BTW, are there any High Def Texture packs for NV yet? The Gamebryo engine is so dated and definitely looks like it. I see 4Aces Hires Texture pack (a massive 4.5 GB altogether), but that's about it.
There's http://newvegasnexus.com/downloads/file.php?id=38196 and http://newvegasnexus.com/downloads/file.php?id=39755. That's what I have installed.
There's also a http://newvegasnexus.com/downloads/file.php?id=35645 to get NMC's texture packs from FO3 in FNV, provided you have the files.
I think there may be one more aside from 4Aces but can't find it.
