Oh good, the thread turned into an argument over what constitutes a "real" sim.
On another note, more related to the topic:
How do you talk to the engineer? using the regular ps4 headset? I have tried talking and nothing happens.
L1 is the pit radio button by default, so hold that while you speak. While it's held, a list of commands will pop up on the right of the screen, which will change depending on situation (race, in-lap, quali, and practice all have different lists). Yeah, you use the standard Sony headset. You can also set your pit engineer's voice to output to your earpiece in the sound options, which I quite liked.
I have no idea how good it is yet because the audio is really quiet through the DS4 compared to all other PS4 games. I hope there is an option to send the audio to the TV.
You can change the Audio output source, and also the individual volumes. I actually found the engine noise to be very quiet, so I put that on 100, with environmental sound on 90, and speech on 100. You can output the Engineer's voice to your main source, and set whether your main source is tv, stereo speakers, or surround, and you can also output the engineer's voice to your ds4 speaker, or your headset. If you output him to the ds4 speaker, remember you can change the volume of that speaker in your PS4's main menu settings. Where you change the brightness of the light bar and all that. You could also output it to your tv if you prefer, and then set the speech volume to 100, and the other volumes lower, and turn your tv up to suit. That'd make the voice much louder than everything else. Hope that helps mate
Edit: One thing I found rather funny is, when I'm talking to the engineer, he understands my commands first try with all but one, which is "full race update". Every time I say "full race update" in my normal Aussie accent, he tells me he didn't catch it, or there's static on the radio. I can try over and over and he won't hear me. The funny bit is, if I say it in an over the top nasal pommy accent (think Murray Walker), he understands right away hahahaha. Of course this sends me into a fit of laughter, and I don't catch what he's telling me. Thankfully he understands "engineer repeat" in my accent lol.
Also, hidden commands that work any time but aren't in the lists are:
Engineer mute
Engineer talk
Engineer repeat
As far as bugs go, I've also had the one where the box is stuck in second leaving the pits, till the end of the pit lane exit. It's annoying, but not a big deal after playing pcars.
