Fallout: New Vegas - D3D9 Performance Fix (ATI)
Alternate D3D9.dll which results in better performance/compatibility for users of recent ATI cards by properly configuring FaceGen. Also available is a generator of semi-customized DLLs. See below for which you should use.
Install: Drop this in your Fallout New Vegas directory.
Troubleshooting/crashing:
- Xfire reportedly causes FNV to crash if you are using this
- Using two+ monitors may cause this to crash, use only one monitor
- Yes, it is SUPPOSED to detect your card as an NVIDIA 8800GS. Don't worry!
- Be sure to try the Nvidia version if this one doesn't work:
- Or if you're feeling experimental, grab my beta D3D9Gen from the Files and use that.
Why does this work?
Fallout decides its render path (how it does the graphics) based on two things. The first is the name of your videocard. This is an incredibly bad idea for a number of reasons; Fallout can guess information about your card wrong because of this. This DLL lies to Fallout about what card you have, which can result in somewhat better performance, but it isn't a major issue unless it's drastically wrong, which will cause glitches.
The second (and far more important) thing it bases its decision on is something internal to the DLL; since I'm not the original creator I can't say what else it tells Fallout. From what I've read, it tells Fallout's FaceGen system to use a certain method that generally works much better for everyone. FaceGen is what causes the slowdown when looking at NPCs.
