My brother was playing Doom 3 and he decided to extract all the pak4 data from the install dir. It made the game dir a whooping 4gb, but he gained about 20fps on his shitty rig!

I don't see how this would work anyway - I mean, paking the files (aka data compress) should be efficient enough to begin with, and you would think that by just having the files laying there it would offer no performance increase. (But, some games like Far Cry still opt not to have this level of compression, and their install dir is well over 3gb - I thinks?)

My comp is extremly shitty, I was only getting about 10-15 FPS before, now I am reaching 25-35. Everyone should do this.

dzjepp, If I do the same to the other pk4 files, will it increase even more?

Nice find btw

The sideeffect is that you can't play mp since mp will get confused? - but you can always have 2 dirs one with the paks (for mp), the other extracted (for sp).

Just extract these:

pak000.pk4
pak001.pk4
pak002.pk4
pak003.pk4
pak004.pk4

Some guy made a batch script for winrar/winzip that will make this easier (as if it already wasnt )

thanks

One, if you didn't defrag the drive that it was installed on before you installed it, then this could result in small, less-fragmented files than the large pak file would have been (and when you defragment, watch the diagram to make sure there's enough contiguous unallocated space to fit Doom 3 into).

The overhead of the zip file should be minimal -- the files have a table of contents, so they don't need to be loaded before specific files can be extracted -- so focus on the defragmentation first.

I even defragged before and after, and still no difference. Funny thing with the tweak is my timedemo would stay locked at about 32.5 even after 3 consecutive run throughs. While using the pak4 format I would sometimes run the timedemo 3-4 times and each time would yield a slightly different result (higher/lower).
