I just bought a mac mini about a half a month ago. I ordered it from apple's website and got 4gb of ram and the 2.66GHz Intel Core 2 Duo processor upgrade. Eventually I installed Windows 7 Ultimate 64 bit version in order to play Guild Wars from time to time. When I play guild wars for the most part, on all the best settings it performs nicely. ~60fps mostly. ... It is just that every once in awhile, its really unpredictable, about every 3 minutes or so on average, I can notice a slight skip or chop in gameplay. The game will freeze for about a half a second or less even, and then resume and play normal. Then it will do it again...and again...and again. At first I thought it was Guild Wars, even though the game is 5 years old and my mac mini is not even 1 year old I still decided to turn down ALL the settings and set the resolution to low. But this problem still occurs. I am not sure if it is as frequent as compared with when I have the recommended settings on, but it still happens. So today I tried to install Warcraft 3 on OSX. The same problem happens. I can run the game with ALL the settings on high, and its smooth, but randomly it will freeze for about a quarter of a second. I cannot seem to replicate the problem either. However it's really noticeable to me and it is getting annoying. I am curious anyone else with the same mac who is playing games on it, do you find something similar to my problem?
