Soyo 1.3 ghz, old Voodoo 3 Video Card, Win98 OS, old Esolo sound card I think (works well enough - no sound issues), 188 MB ram, little 4 gig hardrive. Never had problems with it before working with any of the hardware. Only programs I occassionally have running with it is cacheman and netlaunch (auto-dialer) and some scripting programs for MajorMUD (online text game for those of you not familiar with it). Far as I've been able to tell none of those programs are at fault - but could easily be wrong. Cacheman says my memory usage is about normal when I come out of the game, but windows says differently and acts differently. At first I figured it might be the new models in tactical combat, but started up a game fresh, quit after maybe 200 turns when no combat had taken place and was already down like 20%. Try to open control panel when it's at it's lowest and it gives me the "Low Memory - Close Some Programs" message. Closing programs doesn't do anything, it's just like the memory's been eaten up. Is weird man.
