i just noticed today the game was using ~2Gb of memory per instance of EQ.. this seem extremely high.
did a full reboot and it looks a little better. Still seems really high for such an old game. This is with the Least Mem usage setting. first 3 are in EoK zones others in older zones.
I believe there is a known memory leak issue if the game is left running, and not rebooted periodically. This may be related if you keep your system up and running awhile.
