As I am a simple and boring man and more or less do all my races with GT3:s at Imola. I immediately notice if the ai has changed in behaviour from one update to the next. If I notice some percieved changes to the ai I start a race and do the first few sectors and then start over again and again to confirm my findings. And as you say Tamburello is a very good corner to evaluate the ai in terms of how aware it is of the player as well as of other ai cars. And up to this update it was very civiliced (but still challenging) and rarely run into you or other ai. Of course every now and then some car spun as is also happening in real racing but that was more uncommon. Now it seems like it's more or less every time. Another corner that I use to evaluate the ai is Tosa. Like a year ago or so if you tried to pass the ai on the inside they would almost every time ignore that you were there and steer into you but the recent updates cured that and it seemed like the ai awareness had improved a lot. But now it's back to being worse in this regard. And as you say it feels more erratic - overdriving which results in a lot of spinning and causing yellow flags in each and every corner. But as the developers found a good formula for ai behaviour before I have faith in them sorting this out so I can have as good racing as before. And I really appreciate your responding to this so I as a user know that there are real issues and not something I just imagine and that it's being worked on. Thumbs up!
