About Skyrim Better Performance

[User @nix9862 was not allowed to upload my file to nexus, please retain from downloading it from there.]

Fus Ro Dah! You run oblivion on highest settings? Skyrim only on High or Medium with annoying freezes or lags? This file is for you! You can jump from Medium to Ultra in less than 1 minute!

Quick Update - 3/25/2013

Skyrim Better Performance works now with LATEST version of Skyrim [5 - 7 FPS Gain]**


I was encountering lags on High settings with old .dll file, So i decided to make new one for Skyrim with big succes mostly because the most problems in Bethesda games had same issues that caused FPS drop. Currently im playing on High settings without any freezes or lags etc. Before i used this dll. my auto detect settings set game to MEDIUM quality after repleacing .dll auto detect settings set game to HIGH quality. Also my FPS went up over by 10-15 So this is really very much.

Additional informations:

This works only with Nvidia cards. It allows transparency AA so trees and grass will look much better if you have AA turned On. But i highly recommed to turn off AA and enable FXAA (Better performance)


1. Download file. 2. Make backup of your original d3d9.dll file - IMPORTANT 3. Copy d3d9.dll File to your Skyrim folder. It goes in your regular game folder where Skyrim.exe is located, not in the "data" folder with the mods or other files/folders.

If you placed .dll file in right place launcher will re-scan settings, and you will have to set them again.

Known bugs:

- Launcher Bug - d3d9.dll will change name of your Graphic Adapter in settings from (example) Nvidia GeForce9600GT to GeForce 8800 GS, This really doesn't matter. - Might crash with 2 monitors or more. - Many peoples might get crash with Crossfire or SLI enabled. - Usually (but doesn't have to) crashes with XFIRE possible fix for this - In Xfire go to Tools>options>'game' tab and click on the checkbox "Disable Xfire in game"


1. It does not change any files! Just delete .dll file you downloaded and place the old one if you maked backup of course if not you will have to download original .dll file for Skyrim or reinstall game.


Note: this works no matter ENB mods are also present or not. Examples of non-ENB d3d9.dll-based mods: Standalone SMAA, FXAA Post Process Injector.

1. Rename other d3d9.dll to, say, d3d9_other.dll

2. Edit HiAlgoBoost.ini so that the part of [PROXY] section looks as following:


EnableProxy_d3d9 = true ; Can be used to load Standalone SMAA,... ProxyLibrary_d3d9 = d3d9_other.dll


- Make sure you are running the launcher or .exe shortcut as administrator if you have crash when launching.

- This isn't lowering your Graphics.

- Some peoples asked if it will work with AA turned on? Answer: YES it will work however it works much better with FXAA (More FPS / almost the same graphics quality)

- If you don't have d3d9.dll in your game folder don't worry! Just place my .dll in game folder and if you will want to uninstall it just simply delete it.

- I highly recommend to lower Anisiotropic Filtering because it might cause freezes etc. pretty much.

- Mod might don't work on some Graphic Cards from GTX series and others.

- If you have issues, try updating your official DX runtime first from Microsoft, a quick google search for "DirectX End User Runtime" will get you what you need.

- DX is card/driver agnostic, so it should run on any card, though the particular optimization in this likely favors older nVidia cards of the pre G200 cores, so 9000 and 8000 series. If you have performance issues, instead of using this mod turn off AA and use FXAA. In the game launcher you can find this advanced option. It is a post process (after rendering) algorithm that removes jagged edges without much loss of fidelity or framerate.

UPDATES: 1.1 - Fixed up few things. 1.1 - Supports now Skyrim Latest Patch (Dragonborn)

Enjoy! Meritus aka meritus335.

Works with most Nvidia Cards.

    Thanks so much, this made my skyrim way faster!

    Can this not be installed with the curse client ?

    Hi there, I'm using HialgoBoost and I want to use this d3d9.dll

    I tried to just replace the d3d9.dll, but as I expected the new d3d9.dll was operational but HiAlgo was not working.

    I also tried to rename the new d3d9.dll to d2d9_nolag.dll and enabled the proxy in the HiAlgoBoost.ini, but when I started the game it was like nothing changed just HiAlgo working...

    I could really use some help, with this d3d9.dll I get +10fps but without HiAlgo FPS drops when i'm turning or moving the mouse really fast ! Thanks for help !

    This looks to be nothing more than the DX9 injector that comes from the SweetFX package. I suggest people look it up if you want to obtain faster or better graphics on most games (not all, as some games are just that well done ;). It also does DX10.

  • #109

    Do you realize this file was created before SweetFX was even released for Skyrim and it works different?

    And this file does not increase/decrease visual quality.

    Thanks for the reply, I did what you said but it isn't a d3d9.dll it's d3d9 it's something else. When I place that in Skyrim's Direct it doesn't work. When I was continue searching I found your same exact mod but I was able to download it with winrar, I placed the d3d9.dll file in my Skyrim direct and when I start the game I immenetly get a black screen I can't see the logo but I hear the music in the backround. Can you help me with that? Message ASAP if you can.




    Thank you, OlafTheKing

    Hello there Meritus335, A while ago I downloaded your mod and I have to say it was amazing. But sadly yesterday I accidently deleted the D3D9.Dll File. So I came back here and I tried to download your mod. Then when I clicked download all of a sudden it asked what I want to open it with *It never asked that before* so I searched my computer for Winrar I found it then I clicked open. Then it didn't work. I'm so Pissed because I was running on Ultra High with 60 FPS and I just bought Dragonborn too. This really sucks. If you can please reply ASAP if you can.



    Thank you, OlafTheKing

    When downloading click "Save file" and save it on your desktop.

    WinRaR is not required, all you have to do is just download the file, save it on your PC and place it in Skyrim Directory.

    I installed Skyrim with Steam, and this DLL doesn't seem to exist there. I've got it in other various Steam games, but not in Skyrim. Can I still just plop it in with the exe?

  • #104

    Everything is in desc.
