I'm not sure that this is a bug -- at least not in the sense of game play. Since probably 4 - 6 revisions (updates) ago, the game takes far more resources than before. The two processes involved are csrss.exe and TennisElbow.exe. The memory usage is surprisingly low, which is great. The CPU utilization, though, changes frequently, and can be quite high, even when the game is minimized and just waiting at a menu. It just seems that TE2009 was much faster many revisions ago. Is there something simple that can be done to improve this? I don't know -- maybe this feedback will at least let you know that there is this issue. I don't know much about programming, but maybe some change was made somewhere that can be adjusted to make the game "lighter?"
Thanks!
