The Elder Scrolls IV: Oblivion GPU Performance

Setting Expectations
While we've been used to running high end SLI setups at 3MP resolutions and still getting reasonable frame rates in games, the same is not true for Oblivion. In fact, there isn't a single GPU or pair of GPUs today that will run Oblivion at 1600 x 1200 with everything turned on smoothly. Our highest end X1900 XT CrossFire setup can't even run our most stressful real world Oblivion test at 1280 x 1024 with all of the detail settings set to their highest values. That's right, $1200 worth of GPUs will get you less than 50 fps at less than the highest image quality, and we're not talking about having AA enabled either.
With Oblivion, you've got to set your expectations appropriately for what good performance is. If your frame rate never drops below 30 fps, then you've put together a very fast system for Oblivion. The problem with Oblivion is that while performance may be in the 60 - 70 fps range indoors or while taking a stroll around town, as soon as you engage a few enemies or walk near an oblivion gate your frame rate may drop into the teens. A choppy frame rate really impacts your ability to do things like slice the correct opponent and not someone you're trying to protect. If a video card can maintain a minimum of 20 fps in our most strenuous test (the Oblivion Gate benchmark) then it will do you very well, otherwise you may want to start turning down some of the visual quality options.
Oblivion is also one of those rare games where turning down all of the image quality options not only impacts how good the game looks, but it actually can have a pretty serious impact on gameplay as well. Turning down your view distance is a sure fire way to increase performance, however the lower your view distance is the more difficult it is to spot landmarks you're searching for. You can decrease things like the distance which characters, items and other objects will appear, giving you better performance, but also putting you at a disadvantage when you're looking for a particular item or when someone is about to attack you. With Oblivion it's not all about performance and dealing with slightly blurred textures and jagged edges to maintain higher frame rates, the total experience of the game is very dependent on having a powerful system with a fast GPU.
The Test
Given that we're looking at GPU performance we tested all graphics cards with the same, very fast CPU, to minimize any CPU bottlenecks. In future articles we will look at how the CPU impacts performance under Oblivion, but for now the GPU is our focus. All ATI cards were run on a CrossFire 3200 platform while all NVIDIA cards were run on an nForce4 SLI x16 platform.
The latest drivers from ATI and NVIDIA were used, including ATI's Chuck patch for Oblivion that enables CrossFire support and AA+HDR rendering support. Given the low frame rates that we're talking about already, enabling AA simply didn't make any sense as you will see from the performance results on the coming pages. We would much rather increase detail settings than turn on AA in Oblivion.

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.DigitalFreak - Wednesday, April 26, 2006 - link
Opteron 165 @ 2.51Ghz2GB RAM
Geforce 7900GTX SLI
Check the tweak guides. There is A LOT you can do to make it run smoother without lowering graphic settings.

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.OrSin - Wednesday, April 26, 2006 - link
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.
