High End GPU Performance w/ HDR Enabled


The white lines within the bars indicate minimum frame rate

At the very high end, in our most strenuous benchmark, $1200 of graphics cards will buy you less than 50 fps on average. It doesn't actually matter which vendor you go with, both ATI and NVIDIA offer similar performance at the very high end with one very important exception: ATI seems to offer much higher minimum frame rates than NVIDIA at the very high end in this test. We tried adjusting the render ahead setting but couldn't improve the situation any for NVIDIA, so while both ATI and NVIDIA's best performers offer similar average frame rates, the ATI Radeon X1900 XT CrossFire setup is better overall thanks to higher minimum frame rates.

Looking at single card performance, once again ATI takes the crown as the Radeon X1900 XTX has higher average and minimum frame rates than the GeForce 7900 GTX.

What really puts things into perspective though is the performance of the GeForce 7800 GTX, a GPU that was at one point a $500 king of the hill now falls in the lower half of the graph. Unable to average more than 20 fps in this test, the settings we're running at here are too much for the GPU. Given that we haven't turned up every feature and are running at a relatively mainstream 1280 x 1024 resolution, this chart alone gives you good indication of exactly how stressful Oblivion actually is.

GeForce 6 owners should no longer consider their GPUs as high end, because Oblivion certainly doesn't. Even a pair of GeForce 6800 GSes can't break 15 fps in this test and with a minimum frame rate of 10 fps, they make the game far from playable at these settings. No, believe it or not, but the GeForce 6800 GS performs like a mid-range card at best under Oblivion.

At our high quality 1280 x 1024 setting, virtually all of the cards offer nearly identical performance when walking around inside a town, even down to the minimum frame rates. The problem with these numbers is that you really can't determine what settings you'll be running Oblivion at based on your in-town or in-dungeon performance, because the moment you step outside you'll find yourself watching a slide show. It's also worth noting that although a lot of these cards have average frame rates in the 50s, their minimums all drop to right around 30 fps. If we crank up any of the detail settings we'll be looking at even worse minimum frame rates, which are just as important.

We see no benefit to SLI or CrossFire here, due to whatever limitation we're running into at these settings. What we will investigate in future articles is exactly what is causing this limitation; we would assume we're CPU limitated even though we're already running an Athlon 64 FX-60. That doesn't bode well for other processors, as there simply isn't much more we can throw at the game.

It isn't until we get below the GeForce 7800 GTX that performance begins to drop off for our contenders here and once you get slower than the X1800 GTO then the minimum frame rates begin to dip below 30fps.

Like our Town test, our Dungeon benchmark shows the cream of the crop performing very similarly with performance only really dropping off below the 7800 GTX. Although our Dungeon test also runs into some sort of a performance limiter, it appears to be a different one than what we saw outside walking around the town because our average limited frame rate is now up around 80 fps instead of 50 fps.

What the combination of these three tests show is the full gamut of performance of these GPUs under Oblivion, from the worst conditions to the best conditions. And while everyone is fairly competitive indoors or walking around a town, once you journey beyond the town walls you can really start to appreciate a faster video card.

    If as you say the error in your measurements is about 5% which for a 30fps score is about 1.5 fps then it is not warranted to post measurements like 31.4 fps. The .4 in there means absolutely nothing. It is clearly not a significant digit. You should either perform multiple measurements to reduce the error or post the less accurate results which you _actually measured_. Reply

    I like the new graphs you've been using lately, what software is it? thanks :) Reply

    Check page 7 of this article, titled "Mid Range GPU Performance w/ Bloom Enabled"
    How come the both the vanilla 6800 and the 6600GT outperform the 6800GS? It hing the resutls for these cards were somehow entered wrongly while making the performance graphics...

    Some people need to look at the overall picture on video cards instead of just saying that ATI is the best because it runs the best on Oblivion. If you look at other reviews with games like HL2 and Doom3 you will start to get a different picture of what card is better for you. Don't take this one review buy a new video card and think it is a cure for all games. Especially for whoever said that the 7900GT sucked. That is a great card and performs well in most game. If you don't want it just mail it to me.

    Personally I think I will wait until the new video cards come out before I purchase anything specifically for this game. Why pay the $300-$400 on a new card that performs alright when there should be new ones out near the end of the year that will perform way better. Not to mention drivers that are in the works just for this game and the patches that are coming out. My x600 is playable, so I'm satisfied.

    I guess if you really need that cutting edge performance then you won't mind spending the $1200 or more to buy SLI or Crossfire video cards. This is probably the same peopel who upgrade their desktops every 6 months because there is something else better available. However for the rest of us we should probably wait until the game has 6 months of patches and new video drivers before deciding on upgrading. Experience with HL2 and almost every other game tells me that performance will get better with time.

    i would love to see these benchmarks compared to another exactly the same run but WITHOUT grass enabled at all. everyone and their dog knows that the grass in this game is implemented very badly, and has a tremendous impact on performance.

    the worst part is that the grass is quite frankly FUGLY! complete sticks out like a sore thumb in every scene i tried it in.

    in any case. i'm running a 2.4@3.2 northwood/1gig/6800gt@ultra+/1280x1024,hdr,nograss,noshadows and it plays very nicely for me.

    i would suspect that anyone with anything from the 7800+ & x1800+ families would be extremely happy with the game if they took off the grass and toned down the shadows.

    I like having the grass. Without the grass, it's just yet another game with a flat, green texture representing the ground. That hasn't been acceptable since 2003. I do think the grass could do with a bit more variation (i.e., taller in some areas, shorter in others, more or less dense, etc.), but if the added variation also increased system demands, then forget it.

    Of course, the grass isn't perfect. It doesn't bend around your character's feet/legs; when an object like heavy armor, a sword, a dead body, etc. falls down in tall grass, it can also make it a bit tricky to find. I do find myself disabling the grass at times just for that reason, not to mention shutting it off when there's too much going on and frame rates have slowed to a crawl. Every time I turn off the grass, though, it seems like I've started to turn Oblivion into Morrowind.

    Obviously, we're still at the stage where game engines are only giving a very rough approximation of reality. We won't even discuss how the shadowing/shading/texturing on some faces and objects can look downright awful. We're at the point now where every increase in graphical realism requires an exponential increase in time by the programmers, artists, modelers, etc. as well as an exponential increase in computational power required to render the scenes.

    Wow load up the bullshit. Not only are your framerates strange, but it seems that you somehow did something to make the x1900XTX perform worse than the x1900XT... which is impossible. The XTX bests the XT by at least 3-4FPS in the worst of cases, so we can't even consider a performance decrease to be within margin of error.

    We know all the x1k Radeons best any nvidia card out there now in this game because of the simple fact that SM3.0 was done better on ATI and because of the massive pixel shading power the x1900 cards have.

    I don't see any AA tests as well. You forgot to mention that the game looks like garbage without AA and I know many nvidia users that prefer bloom+AA than just HDR.

    Thanks for wasting my time.

    I'm not sure what benchmarks you're looking at, but only places where the XT comes out ahead of the XTX are in the city and dungeon benchmarks, and for all intents and purposes the two are tied. Due to the nature of benchmarking with a Bolivian (we're not playing back a recorded demo, but instead wandering through a location in a repeatable manner) the margin of error is going to be higher. The minimum frame rates are particularly prone to variations, as you might just happen to get a hard drive access that causes a frame rate drop in one run but not another.

    The most important tests are by far the Oblivion gate areas, and trust me you will be seen plenty of them in real gameplay. Who cares if you get 70 frames per second or what ever in the dungeon if your frame rates dropped to 20 or lower outside? Looking at those figures, the XTX comes out about 3% faster, which is pretty much what you can expect from the clock speed increase. 625/1450 vs. 650/1550... if we're GPU limited (as opposed to bandwidth limited, which appears to be the case with all Bolivian), the XTX has a whopping 4% clock speed advantage. Throw in CPU and system limitations, and you're not going to be able to tell the difference between the XT and the XTX in actual use.

    As for your assertion that the game looks like garbage without anti-aliasing, I strongly disagree, as I'm sure many others do. Just because you think AA is required doesn't mean everyone feels the same. I would take HDR rendering in a heartbeat over AA in this game. That's how I've been playing the game for well over 100 hours. When running at the native panel resolution of my LCD (1920x1200), anti-aliasing is something I worry about only when everything else is maxed out. My point isn't that you're wrong, but merely that you're wrong for saying that many people prefer bloom + anti-aliasing. *Some* people will prefer that, but far more likely is that people will prefer bloom without anti-aliasing over HDR, simply because it gives you higher frame rates.

    At least 2 different "benchmarks" where the XT is ahead of the XTX. Once I see crap like this, sort of makes me doubt everything they say.

    Also we aren't told what settings were used in the drivers for each video card. That plays a huge role here.
