobody had ever tried or really even thought of his method until he came along and bequeathed his unparalleled SLI wisdom upon us

In case you don't know, 'Forced SLI' is where you add a new, blank game profile in NVCP and point it at the .exe of your new game (you'll probably find these .exe's in 'Program Files' folder, in case you aren't aware) and 'force' the game to use this slick trick they call 'Alternate Frame Rendering' instead of regular 'Native SLI'.

What, you don't know about 'Native SLI'? That's where the game code directs one card to do like 'details' and the other card to 'textures' ... I suppose you didn't know that's how SLI normally works?

Seriously ... all you gotta do is google 'Forced SLI' and you'll get like 7.2 million results ... that's how you know it's a real thing!

Err ... wait ... actually there's no such thing as 'Native SLI', all SLI is AFR, and this method only actually works like .0025% of the time because you aren't actually creating a proper SLI profile ... but it HAS worked at some point in the history of gaming, and that's what important

I couldn't find any pictures of 32xAA really, do you got any? I want to see how it looks compared to 8xAA
