Not F1, but from Flat Trac tests we get don't get pac as such, we get the matrix of Fz, Steer, psi, and camber as inputs, and the corresponding forces and moments. It's up to us to fit the data to a model, Pacejka is typically too slow to use directly in a simulation.
Vi car realtime uses the Pac model and i was sure that could run in realtime (I've never used for realtime DIL Sim though). I was thinking that the downside with pac is going to be the lack of heat data (although I have seen there are some people adding that stuff now in newer models).
But also I wasn't sure if the kind of fit you get with Pac is good enough for F1 tyres, given the details they go to.
I'm not sure what you mean by flat track, but do you have to worry about heat impacts?
