How to use the 3Dfx Patch
* Please note that this is a Beta release of the 3Dfx patch. 
There may be a couple of little glitches and the Mip Mapping 
is still to be optimized (see below). The final patch should 
be up in a few days. We kindly ask any third party FTP and 
Web sites not to copy this Beta patch to your sites until 
we release the final version, we want to make sure that when 
it is finalized only that copy is out there. Thank you for your 
cooperation.
* The zip file contains a file "tomb.exe". This needs to be 
placed on your hard drive in the directory where you 
installed the game. By default, this would be c:\tombraid. 
Don't worry about overwriting the original tomb.exe, you 
have a copy on your CD.
* Mip Mapping has been implemented, its purpose is to make distant 
objects more clear. It can be turned on/off in the game by hitting 
F4 (in-game) or clicking on the sunglasses icon in the menu rings; by
default Mip Mapping is set to ON. We are still optimizing this routine 
and as a result when you start the game you will see a black screen 
for up 2 minutes after the opening FMV. Your system has not crashed. 
In addition, if you play w/ Mip Mapping on about 2 megs or so of info 
will be saved in your TOMBRAID directory after each level. If you wish 
to turn mip Mapping of, use the sunglasses icon. Your selection will 
be saved as well as applied, ie when you play another game, Mip Mapping 
will remain OFF.
