In this guide I will help all you idiots who don't know how to optimize Oblivion so it can run on your low end systems.This guide may not work for all low end systems but it will work for most. Anything under 1.8ghz processing speed should leave now though and stop reading.
Step 1 : The Programs.
What does this shit do? ******* sorts your mods out into the correct loading order so your shit don't get ****** up, make sure you also download the updated master-list as well. Dump it into your Data folder in your Oblivion installation directory and don't touch it for now.
This is the Oblivion Mod Manager, straight forward enough for most people. It also offers a feature to make your own OMOD files as well as install them.
This is a straight forward installation as it comes in .exe form so you shouldn't be able to **** up.
Oblivion Script Extender, this is needed for some of the optimization mods. Once you've downloaded it shove it into your Oblivion directory.
Download the latest build here:
Step 2 : The Mods.
If you've never installed Oblivion mods before they usually come in one of two ways. The majority of the time they are manual install which would just mean dumping the files in your data folder located in your oblivion directory. The minority of the time they appear as OMOD files, to install you just double click them if you already have OBM installed. To enable OMOD files, make sure that the check-boxes within the right of Oblivion Mod Manager are blue and not green.
Unofficial Oblivion Patch:
This is the patch Bethesda should have made, it fixes a lot of CTD issue and overall improves game play through out. If you also have Shivering Isle be sure to download the Unofficial patch for that as well:
Shivering Isle: http://www.tesnexus....le.php?id=10739
Low Poly Grass:
This mod significantly improves frame-rate dramatically by cutting down on the polygons used on the grass models. It comes in 3 modes, Low Poly Grass, Low-low Poly Grass and Alt Low Poly Grass. If you have Shivering Isle just download the SI Low Poly Grass version.
Short Grass v3:
Decreases the size of grass once again improving fps. Doesn't conflict with the above mod.
Optimised Distant Land MAX:
This changes the distant land meshes to be less complex. It comes in two versions 50% optimized or 75%.
Quiet Feet MAX:
Reduces the sound file used for walking/running/horse galloping sound effects. The default sounds can lag some older systems.
This mod removes the parallax/displacement shader from about 500 different .nif files used in Oblivion. It replaces it with the standard diffuse shader that nearly everything else in the game uses. Why? Performance! On my machine, I gain an average of 5 FPS when playing in areas that use parallax shading with this modification. Also, movement in parallax-disabled areas now seems smoother to me. However, the trade-off is that these surfaces now appear very flat, and lose a bit of their previous shiny-ness. But, this is the nature of performance tweaking.
Oblivion PolyGone Overhaul:
Oblivion PolyGone Overhaul (OPO) is an ambitious project to reduce Bethesda overly generous use of polygons on in-game objects with little to no loss in quality.
Oblivion Script Optimization:
This mods goal is to give a better performance by optimizing the scripts found in the game. Every frame hundreds sometimes thousands of scripts run in the background, this requires a lot of CPU processing power. Using this mod the CPU will be able to run them with less calculations, but accomplishing the same goal.
Purge Cell Buffers:
A simply little mod that will purge the cell buffers, and what does purging the cell buffers mean? It means cleaning out all the cached data that is no longer being used. It comes in two versions, purging after loading screen and during cell changes. Recommenced to use loading screens option due to the cell change option can interrupt npcs talking.
The aim of this mod it to improve performance (FPS) without quality loss by optimizing large meshes used through out the game. Comes as a .exe for easy neck-beard access.
CaptNKILLs NonTiling Texture Mod:
Oblivion uses a lot of tiled textures in game, this mod removes them and replaces it with one big texture instead of thousands of smaller textures.
Reduces loading and increases frame-rate.
Step 3: Changing values in your .ini file.
The Oblivion.ini file is located within My Documents/My Games/Oblivion
Before we start, I suggest making a backup of the Oblivion INI file
Change these to 1:
Change this to 5:
Set these to 9 and 10:
Now, for 1 gig of ram change these to 6 and 72; for 2 gigs or more, 16 and 102:
uInterior Cell Buffer
uExterior Cell Buffer
Change this one to 52428800:
And change all of these to 1:
This variable is default at 40. It controls how many clusters of grass there are in grassy areas. The higher the number, the less dense the clumps, and a greater FPS. The suggested change is to 120, but I put mine up to 200, and my FPS jumped by 5 FPS:
Step 4: Tying up the loose ends.
Well done if you made it this far you're pretty much done. The very last step you will need to do now is go to your data folder and hit the Boss.exe and Boss.bat file, these will sort your mods into correct loading order so your game doesn't crash. Now one last mod to install and you're done.
Download it and run it, this will remove the need to update your Archive Invalidation manually so your .BSA files will all be working correctly.
Now all that's done open up Oblivion Mod Manager make sure all your files are checked the ones on the left and right.
Btw didn't make this.
