I've noticed when I've been playing the Sims 2 recently that a message has been appearing asking me to close the game to lower my RAM usage. This is when I have 6gb of memory and only the game open, no internet browser or anything else. When I check my RAM usage when I have nothing loaded up, it says that 'Service Host: Local System' is using up 46mb and Windows Antimalware Service Executable is taking up about 40mb, and after that there are a few programmes using around 10mb before it drops down to a few using around 2mb. So there is no majorly obvious problem, yet my usage is still hovering at 79%. Does anybody know what I can do about this? Thanks.
