Trouble when running game.

Yeah, I wonder if it's your RAM memory, because 1GB won't run anything these days. Even with 2GB on my laptop, my MapleStory used to lag atrociously. NVIDIA GeForce, well, I think I have another version, but I basically have the same brand, and it's not that great. That might constitute two reasons as to why you are having problems. I wonder if it's possibly an IP block as well.. but it can't be that if you can hear the game's music, so perhaps it IS your memory and graphics-card.

Also, if I may ask, why do you want to play gMS so much? Any specific reasons aside from vMS closing down?
