Gaming Performance - SLI and Resolution Scaling

With the initial benchmarks out of the way, let's take a closer look at how performance improves with the addition of a second GeForce 8800M GTX. We'll have results from the XPS M1730 in single GPU and SLI modes along with resolution scaling results from the AVADirect M570RU.




































(Ed: Again, sorry for the plethora of pictures... would you prefer three pages of charts, fewer benchmarks, or some other solution?  Or is this good?)

So what can SLI do for you? These days, quite a bit. At lower resolutions, the benefits aren't as great, particularly in older titles. We also have several games that are clearly running into CPU limitations: Battlefield 2, Crysis at medium detail, Far Cry, certain areas in the Half-Life 2 games, Oblivion, Supreme Commander, Unreal Tournament 3, and World in Conflict all show relatively flat lines for the SLI system. On the other hand, Crysis at high detail, Bioshock, Call of Duty 4, Company of Heroes, FEAR, Enemy Territory: Quake Wars, and even Quake 4 show substantial improvements regardless of resolution.

Let's look at the data organized in a different fashion to make things a bit more clear.

    So let me see if I understand this correctly, Nvidia will not be offering mobile drivers to the public but will make them available to the vendor who can validate them and then offer them to their customers on their web site? ie through Dell?

    See above. There will still be official driver updates from the vendors after validation, presumably - or at least, they'll come as often as they have in the past. :)

    Jared,
    How about a link to the beta drivers? I checked the nvidia web site and can't find the 174.20 drivers you used.
  • JarredWalton - Saturday, March 15, 2008 - link

    The 174.20 drivers were directly from NVIDIA but they are still undergoing testing and validation. The plan was to hopefully have those available (well, an updated version that addresses a few things probably) within the next month. Note that the LaptopVideo2Go 174.xx drivers are not the same, as those are based off the desktop parts and lack mobile optimizations as far as I can see.

    When they finally are on Nvidia's website, will they only work for 8800M GTX's or will they also work for 8800M GTS's? I have a P6831FX Gateway and would love some newer drivers. :)

    My understanding is that the next "Mobile Driver Update" from NVIDIA will cover all GeForce M chips on Vista 32-bit/64-bit for participating vendors. So that means the Gateway FX, Toshiba X205, Dell XPS, and various Clevo notebooks should all work with the beta driver. Probably some others as well. I *hope* that they get GeForce Go support on Vista as well with the next driver, and likewise I would appreciate seeing new XP drivers for both Go and M series cards.

    So these drivers will not be offered by nvidia to the general public but will be made available to dell to offer after they validate them?
  • JarredWalton - Monday, March 17, 2008 - link

    No, the "Mobile Gaming Drivers" or whatever you want to call it are going to be available from NVIDIA. The last release came just before 8800M launched, so it only supports up through the 8700M. They also didn't cover all GPUs on all OSes - so 8400-8700M got Vista drivers and GeForce Go 7xxx got XP drivers.

    The laptop vendors do have to agree to participate - so Dell pretty much tells NVIDIA it's okay if they release a driver that will work with the XPS laptops, as an example. Note that this is not just a vendor decision; it's a model decision as well. So while Dell is okay with "beta" drivers direct from NVIDIA for their XPS (gaming) laptops, they don't want beta drivers for Inspiron or Latitude laptops.

    Normally, notebook vendors do not allow manufacturers to release "reference" updated drivers that support the mobile chipsets, which is why we see stuff like LaptopVideo2Go.com. Well, this is a step back from that stance, but only for laptops where updated video drivers are a major concern. Thus, the vendors still have to give NVIDIA permission to release the drivers to the public. Make sense?

    Great article. Kind of curious about the casing in the pictures. The latest version from Clevo for systems with X9000 processors has a slightly different casing, labled "Extreme Edition", with an additional molded section on the bottom to provide for better ventilation around the CPU. Wonder if AVA is shipping old case versions?
  • JarredWalton - Saturday, March 15, 2008 - link

    Thanks for the comments. I've had this system for about a month, and it's pre-release. It could be that the final shipping models will cool the CPU better, have a working overclock for X9000, and not be as loud at idle. I can only hope so.
