(updated September 02, 2013)
When you run Oblivion for the first time, the program automatically sets the graphics for you, based on your PC. If you're actually happy with the way the program set things up graphically, then just play the game and don't change anything . . . and you're probably in the wrong place right now, because that's 90% of what this section is about. But if you want to find some ways to tweak up the graphics AND still get acceptable FPS, then you might want to try out some of my tweaks (Oh, I should probably point out that "my" doesn't mean that I come up with all these tweaks (although I did come up with a few of them on my own) . . . "my" refers to my collection of tweaks, that have helped improved both the appearance and the performance of Oblivion on my computer.
My Gaming Computer (opens a new page): What I'm now playing mygames on. (This is a MUCH faster computer than what I initially ran Oblivion on).

Oblivion was released over three years ago, but it can still bog down all but the fastest computer systems - especially when you're trying to run it with over 100 mods installed. Very few people who have a bunch of resource eating mods installed are able to play Oblivion on it highest settings.If you're not happy with the appearance or performance of the game, you can open the option menu and make all sorts of adjustments. Plus there are like a zillion adjustments that you can make in the Oblivion.ini file. (But I'm only going cover a few here)
The trouble is that it's really difficult to improve the appearance and still have good FPS. I tried all sorts of things - some helped my FPS a bit, but most didn't help at all, or even made them worse. Please don't just start changing things, unless you know what you are doing. Every thing that I tried came from suggestions that others had used - but computers and graphic cards are so different. But I finally was able to get the game running fairly well.
When you're playing Oblivion, you can turn on your FPS by doing the following:
FPS are a good way to tell what effect your changes in graphic settingsare having. The higher your FPS, the smoother (less jerky) the game is.
These tweaks will also help to reduce the in-game stutter (jumps), which will make the the game run smoother, even with semi-low FPS.
Things in Oblivion that really cause your FPS to drop: the forest, the 3D grass, rain or snow, shadows, lights, spell effects, NPCs, and the Oblivion gates.
In the beginning of the game, I didn't have any trouble at all. But as soon as I left the prison sewers I found that my game had slowed down a bunch. So I learned how to check my FPS and started tweaking all sorts of things, until I had a playable game.
Updated 3/06/09: Please note that this page was made when I was running Oblivion on my laptop. My newer desktop PC is much more powerful so I'm now running Oblivion at much higher settings than what I've given here (while running over 130 mods).
Please note that these screenshots can't fully show how the actual in-game graphics look - they are just the only way that I can illustrate the differences here. These are all untampered screenshots - my only edits were in reducing the image sizes. The actual FPS are displayed in all the images and I restarted the game after each change to the video settings.
After I installed Oblivion, the program selected the graphics based on my computer. I ended up with the resolution set at 640 x480, with medium textures (and a bunch of other low settings). This is what it looked like:
Reverse view, looking back into forest (same location as above):
But this resolution looked horrible on my computer Trust me, it looks much worse in the game, when it's running at full screen size. Everything gets stretched sideways to fill my 15.4" wide screen - which made my Wood Elf look fat!
This is 640 x 480 on my wide screen: My Wood Elf at 1280 x800:
I tried playing the game in a window at the other resolution settings. In a window, I actually got higher FPS at 1024 x 768 than I had at the lower resolutions with full screen. And this did fix this stretching problem and it looked much better than at the lower settings. But playing in a window just wasn't the same as full screen.
The only wide-screen setting for this game is 1280 x 800, so I tried that (Oblivion now supports additional wide-screen resolutions):
1280 x 800 (FPS=9)
This looks much so much better. But upping the resolution dropped my frame rates down to a non-playable level. In the forest, they went down to 4 FPS, which is a slide show. I could barely control my character, which wasn't any fun at all! It was pretty, but completely unusable. Bummer!
The Distance Slider Option
Ok, so now what? I really wanted to use a wide-screen resolution, but my one choice was too much for my computer. Hey, what if I try backing off the view distance slider a bit? That's what I had to do in Morrowind to get playable fps on my older computer. So, while still in the game, I hit <ESC>, picked Options, then Video, and scrolled down until I found the View Distance slider - when I slid to the left just a bit. This is what happened:
1280 x 800 - with fog (FPS=11)
Not exactly what I was hoping for! It turns out the turning View Distance down even just a little bit, turns off Distant Land completely, by replacing it with a thick fog.
1280 x 800 - with fog (FPS=11)
My FPS only went up a little, which was still barely playable in the forests, and I hated all that fog. . . bummer again.
Cutting the Grass
So then I went back into the Video Options and tried
moving all the other sliders around. I turned all the shadows
off, which helped some. And I decreased the Grass Distance way
down, which helped a bit more.
This was the result:
No grass, but now I'm getting 11 FPS at 1280 x 800 - and that's with Distant Land turned on!
Ok, I can live with this, but I'll miss all the 3D grass.
This is the result:
Thinner 3D grass, but 14 FPS at 1280 x 800 at higher distance settings, shadows, and reflective water!
(Note: this screenshot was taken after I installed a couple of graphic MODs - see my Oblivion MODs Page.)
Here are the side-by-side comparisons:
From default settings of 640 x 480 at 12 FPS to 1280 x 800 wide screen at 14 FPS
