Killer Doom 3 Performance Tweak

This is an other ingeniousness that aims at making Doom 3 access its assets faster: up to 10 times according to the author! And no, it won't tell you to decompress the PK4s and recompress them back thereafter.

To my opinion, this is the best way to achieve that goal because the original PK4s will be left intact. However, you will need quite a lot of free space on your hard drive. Actually, thinking about it, all depends on what data you want Doom 3 to access faster ...
