I have halo 2 and a dell 531 inspiron. Its VERY SLOW and i was told there were speed tweaks you could do to a computer to make it faster so halo 2 could run fast. i have the MINIMUM requirements for this. the bare minimum. Basically i have 2 gb ram and a pitiful Graphic card. 6150 N vidia Geforce. anyone know how to tweak the speed of this computer? And also: I have a wifi adapter for my wii/ds/psp and i dont know how to set it up so i can use it. I have the instructions and they confused me i dont know if im supposed to bridge or something. if i bridge though it tells me it cannot find anything that it can connect to. I have dsl (LAC) and a Wifi adapter Usb. can anyone help with one or the other?
