ATI Cheating Benchmarks

Ok well this is where it gets interesting. Saw this on some foreign pages the other day that I couldnt understand but RageUnderground (Thanks HardOCP) has the scoop on what ATI was up to with their Quake3 specific drivers. Seems ok to me to make your cards work faster on apps that you know are popular, until you see this:

- yes, we did do optimizations specificly for Quake 3. - yes, we did it because it is being used as a benchmark in reviews of our cards. - yes, we sacrificed imagequality to gain better framerates.
That is just plain underhanded. It's one thing to make sure your drivers work well with particular apps, but its a whole different thing to actually make the game uglier in the name of benchmark numbers. Especially when the only way for people to disable this option is hacking drivers or renaming their EXE files. Score one for ATI!

  • The people who don't think ATI is being underhanded don't understand what they've done.

    Image quality differences between Geforce and Radeon, if they exist at all, are slight, to say the least.

    ATI has done two things to make their card run faster:
    -1. They've changed certain 32 bit textures to 16 bits
    -2. They've blurred Q3 textures to a degree equivalent to [i]r_picmip 1[/i] in the Q3 engine

    Essentially, this is Q3's normal quality setting, al beit at a higher resolution.

    As a result, if you run benchmarks with the unmodified q3 executable, you get these results:
    ATI: q3 1024*768 [i]normal qualit/i]
    Nvida: q3 1024*768 [i]high qualit/i]
    [i]Even though when the ATI machine reports that it's in high qualit/i]

    This is sure underhanded, if not blatant fraud






















  • The sooner ATI releases a patch that allows people to turn this "feature" off, the better off they'll be.

    It seems to compress the textures at the outside of vision, without compressing the ones in the middle as much. Sounds like a good idea; the stuff at the outside is usually going to be in my peripheral vision anyway...but ONLY if the user can actually control it.

    If I could turn the thing off, or -- better yet -- TELL it what qualities to make each section of the screen be, then this would be a good bit of driver code, yet another way to tweak the game's settings to my preference.

    But you can't turn it off, or change it in any way...and ATI didn't even admit to using it.
    I can't imagine them thinking of it as a FEATURE; if it was, they'd have a snazzy name for it. So why put it in, if not to inflate benchmarks?

    But shit, it's not like corporations never do anything unethical. This is just unethical and STUPID -- but it'll take their coders an hour to patch it to do what I've suggested, if they are allowed to.
