HydraLogix Vs. SLI And CrossFire: MSI's P55A Fuzion Tested

Features

LucidLogix forges ahead with its promise of multi-GPU compatibility across multiple graphics architectures and platforms. Today we see how its latest drivers stand up to the performance standards of CrossFire and SLI on a much more cost-sensitive board.

Benchmark Results: DiRT 2

HydraLogix supports DiRT 2 in theory, showing up on Lucid’s game list, as well as displaying its logo within the game itself. Whatever the level of support might be, though, we don’t realize a performance benefit from enabling this technology.

We once again call into question MSI's decision to omit an SLI bridge with a board that supports all three graphics-combining technologies.

The lack of a CrossFire bridge in the motherboard pack is often mitigated by its presence in graphics card packs, but MSI unfortunately doesn’t include the bridge with the R5850 Twin Frozr II cards we used for today’s CrossFire configuration.

    Still seems to buggy to me but at least they're still working on it right?

    Looks good on the 1st 2 games and synthetics.
    I hope Lucid gets all the issues worked out.

    So basically it's just a universal CF/SLI connecter built into the motherboard? Seems odd that it's taken this long to be developed, but great nonetheless :)

    Looks like it has some promise, if they can further work the kinks out. Something to keep an eye on in the future.

    The 6870 scales better in cfx than that 5850. Why not test that?

    I can see it as a standard in the future. I think I will buy a board with Hydralogix on my next build.

    It would have been nice to see how well this works with two differing AMD/ATI cards and two Nvidia cards. For instance someone has a GTX260 and wants to add a GTX460, or someone with a AMD5850 who wants to pick up a new 6870 (damn numbering change) to go with it.

    Also comparing performance pairing two cards from the same generation (say GTX 460 + GTX 470) vs differing generations. (GTX 260 + GTX460)

    Lastly what affect would pairing a two cards with varying amounts of memory have? (two regular versions of a card vs 1 reg + 1 dbl memory vs 2 dbl memory) Since it isn't clear from what I've read if both cards would be limited to lowest memory level or not.

    Interesting tech for sure

    this should become a standard, allowing us to enjoy features from both manufacturers. I would also be prepared to pay few extra bucks for this as well.

    Overall,Lucid is a great idea of mixing different cards but it still needs quite a lot of work with drivers.

    Ah, thank you. It was posted before I was frequently following the site, I'll give it a look.
