Ok so you have a x bunch of RAM in your pc , but how do i optimize this for Quake ?

Ok here we go

variabele x = Limit of your MB RAM
variabele a = com_hunkmegs
variabele c = com_zonemegs && com_soundmegs && free RAM for windows etc

This is how it goes:

x / 4 * 3 = a
x - a = b
b/3 = c

So for 256MB RAM this should be:
seta com_hunkMegs "192" //256/4 = 64, 64*3 = 192
seta com_soundMegs "21" //256 - 192 = 64, 64 / 3 = 21,33...
seta com_zoneMegs "21" //Same Value as com_zonemegs
//SOM: 192+21,33+21,33+21,33= 255,99.
