1. CRASH/LAG PROBLEMS[/u]
This "ffdshow" thing keeps screwing up the gameOne of the most common problems is that a program called "ffdshow" will show up and make many copies of itself while playing Oblivion, slowing down performance by a lot. This is caused by DefilerPak. To fix this, either uninstall DefilerPak, or go into Start -> DefilerPak -> Audio Options and disable Oblivion.exe. You need the latest edition of DefilerPak to do this, you can get that

I crash sometimes and it gives me an error message about "mpeg2dmx.ax"It's just an old system file. Go find the file (don't know where it is, use Search or something) and rename it to mpeg2dmx.ax.old
This should fix the crashing.
I have keyboard and/or mouse lagIf you're having keyboard lag, go into My Documents\My Games\Oblivion\Oblivion.ini and change
bUseJoystick=1 to
bUse Joystick=0 (it automatically goes to 1 if it detects a joystick)
If you're having mouse lag, turn off self shadows.
The sound is stutteringDoing this will manually disable hardware sound acceleration. Go into Oblivion.ini (My Documents\My Games\Oblivion) and change
bDSoundHWAcceleration=1 to
bDSoundHWAcceleration=0Some people have reported this fixes the sound stuttering.
Another solution someone has found was renaming the Battle music folder in Oblivion's data files, effectively disabling it. Of course then there's no battle music but then the game doesn't get choppy. Bethesda or Creative or someone should have a fix on this pretty soon.
I get horrible horrible lag if I even so much as look at a gate of OblivionThis is a temporary fix. Try turning off vsync. This is kind of annoying in some regards but seems to fix it.
The starting dungeon is real laggyGo into Oblivion.ini (My Documents\My Games\Oblivion) and change
bDoSpecularPass=1 to
bDoSpecularPass=0. This will turn off the shiny walls in the starting dungeon. This might improve the performance by a lot.
WARNING: This WILL crash the game at some points, such as Jauffrey's House. To stop the crashing, change it back to 1.
2. QUALITY TWEAKS[/u]
Is there a big list of a lot of Oblivion.ini tweaks somewhere?http://www.tweakguides.com/Oblivion_1.html'>Yeah check it out.
Shadows look really weirdIf you are seeing stripy shadows across the models that look kind of like
http://random-m.com/images/1920299970_stripe.jpg'>this or
http://random-m.com/images/1041064221_uglyshadows.jpg'>this, then turn off self shadows to fix it.
I can see far away, but the textures are really blurry and everything looks like crapThis isn't a bug or anything, Bethesda just thought it looked fine for some reason and shipped it like that. There's no official way to fix this yet but some smart people have figured out a temporary fix. Follow these instructions and make

http://img468.imageshack.us/my.php?image=f542870dc74gr.jpg'>this (sword not included).
http://www.elderscrolls.com/forums/index.php?showtopic=282542'>Here is a possibly better set of instructions.
Go into Oblivion.ini (it's in My Documents\My Games\Oblivion) and change this line (btw, this increases load times.):
Set uGridsToLoad = 10 (5 by default)
This does mess up water reflections a bit. To somewhat fix the water, change this:
uNumDepthGrids = 1 (it's 3 by default)
By default, the water only reflects the land. Inside the ini you can change it so it reflects all trees, static objects, actors, and other miscellaneous objects (all default to 0):
bUseWaterReflectionsMisc=1
bUseWaterReflectionsStatics=1
bUseWaterReflectionsTrees=1
bUseWaterReflectionsActors=1You can also mess with the tree settings, changing the maximum distance real animated trees can be placed (the variable is fLODMultTrees). Doing all this will lower your FPS by a considerable amount, it's up to you if you want to do it.
Some textures are strange, like flat white heads or maybe your sword is bright greenYou probably do not have enough video memory to handle all the textures. So sorry. To fix this, try lowering the Texture Size in the game options.
I'm lagging outside, and don't care much about what grass looks likeIn Oblivion.ini, these are for the grass draw distance (I don't know what this stuff means because I don't have the game but read that guide)
[Grass]
iMinGrassSize=200
fGrassEndDistance=10000.0000
fGrassStartFadeDistance=5000.0000READ THIS >>>>
http://www.elderscrolls.com/forums/index.php?showtopic=283055'>More detailed grass info here - grass is a big FPS hog so read up <<<< READ THIS
Read this if you have a Nvidia cardYou probably want to install
http://downloads.guru3d.com/download.php?det=815'>Coolbits which is an enhancer for Nvidia's Forceware drivers. Some people have reported that using this nearly doubled their framerates with absolutely no hit in performance. After it's installed, to unleash the awesome power of Coolbits, go into Display Properties (right-click your desktop and click Properties) -> Settings tab -> Advanced -> GeForce * tab -> Performance and Quality Settings -> Additional Direct3D Settings. Set "Max frames to render ahead" to 0 (default is 3).
A PM I got posted:[/i]
Hey, about Coolbits. You should add in that post that you need to turn off Vsync to get that tweak to work. Otherwise it does nothing.
And the main effect that tweak has for me is getting rid of that awful mouse lag, which you may also want to mention.
Other ini thingsI don't know if any of these work or what they do, use them at your own risk.
1. Go into Oblivion.ini and look for [OPENMP] and change the values to what you see here:
[OPENMP]
iThreads=20
iOpenMPLevel=20
iPreloadSizeLimit=1000000000This has been reported to give a small FPS boost. It might be a bad idea to do this if you don't have a lot of memory.
2. This probably only works for cards with Shader 3.0. Anyway, go into Oblivion.ini and find
bAllow30Shaders=0 and change it to
bAllow30Shaders=1. This means it wasn't using 3.0 before but now is and has been reported to give a major FPS increase.
3. OTHER[/u]
How do I disable those dumb startup movies?Go into Oblivion.ini (if you forgot, it's in My Documents\My Games\Oblivion) and change these lines:
SIntroSequence=bethesda softworks HD720p.bik,2k games.bik,game studios.bik,Oblivion Legal.bikto
SIntroSequence=SMainMenuMovieIntro=Oblivion iv logo.bikto
SMainMenuMovieIntro=What video card should I buy? HELPhttp://www.elderscrolls.com/forums/index.php?showtopic=270923'>Click here for a very useful ranking of many many video cards, a much more detailed set of specs, and other miscellaneous important bits of info if you're playing the PC version.
How do I drop things?!Shift-click in inventory. Shift-clicking does a lot of things you might not expect. Try it in other situations!
Can I use HDR and AA at the same time?No. It is unknown whether this will ever change. Yes I know rthdribl lets you, but Oblivion won't, we don't know why, stop asking.
update: Ati has released an update that lets you.
Does defragmenting help?Yes, run a defragment before you play, preferably right after installation. I like Raxco PerfectDisk, it has a 30 day free trial, but normal ol Windows defragment should be okay. Some people have reported that defragmenting got rid of a ton of stuttering, some people say it does nothing. It can't hurt.
How do I find out what my FPS (frames per second) is?Open the console (press ~) and type tdt and press Enter. Hooray FPS. Also you can use Fraps which is free and does a lot of other things.
How do I take screenshots?Go into Oblivion.ini (if you forgot, it's in My Documents\My Games\Oblivion) and change
bAllowScreenShots=0 to
bAllowScreenShots=1 and use the PrintScreen key ingame to take screenshots. Images are stored in the Oblivion directory as BMP files. This may or may not work with bloom + anti-aliasing.
