I haven't played games in a very long time. After getting my 2ghz intel iMac with 1gig ram and ati 1600 256 meg vid card i figured games like: halo command and conquer battlefield 1942 call of duty medal of honor would play smoothly! maybe it's my settings but these games are laggin!! Is it because they are not optimized for intel or do i have my settings too high? i set them to "high/max" in almost everything aspect and to almost the best if not the second best resolution... ideas?
