Fix for incorrect Videocards, D3D9 errors and Renderer related crashes + possible performance gain
By Honor Miku
Fix for:
-Incorrect Videocards set in the launcher
-D3D9 Errors
-Renderer related crashes

A few clicks will save your game

+possible performance gain
This guide will show you a simple tool which may save your game.
This tool is mostly selfexplanationary, but sometimes people wont understand it.
I will try to explain and guide you.
Please notice, everything i write here is purely from experience using this tool.
The Tool
The tool was originally created for Fallout New Vegas.
Since Skyrim and FNV share the same base engine, the tool can still be used.
You need a Nexus Account and you need to download "D3D9Gen b3" manually not via the manager.

How it works in detail, is explained by the original creator, AlekseiVasiliev; the kudos and credits for creating this go all to him. Not to me.

The tool will create a custom d3d9.dll. This may interfere with any mod, that adds an own d3d9.dll, most likely an ENB mod.

A user reported, that the .dll also increases his performance. This proves what AlekseiVasiliev said about increased performance.
How to use the tool
Once downloaded you need to unrar/unzip/whatever just get the files it. You should place a folder called "D3D9Gen b3" on your desktop with all the files from the archive in it.

Depending on your system:
-x32 systems use D3D9Gen (.jar)
-x64 systems use D3D9Gen_x64 (.jar)

Run (Double click) the .jar you need/want.
You will see a small window with 3 options:

-Set videocard by a list
---The list is pretty small, but if you are lucky you may find your videocard already. If so, skip to the
--- step "Once created".

-Set videocard by text
---You need to write down your videocard.
------ Nvidia GeForce 7900GS
------ Nvidia GeForce GTX 660
------ Nvidia GeForce 7800 SLI
------ Ati Radeon HD 2350 Series
------ Ati Radeon HD 2400
------ Radeon HD 6800 Series

---------- You need the exact name, the examples here and in the tools list should be enough to find
---------- the correct name. If you make a mistake you can redo the file, dont worry.

-Set videocard by text enables the option "Detect my card"
--- 3 modes are given: Fast, Medium, Slow
--- the modes will autodetect your videocard, the slower the more precise. This may not work if
--- if you have an "Intel HD 4000", or similiar, and a dedicated video card. This may only detect
--- the Intel card.

If you found your videocard, just click on "Generate DLL"

Once generated, you will be notified and the file will be placed in the folder, where the generator is. This should be your "D3D9Gen b3" folder on your desktop.
The generated d3d9.dll needs to be placed in your skyrim install folder, where tesv.exe is.
The default folder is:

If you placed the .dll in your skyrim folder, check the launcher. It should have your videocard rehistered correctly. You may need to delete "rendererinfo.txt" from documents/mygames/skyrim folder. This .txt will be recreated.

Your game should work fine now.
ENB fix by Diana
To use with ENB you can edit the ENBLOCAL.ini file to be like this


Where d3d9_amd.dll is the name of the dll file generated in this guide. Then you get both!
Last words
Remember, this guide is written from experience with the tool.
If it doesnt work, dont blame me or AlekseiVasiliev.

If you find any grammar mistakes, meh me no english.

Any suggestion regarding improvements are welcome, if there is a large demand for images i will add some, even though the tool has only one window and everyone should know at least how a Windows looks.

Now happy skyriming, fight well or die well.

PhrenoPSycho Nov 5, 2016 @ 4:34pm 
it was the same but now i made ENBLOCAL read only, but still returns to my integrated grapchics :(
Honor Miku  [author] Nov 5, 2016 @ 4:26pm 
can you check if the ENBLOCAL file was reset?
if so, change it according to the fix and set it to read only
