and what do you guys thing about RR compared to Assetto? ....I have some car/tracks but last time i tested i thought it was a bit inferior...do you think that has changed, really? D

If you're asking "has something changed in the last months?" then the answer is defenetely yes: all the most recently released and most recently reworked cars have an updated tire model (the most noticeable thing is the adjustable tire pressure, but more has been done to it, at least that's what I feel from the game) and the old cars that got updated also got some general physics tweaks...
Now, if you ask my personal opinion as some sort of R3E fan, that for some reasons was never able to enjoy AC but really likes how cars drive in ACC (when it runs), just to give you a couple of references, I can tell you that I like these new "creatures" from Sector3 so much, that I almost cannot enjoy cars running on old physics and old tires anymore... and that sadly (still) includes all the most popular cars in the game: GTR3, all DTM cars, all Touring cars...
Good thing is you don't need to trust me: the Formula Raceroom Junior was made free for all at the end of last year, and in that occasion received the latest physics and tire model updates, so that is a quite good preview about how new cars in R3E feel... other old cars that have already been updated (and you might happen to own) are the GTR2 and the Cayman Trophy from the current SRS season, and the 911 GT3 Cup from the previous one... I might be forgetting some, but those are the cars I personally recently checked... and if during the summer sale you want to get something new, then the GTR4, Group C and the Carrera Cup from the current and last seasons are all great cars... also the brand new Formula 90 should be awesome, especially if you like that era of F1 (I still haven't tried that, but I'm most likely going to get it with this sale)
Another cool feature recently added is that during the free Test Drive, you can now adjust the setup (before you could run only the default setup) so you can really get a complete idea of what you're going to buy and how is it going to perform with different values... pretty useful when deciding wich car of a new class you should get (if you got limited budget) or to try by yourself if some of the cars I mentioned fit your likings...

Thank you by your sincere and detailed answer and RR review.

May be i should try it again , sometimes i see some RR combos on SRS that are interesting!
