Hi. I found a way to boost New Vegas performance. It may not work for everybody, but it certainly worked for me, and even fixed some things that also happened in Fallout 3. It fixed the delay when you go into vats before the numbers showed up. Overall framerates have gone up. Here's the fix: Download NVMM: http://www.newvegasnexus.com/downloads/file.php?id=36901 When it asks if you want to assosiate BSA file types with the program, make sure they are left checked. Now, go into your New Vegas Data folder where you normally install mods. You'll find the vanilla files have the FOMM icon next to them. E.G. Fallout - Meshes.bsa Double click on each of these, and choose "Extract All", and choose the New Vegas Data folder. Do this for all of the BSA files. Now, cut and paste the BSA files into a folder named "Backup BSA Files" anywhere on your computer, in case this doesn't work for you and you want to put them back. I'm not sure why this worked, as I know nothing bout BSA files. But it worked for me and hopefully it will work for others too.
