SLI Supported Games

[OPaul]

In nForce4 SLI Roundup: Painful and Rewarding it states the following;

This may get a little more complicated if nVidia turns on SLI by default when the driver sees an unknown, but for now, you need a supported game for SLI to make sense.

But I've been told on Neowin that all you need is a NVidia profile file for the game to work under SLI. So did the people who wrote up this review not use the profiles with games like UT? And if I did use the profile can I except to see a drastic increase in performance with 2 cards over one?

Yes and No. SLI supported games (not many out) do increase graphic performance but I wouldn't say drastically. I'll find that link....It's a video of a guy testing DOOM 3 on full settings, first with one 6800 ultra, and then with 2 in SLI mode. The first card provided 43FPS while playing the game, while the SLI gave a constant 75FPS.

But when you say "SLI Supported Games" does that mean just a profile from NVidia or does there have to be code written within the game itself to take advantage of SLI?

 

[KeepItRed]

Code written inside of the game.

The Nvidia profile could be ON and to your settings, but when you run a game it won't apply because the GAME doesn't support SLI.

Well, let's be clear here. I'm not aware of ANY game that was coded with SLi in mind. That, however, does not preclude SLi actually working for the game. nVidia has basically stated, as was already said, that just about any title should see a benefit from SLi, if the proper profile is created, with the proper render mode.

Don't quote if you have nothing to say Mr.Fanboy.

Exactly. I know of no game that was created with specific code to take advantage of SLI. THe game code has nothing to do with SLI, in fact, because SLI is all done in the drivers. As long as you created the correct profile (or Nvidia did) with the correct rendering method (AFR or SFR) than it will work fine.

IIRC older games are not capable of SFR and must do AFR to work correctly (might have gotten that backwards).

Edit: There is no reason you should have said anything to him. He simply agreed with an above comment. So instead of trolling (like in that post) why dont you post what you have to say and logoff.

I believe he just forgot to put QFT.

You really know nothing at all about SLI, do you? Why do you post totally inaccurate info about SLI?

Are you dense, or is that your job? Let's take a look at your latest pack of lies and mistakes:

Like I said in the other thread you spouted this total BS:
1. ~75 profiles is not "not many" games. More importantly, you don't need a profile to use SLI or get benefit. You can set it to default to AFR1, AFR2, or SFR on non-profiled games right in the driver control panel. Yep, you can force SLI on ANY game?

2. 43fps to 75fps isn't a "drastic" improvement? :roll: It's a 74% performance increase? I've got news for you, biased and inacurate one, whatever vaporware Crossfire turns out to be, it won't be offering 74% gains often. That is a HUGE gain, about as good as you can do.

Total BS. There are no games with code inside them for SLI. :roll:

Your posts are worse than worthless: they're misleading.

"I've got news for you, biased and inacurate one" sounds more like you, your all Mr.Nvidia. You don't know a single thing about ATi or other brands do you? I pity you. Nvidia isn't the only company out there, at your level you only know ATi's colors are red and white.

Just look at your posts. Your all OMG 7800 BENCHES!!11one1eleven

"There are no games with code inside them for SLI" Link please.

LOL- how old are you? 12?

 

[KeepItRed]

Actually I'm 16 you seem to be the biased one whining about 12 year olds...

Rollo, I don't wanna start **** If I'm wrong, correct me. Don't get all rambo on me, we were all newbs before and I'm being educated.

Back on topic, boys.

This has already been gone over, and the facts of the matter have already been stated. If you can't contribute, don't post.

I'm surprised [and slightly disappointed] that no one pointed this out before.

A list of all SLI-optimized games.

 

[Ronin]

Optimized? No. Have profiles for? Yes. I realize they use the word 'optimized', but I wouldn't necessarily consider that accurate.

Fair enough.

However, if you're a newb, why do you post things that are wrong? Shouldn't you mainly be reading and asking questions, rather than posting things like "SLI only works on a few games" or "games have to be coded to SLI".

If you post stuff like that, someone else who doesn't know may think you do and believe you?

I like you too Ackmed.

Ok Rollo, now that your talking in a decent tone. I post what I hear. I like to google info and learn as much as I can. Incase you haven't noticed I TRY to help people, and if I'm not sure I put (I think) and I prefer to ask LOTS of questions.

So in the nForce4 SLI Roundup: Painful and Rewarding review Wolfenstein and UT2004 saw no gain at all and Quake 3 only a slight gain. If all games can take advantage of SLI and two video cards by making a profile or using one supplied by NVidia why did these 3 games not seem effected? Did the person reviewing not create a profile or is there something about the games engine that prevents SLI?

What is AFR and SFR?

 

[Ronin]

AFR stands for "alternate frame rendering," meaning the two GPUs running in an SLI configuration take turns rendering the frames. Nvidia's AFR algorithm scales geometry processing, since the two graphics cards work in parallel, each processing the geometry for alternate frames. AFR also scales pixel shading and fill rate.

SFR stands for "split frame rendering," meaning each frame is split into two portions, with each GPU rendering one of the portions. Dynamic load balancing is used to divide up the workload evenly between the two GPUs. This load balancing happens on the fly and changes from frame to frame.

Both Quake 3 Arena and Wolfenstein are based on a 5-year old game engine. It makes sense that SLI would have less of an effect. Newer games are more demanding on the graphics card(s), so SLI tends to have better gains in newer games and higher resolutions.
