After completing 14 races, - it's good, but buggy. Not sure if it was mentioned - if you use flashback during Quali hot lap, sometimes the timer resets to 0 upon exiting flashback and you end up with a full lap time ~0:35:5, instead of 1:20.x or something. Also, sudden lag is kind of weird. In Monaco going round the Bus Stop fps drops from the usual to about 5 for a few seconds, returns to normal when you enter next corner and hit the tunnel.
Pit stops are inconsistent. A tire change usually takes about 4.2-4.3, which is fine, but sometimes on an absolutely empty pit-lane it takes ~6.8-7.2 seconds without any additional changes, let alone the bug that simply freezes you at '30 angle of your pit box or when mechanics let every1 pass before they release you.
Also took me over 10 races to realize that during interviews you're offered three different responses, the one it offers by default turned out to be the second (middle) one, instead of the first one, which is counter-intuitive.
Curbs also differentiate on the chance of spinning out. All the races up to Monza - fine, in Monza - spinning on every curb in sector one, same goes for Singapore. In Silverstone curb in 3rd to last corner is visuals only, car goes flat over.
