So after playing LOTRO for a good 3+ hours, I noticed the memory usage for it on Norton was around 2,000,000kb, whereas upon launching the game it's at 1,100,000kb, and can reach 1,600,000kb. Is playing the game for extended periods of time normal for having the memory increase? My computer's pretty high end, with 12gb of RAM, so it can handle it, I assume?
