On the .dll fix:
"temo" works great from my experience tonight.
Tweakguides.comI've been receiving a lot of emails about this, so I thought it important to finally speak out about it. An unofficial 'fix' to performance issues in Fallout: New Vegas has been doing the rounds for the past week as some sort of global solution to all problems. I do not recommend this D3D9 Fix at all, as it causes Fallout: New Vegas to falsely redetect your graphics card as a lower model, and in turn use a lower shader package. It can reduce image quality and cause a range of long-term problems. A much better solution is to use the ToggleEmotions (temo) console command in each Fallout: New Vegas session to temporarily disable facial emotions on NPCs, thereby removing the major source of the slowdowns which may occur in areas where there are several characters. This method will not reduce your image quality or cause other potential problems. This is also a good time to remind everyone that PC gaming does not involve any quick fixes. If you're having performance issues in Fallout: New Vegas or any other game, the correct solution inevitably involves properly optimizing and maintaining your entire PC, along with research and intelligent tweaking of the game, not just grasping at the first quick fix that happens to come along. Additionally, official patches and driver updates resolve many of the legitimate problems, so some patience is also involved.
