Sorry for my bad english:
Do not know if this is of interest, but I have not had major problems with the game,
but realize that it is very annoying for those who are suffer to get the game to work.
Therefore, I asked myself, why people bothered with Fallout NV, may be mod ..make trouble, the load order of mod?!??
or are there things we have installed on machine?.. I allways play Fallout NV offline mode...steam
'll Admit that I had crashes before I removed the codex packs,
after that I only have a few crashes that I think is mod related.

Btw, Will there be any DLC for Christmas .. Does anyone know?

This is my machine:
AMD Phenom II X4 965 Black Edition
ASUS Radeon HD5970 2GB

Something must be wrong with your copy or pc then!

Yes, if you have an X-box. Otherwise, no.

I haven't had any real issues playing either, just a few quest bugs here and there. No hardware issues to speak of.
