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.

    Really? I follow most of this site's articles, and I've never run into this problem.
  • cgrecu77 - Wednesday, April 26, 2006 - link

    this is the article I've been waiting for, I was leaning towards upgrading to x1800xt but wasn't sure.

    The game is easily one of the best i've played (and it's my first RPG, I'm a TBS fan). While it doesn't have the depth and replay value of series like Civ or HOMM, it's still far better than any FPS (can't compare with other RPGs) I ever played.

    Whoever says that the graphics in Oblivion are not the best is just full of b..t or lacks the hardware to turn everything on, looking from the top of the mountain at the Imperial City on a clear moon night it simply breathtaking.

    The gameplay and interface are also among the best I've seen and there are few occasions where I think: "this should have been improved". The inventory system is probably a weaker point, but even that is debatable (it's quite obvious that much thought was put into it but maybe the decisions taken there are not the greatest).

    However, performance is a big issue. My system is middle to upper range (a64 3200, 2gb ram, x850XT) and I can barely play at 1280x1024 with all sliders to the top and without shadows or AA.

    Outdoor I get ~20fps which is ok, actually even excelent considering the huge number of objects rendered (especially grass and trees) - and acceptable since most battles are inside. What I don't get is why I have such a poor performance indoors, there are moments in a heated dungeon battle (especially where there are many fires, like inside sigil towers) where frame rates drops to low teens (from mid 50s). Graphics are average in those building, I only battle 2-3 opponents or less, the map is quite small (since any door leads to loading times )- so I don't get it, how come the game slows to a crawl there. I would consider this an obvious place where optimizations are lacking. Another thing that's missing is a way to alter the grass length (from the game menu, most people only look there to alter settings) and a few other things that were proven to greatly improve performance.

    The hit to performance in dungeons may be due to a mix of having the shadow detail and specular lighting (or filtering?) set too high. I have the same problem with my 6800gt. Especially when I am fighting spell casters. If we are both casting spells, the system crawls.

    Opteron 165 @ 2.51Ghz
    2GB RAM
    Geforce 7900GTX SLI

    Check the tweak guides. There is A LOT you can do to make it run smoother without lowering graphic settings.
  • bollwerk - Wednesday, April 26, 2006 - link

    I also have 7900GTX SLI and it also runs fine for me with maxed settings at 1920x1200. (Athlon 64 X2 3800+, 2GB ram, A8N32SLI) It's obviously not high FPS, but it's also not choppy at all as far as I can tell. Totally playable for an RPG. I'm loving it and I'm glad I didn't get the 360 version. The PC mods are soooo worth it.
  • JarredWalton - Wednesday, April 26, 2006 - link

    But the tweak guides ARE lowering the graphics settings, just in a different way. I'm okay with 1920x1200 at modified details on 7900GT, but there are still times when frame rates drop into the single digits.
  • Yawgm0th - Wednesday, April 26, 2006 - link

    No, they're not. I mean, you can do tweaks that involve lowering settings, but that are tons you can do that improve graphics and graphics performance at the same time.
  • JarredWalton - Thursday, April 27, 2006 - link

    For example? I'd really like to get more graphics quality for less graphics work.
  • kmmatney - Wednesday, April 26, 2006 - link

    I would also like to see the performance without Bloom and HDR. A lot of times, I prefer games without this effect (its often not implemented very well). PLays well on my setup without AA and bloom, and with AF, at 1280 x 1024. Sempron 2800+ @ 2.4 GHz, and modded X800GTO2 running at X850XT speeds. I'd rather play at the higher resolution than lower resolution + Bloom.

    My problem is half the hipe of this game is that you a need a monster system to use it.
    Does any one remeber when a game bragged about the fast that it doesn't need powerful card to play it. Now its just the opposite. No wonder game will not be made for hard core gamers soon. I just can't understand have to pay $400 for a card that only 1-2 games will actually need. When in 6 months that same card is $250 maybe 6 games out might need it. Program in this age are jsut lazy or the products are being rushed. Can we get some optization and have people talk about great graphics on $150 cards.
    As much as I hate consoles I'm leaning to them more and more. They will always the play the game good and mulitplayer support internet support is here (not this game).
    I just hate the UI of most of them.
