I recently installed Win 7 on a 90GB partition on my macmini. Below are the specs of my macmini. 2.3Ghz Intel i5 RAM 4GB (i upgraded it from 2GB) *i think this model was released in 2011 or 2010. The latest update, with thunderbolt. I installed MW3 on steam, but i lag terribly. it failed when i try to play campaign. i havent even started playing, it keeps on crashing after playing the plot videos. Are there any way i can optimize my macmini or is the problem originate from the software (game). Please help!
