2. Launch it and call up the New Vegas profile
3. Set Anti-aliasing compatibility (both normal and DX10.. I did it for both as I heard the dll fix I'm using for the slowdowns sets the game to DX9 mode) to "0x200100C5"
4.(Optional) For SLI users, I have both of the sli compatibility yokies set to "0x42800005".. dunno if that'll help framerates but I just changed them in hopes that the white specks would go away.. and they did.. probably a coincidence.
5.(Optional) Turn the Anti-aliasing behavior flags to "None"... again this could be completely irrelevant but it works so no harm in trying it. Perhaps someone could advise me on whether setting it to "None" is perfectly fine.
6. Hit "Apply Changes".
And that fixed those annoying white speckle things on the edges of objects in the game when anti-aliasing is enabled.
