I just want to test a theory here, nothing sinister at all.
No, no, I see your point. There has to be a reason why some people don't seem to suffer from bugs and others seem to suffer a lot. I latter case I would not be happy either, I understand completely.
Tuning: I have driven most cars in stock version the first 3 seasons. From then on I started tuning them, mostly suspension and brakes. Some of the cars a complete make-over.
Tyres: I use both options, sometimes Automatic by weather, sometimes I choose myself.
Wheel: Thrustmaster T500RS, pedals also, and TH8A shifter (switching from H to SQ depending the car. If the car has paddle shifters, I use them too.
Career: just started season 7 in Ginetta GT4. As far as karting and Formula goes: only invitationals. I did three seasons Clio Cup and then started in GT3 / GT4 / GT5 teams. Did all the endurance races the game threw at me.
Alle races full time practice / qualification / races.
PS4 is from May 2nd, 2015, only use is PCars, no other games.
I disabled penalties for long endurance races (before patch 3) since I got some not deserved DSQ's.
Now I enabled them again. Switch between full damage and only visual.
Started with AI at 60, switched quickly to 70, and last two seasons at 86%
Playing time is between 2 and 6 hours/day.
