Okay, firstly, what a great car. After my total dissapointment with the new 3.5, this comes as a big relief, and makes me wonder even more why that latter car feels so completely strange to me(way to light ffb, way too little feeling). Just did some quick laps and here a few first notes: I installed the car first and drove my first laps at the 3rd party spa track, without having Indy installed, what maybe explains the issue. I drove the road configuration of the car, but the AI drove the oval config, hence being way faster on the straights, but much slower in the corners

. After that I exited the game, installed the Indy, restarted, and took off at this track. Here/now the AI also drove the road-config, like me. So maybe track dependent? havent tested more to find out.
The car itself feels great: perfect ffb for me(t500) and mentioned here in earlier posts, a very nice sensation of speed. What made me wonder though, is the, IMO, very high amount of grip, foremostly at the rear, the front is OK. I could kick the pedal down all the way in 2nd without wheelspin, and even in 1st it was hard to have the back break out once at speed. But, the track was grippy: multiple laps of AI rubber, and maybe the default setup comes with a very long 1st and 2nd gear, havent looked at that further.
I hope that people can elaborate on this so I can read it tomorrow morning

I've got to sleep now.. bummer.
A very pleasant experience! Many, many thanks to ISI!! Have a nice rest guys, you deserved it.
Edit: forgot something

Performance-wise, the track is very good and an absolute beauty. Same can not be said of a full pack of DW12's, althoug just as beautiful, an fps killer here in my system. Please see specs in my profil. Does someone else also experience fps issues with the DW12?
