Hi there everyone, I am in need of some help from some Mac Pros. I got a new iMac last year in September, and I put Vista on it near the end of December. I found it was working great. I installed a few games on it, and they seemed fine at the time. Now after using the games a few times it seems they are slowing down a bit and getting choppy. Are there any updates or anything i need to install to fix this? Please and Thank You for any help I can receive.
