This is a compilation of many High-resolution textures for fallout 3.
It vastly improves the visuals of fallout 3 without changing the overall "fallout 3 look"
A fast computer which can handle everything on ultra-high is recommended (Otherwise you will experience studdering)
When it extracts it becomes twice as large!
Navigate to "C:/ Users/ Username/ Documents/ My Games/ Fallout3" (or equivalent on XP)
Open Fallout 3.ini
Find the line "bInvalidateOlderFiles=0" and change the 0 into a 1
Now navigate to the fallout 3 install directory and copy the contents of this pack and overwrite if prompted.
