Hi All: I have a Macbook 2.0 GHz Intel Core 2 Duo, running 10.5.8. 2 GB of RAM. About the most processor-intensive thing I do on my Macbook is play a couple of games -- Plants v. Zombies or Zuma Deluxe. (Don't judge! ) Often when I am playing, the games start to stutter and freeze, the cursor freezes every few seconds too. This generally happens when there's a lot of images being displayed in the game, though not always. Usually it will have been playing fine for a while, then the freezing starts. I have tried shutting down all open programs when this happens, which generally makes little difference. Once, I played with the Activity Monitor bars activated. During the times that the computer freezes or stutters, it looks like 100 percent of my processing power is going to the game. (The bars are all the way to the top.) I was just wondering if this has happened to anyone else, and if it's a sign of something actually wrong with my computer, or just an indication that the games are taxing the system. Thanks in advance for any help you can lend.
