Wolfenstein: Enemy Territory Performance

We included Wolfenstein: ET in our test suite for SLI for one reason and one reason alone, to look at an older game to show SLI’s impact on a title that ran very well even on a 6600GT. 

Wolfenstein: Enemy Territory

You can see by the resolution scaling graph that we are completely CPU bound at all resolutions here, much like what we saw from UT2004.  Only the 6600GT actually benefits from SLI, bringing it up to 6800GT speeds thanks to a 31%  performance improvement.

With the 6800GT and Ultra, even at 1600 x 1200 with AA/AF enabled the performance gains from SLI are nothing major.  The 6600GT continues to provide impressive performance gains, bringing it up to the level of a 6800GT thanks to SLI. 

Wolfenstein: Enemy Territory

The important thing to take away from these numbers is that on today’s high end cards, SLI is very much a technology that is suited for the latest games as well as tomorrow’s titles.  But for midrange cards SLI can definitely enable higher resolution and/or AA gaming.

    #61 good point, I also wonder how well it runs at super high resolutions...

    We've seen profiles for many games in nVidia drivers since the 5x.xx series, I expect the SLI mode is just something they've added to it for when the card is running in an SLI mode. If in doubt, I'd have thought SLI AFR will be fine for most games that don't have a profile defined (assuming you can choose SLI mode), or SFR for those games that use motion-blurring (usually certain types of racing games).

    where in the review talk about the profiles?
    Is there a list of the games that can enable SLI?

    Where is the 2048x1536 tests? It is clear that 1600x1200 is no match for the SLI setup in most games. Why not do testing at higher resolution.

    If 2048x1536 ran smoothly, Then the demand for better monitors would be stronger - giving manufacturers reason to make better monitors for us =).

    #55- If SLI is only able to be used on games nVidia have profiled like you say, and that the user cannot themselves force it to run in SLI AFR or SFR mode, then that's a serious problem for people who play non-mainstream games who might be considering SLI.

    After reading this article, I now believe more than ever that the only people who should be seriously considering SLI are those who are willing to buy two 6800GT or 6800 Ultra cards in one go, in order to have a top of the range system. The upgrade option doesn't make sense.

    Anand didn't compare the costs of an SLI upgrade against a non-SLI upgrade; instead he compared buying a second 6600GT later on when they're cheaper, to buying a high-end card initially and *not* doing any upgrade. Of course it's going to be more expensive if you buy a high-end card from the outset.

    The true upgrade alternative is that instead of buying a second (now cheaper) 6600GT to achieve roughly 6800GT performance, you would sell your 6600GT while it can still fetch a good price and put the money towards a (now also cheaper) 6800GT or maybe a mid-range next-generation card that has the required performance. When you look at how much prices fall on high-end cards when something even a little faster comes out, pushing them nearer to mid-range cards; it should be obvious that replacing the card with a faster one is a more cost-effective option for anyone considering an upgrade at a later date, than buying a second identical card on top of the one you already have.

    Yes there's the hassle of selling your first card, but not only do you have total flexibility over what you upgrade to (with SLI you have none); you also don't need an SLI mobo, you won't have two graphics-cards generating excess noise, and you'll have a lot more PCI/PCI-e slots left free for other cards.

    IMHO, SLI is for people like me and also for people that need to have the latest and greatest. People like me don't upgrade every 3 months, 6 months, or even a year. I upgrade every 2.5 to 3 years. It would be nice to be able to run 2006 or 2007 games on 2004 technology. Who knows, this might extend my upgrades to 4 years. ;-)

    #56 I would imagine that nVidia is aware of this and who knows, they may implement a utility within their driver that automatically flashes the BIOS of the "older" card, if one is detected. Either that, or they could write something into the driver to search for another GPU and once it's found, ask you if you would like to flash its BIOS upon restart. And voila!

    The fact of the matter is that it's way too early to speculate as to whether or not SLI is a viable and cost-effective solution. Something tells me that it will be because it's not like the "next big thing" ie: cards that are twice as fast, are right around the corner. If they were, then I'd say 'no'. It isn't worth it for reasons stated by #42.

    I think the issue of the card to MUST have the same bios is ENORMOUS. So the buy one now and buy the other LATER will "not" be possible. I doubt that a year old card has the same BIOS of brand new one.

    Too much “issues”…

    I want one of this SLI boards but the article said that you can force the driver to enable SLI on games without profiles on Nvidia drivers but this is not real.

    If no SLI profile exists for a game, there is no SLI rendering. It is not possible to force SLI mode or generate your own profile. According to NVIDIA however the driver already contains over 50 profiles for games running with SLI. For newer titles this therefore means that SLI system owners have to wait for a new driver. But even then there is no guarantee that SLI will be possible with a particular game. So this is not very good news.
