Tried it last night and had horrible time. There were some setup things corrupted, the first outing ended up in 10s of 360s trying to get on 2nd gear. Booted the game and loaded a new setup and it started to work a bit better. Didn't like it.. There was nothing that had changed, the performance level was very close to last season with MMG in few laps..
It's just too fast for me. I've never really managed to get any turn on F1 really on the spot, i'm always a little bit too late. Then the error margins.. There simply is no concept of "correct your drivingline". It is what it is when you turned in and that's the decision you have to stick with.
The thing here is... If i switch to T-Cam or Swingman... I'm faster, don't make the same late turn-in.. F3000 cockpit: the same thing. I'm akin to believe it's a viewpoint issue rather than actual car physics or the speeding up of events. Most likely i'd need track IR to drive F1s. Or different camera angle. If i change to different car model and stick MMG physics on it.. It's not such an issue.. The MMG camera is lower and further away than SimBin camera.
Oh, our MMG setups.. Whoah, we went over the edge and far.. Those tank slappers.. way way too soft, unrealistic. Slip angles are overdriven, we get massive turnin and then go massively over slip angle for the most parts of the corners. MMG tyre model has to have pretty wide arc before the slip angle is saturated and grip is lost. That part might be acutally true, i have no idea how those 2007 grooved F1 slicks work in a game that doesn't have grooves, those who know about modding can see MMG tyre tricks of wrong radius/width simulating decreased contact patch and the huge grip that the tiny footprint offers.. not saying i don't like those tires, i do.. but they do allow quite extreme toe-in/camber/caster with extreme soft suspension setup that would break the car midway thru the race.. When returning to more conventional setup, the car starts to behave more like a racer but laptimes drop... Same thing is with F3000, too soft setup is allowed by the game.
TL: DR : MMG is too fast for the netcode, viewpoint is weird and extreme setups making it IMHO not suitable for PrestoGP anymore. Fun to drive if competitive pace is not a target.
