Hey, sorry to bother everyone but I'm currently returning to MxO after a 3 year absence.

I'm running the game on a windows XP computer, 256 MB Nvidia 5200 FX card, 2.8 Ghz processor, and heres an issue. I have a weak 512 MB of ram installed and my computer only says that I have 248 to use...even though it knows that my total amount of memory is indeed 512. The game runs, its just very laggy and choppy and I'm just wondering if theres anything I can do to make it run faster?

I have a 54 mbs internet connection, so I doubt its that. Any help would much be appreciated, have a nice day.
