I am having problems playing the online game Runescape on my new Dell. When I move character with mouse, the walking movements arent smooth. It will stop and start, like its thinking what to do, and then the character will be like in a running mode. This happens all the time, and it is very frustrating.I am not sure if this is a Java issue, my graphics card, or what. I also am connected to the cable internet through a wireless card. Maybe that is the problem?? Anyway, my old computer works great, and it is more directly connected to cable box. Any suggestions out there?? Other than this issue, the computer seems to be fine.
