I have recently changed the levels of some of the ai drivers and the tier characteristics but when I'm playing the game its like nothing has changed. Do I need to do something to the game first to make it recognise any changes i make? I have started a new career and deleted my save files but still nothing is different regarding the performance changes I have made. Help
