Been a long while since last posted in this thread. I am just resetting my garage/favs. I admit I stopped playing GT7 for a while, close to a few days after 1.49 because I don't know, kinda got frustrated, burnt out maybe? Anyways, started playing GTA 5 (which I have because of my son but never got to play it before) finished the main story game, then came back to GT7 now with 1.52.
So, what I've decided to do is to just reset my favs; clear them all and start anew again, this time tuning for the new physics. My Favs now are all cars tuned for 1.52 onwards until next physics change. So that's what I've been doing these past days including today. Grab a car, test, tune, go to the Nordschleife paddock for testing with traffic, tune; change cars, rinse and repeat.
