I never played a GT game with a wheel up until 2014. Had a lot of fun with most of them, but GT6 I even platinumed and 100%ed the Senna DLC. I signed up for the closed beta earlier this year within 3 minutes of the sign-up site being up and got in.
GT6 ran on a system without the processing power to run a physics simulation à la rFactor - which always seemed like a fair excuse to me. Now on PS4 Project CARS(yes even 1, it was not a great sim, the physics were off more often than not, but it simulated so much more than a GT or Forza) and especially Assetto Corsa showed that the cheap console CPU is capable of running sim physics, there is no excuse for GT to not step up the tire model and other parts of the simulation.
With the lower car count, I was hoping they'd actually modeled the suspensions, to feel bumps affecting the FFB and cornering behavior correctly, but no.
This is the game for me that PD decided that GT is not the best simulator on console, but just a competitor in the Forza -style market, going for the same amount of realism and not an inch more (though, it drives a bit less **** /more forgiving/less annoying beyond the adhesive part of tire grip than Forza 5-7).
But is GTS fun?
Yes and no. It's fun when you can drive like an idiot on the Nordschleife and get away with it because with a lower wheel-lock degree of rotation, you can always catch the car. It's annoying when you brake(a tiny bit) and steer to get better turn-in response and ...then you understeer and overshoot the apex because the braking is stable no matter the brake balance because it's made for a controller. It's annoying when you have to go 100% clutch travel to shift into a new gear (it's a clutch "button" not axis), it's annoying when you down-shift 2 gears in one go without rev-matching and the rear does nothing unusual, and also when you try to correct the cornering radius in a FWD car with lift-off oversteer and there is hardly any of it.
Then there are no FOV options(GT used to have this in the games before, hidden in the multi-monitor options) no option to turn off the onscreen wheel, sound inside the cockpit and lighting exposure setting are really bad...
No, I can't support this thing. I tried with feedback during the beta to improve it, made threads explaining ReelFeel FFB, explaining the importance of FOV, pointing out brake balance, bump- and off-track grip problems that will be bad for eSports. Nothing. Best thing the devs changed was "seat position options" - but no FOV.
