Memory settings were put in a separate file to be able to add more memory config sets. That way you can easily choose the set that suits the amount of memory your computer has. This file contains three sets, one for computers with 128MB of RAM, one for computers with 256MB and one for computers with 512MB. Some people have more RAM than that, but it is questionable whether RTCW really benefits from allocating it even more RAM.

By default memory allocation is set really low to make sure RTCW is compatible with PC's that are low on RAM. However, most gamers have plenty of RAM in their machines. This makes it possible to let RTCW use more memory than default. Actually, if you are serious about gaming it is more than possible, it is mandatory. More memory means a significant performance boost.

As a rule RTCW should not use more than 3/4 of the total amount of available RAM. You specify the total amount of RAM through com_hunkmegs. Both com_zonemegs and com_soundmegs take a share out of the amount of memory specified with that setting. Of course there is no reason to let RTCW use less than 3/4 of your RAM either... Below are several memory allocation sets. Each set is optimized for a specific amount of available RAM. Place "//" for sets not used. Remove "//" from the set you want to use. Red's computer has 512MB of RAM and you'll see this reflected in the config. These sets were found on HighBoy's Home of Wolfenstein and slightly modified by Red.

You'll probably notice that the maximum value used for com_soundMegs and com_zoneMegs is "32". This is because higher values do not really have an effect. If you have more than 512MB of RAM and want to allocate more memory to RTCW than is specified in this config, just increase com_hunkMegs. It makes no sense to increase the other two memory settings.
