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.

    Well it will work with other games that use D3D9.dll but not so good as with Skyrim.

    It was specially optim. for Skyrim, well tho you no longer need it for Skyrim if you have higher version than 1.3 of the game.

    Hey Meritus, just want to let u know, I downloaded ur mod from NExus and I am seeing about + 14 fps from this. I have always played with the max settings and with ugrid 7 and the Skyrim HD - 2K Textures mod(+ the official 3GB High textures mod), where I mostly got from about 48 - 57 fps, though in the most graphically intense places it would go down to 30 fps, like in Riverwood. Now Riverwood is 44 fps minimum.

    Basic Specs:
    Graphics card: ATI HD 6970 2GB
    CPU: Intel Core i7 X980 3.33GHz
    Motherboard: ASUS Rampage II Extreme Republic of Gamers
    Ram: 6GB
    OS: Win7 64bit

    Launcher is crashing for me, I am using 1.2.14 launcher and 1.1.21 TESV with a Nvidia 9800GT - 285.62 drivers, windows 7 x64. I have tried running both launcher and exe as admin, and launching with and without esp's. Game functions properly as soon as I remove dll.
    I am not using xfire or sli, I have the most up to date directx end user runtime (confirmed just now).
    Thank you for the work you have put into this mod :D, any help you can give me would be greatly appreciated :)

    Looks like somebody uploaded my mod again on NEXUS and named it
    "Gigantic Skyrim FPS Performance Patch"


    File works with Skyrim patch 1.3.7 aka patch R4 (Tested by me)

    Results of testing:

    Vanilla + R4 = Whiterun (top stairs) = 34 FPS (HIGH Settings)
    Better Performance = Whiterun (top stairs) = 31-33 FPS (HIGH Settings)
    R4 Update + Better Performance = Whiterun (top stairs) = 33-37 FPS (High Settings)

    Yeah, sorry about late reply about that, i totally forgot about this =D
    Lmao isn't it?

    I think the change in graphics adapter to 8800 GS does cause issues with my GT 425M Optimus card. I'm not exactly sure why but since it changes the adapter within the launcher, priority goes to the integrated card, Intel HD Graphics 3000, over the GT 425M. When I try to go into the nVidia control panel to Add TESV.exe to be used with the GT 425M, it has no affect; nothing gets added at all. This only happens with the d3d9.dll file in the folder. I've tried changing the adapter from 8800 GS to GT 425M in every ini file I could find but it still has no affect. It's only when I remove the d3d9.dll file from the folder that it begins to detect the GT 425M again. If I can find a way to add TESV.exe preference in the nVidia control panel it might be okay to leave the d3d9.dll in the folder even with the adapter set to 8800 GS. Maybe the solution is in beta drivers but I'm not entirely sure.

    I'm assuming all nVidia cards with Optimus are having this issue.

    If anyone knows a workaround let me know.
