@ funkysourav - thanks for the link and feedback - much appreciated
BTW, here's some point to remember about the mod :
There are THREE sizes to choose from at the moment.
Choose one. (WHICHEVER VERSION YOU CHOOSE, EACH CONTAINS EXACTLY THE SAME TEXTURES, JUST AT DIFFERENT SIZES, SO DON'T WORRY THAT YOU MAY BE MISSING ANY CHANGED TEXTURES)
LARGE (7 GB Unpacked!)
: For those with Overclocked i5 or i7's, Crossfire/SLI, 4GB+ RAM, with Raptors, Raid 0, or better still Solid State Drives. 64 bit system preferably and New Vegas made Large Address Aware.
MEDIUM (4.6 GB Unpacked!)
: For high end PCs- Overclocked i5 and i7 users, with 1GB+ GFX cards, 4GB+ RAM. 64 bit system preferably and New Vegas made Large Address Aware.
SMALL (1.9 GB unpacked!)
: For those with good PC's, who get a good performance on the Default Game and have some power to spare.
3) IMPORTANT: Activate "archive invalidation invalidated" so the new files show up in game. (Also, if you are overwriting a previously installed, different sized pack, THEN TOGGLE ARCHIVE INVALIDATION INVALIDATED OFF, THEN BACK ON AGAIN or the new textures may not show up)
You can activate this in the Fallout Mod Manager Mod (FOMM)
or by using the Archive Invalidation Invalidated mod:
Archive Invalidation Invalidated
Play!
4) Due to the size and number of files your poor PC now has to process, you should probably make New Vegas 'Large Address Aware' (ie. let it use more than 2GB, which it is currently locked to) to give New Vegas more memory access. This can reduce crashing and even give a performance/ framerate boost! Your mileage may vary.
So, I recommend you try this mod:
