Amazing feedback Synwraith. WOW.
What you think about the sounds? Improvements? Or the build is too early to know?
To be honest, because I never got to try it with headphones, a lot of the background noise often masked the clarity of the sound from the demo. I am guessing the build probably is quite early - certainly the build of demo that was on before the last revision ended up being very buggy. We couldn't exit the race screen without it crashing, even restarting in the pause menu meant we had to reset. The frame rate for the demo was noticeably low too, something everyone familiar with GT5 commented on immediately.
I must say, thanks to the amount of time we spent on the Silverstone International circuit, I've grown to absolutely love that layout. The high speed first section is exhilarating and it was a surprise how early you had to brake and turn in to get optimum entry and exit...and goodness help you if you missed your turn in and had to take a second bite at the cherry! It was extremely satisfying to nail the late apexes of some of those tight and twisty mid-section corners. Getting on the power too early did result in some quite merciless snap-oversteer in just about all the cars I spent a significant amount of time in (Countach, Dino, SLS GT3, Nurb GTR, Ford GT, 370Z Academy edition non-tuned).
To give an idea of lap time, the SLS GT3 was capable doing 1'02 at the Silverstone International layout on Racing Hard without aids, the 370Z Academy edition on sports soft was clocking 1'12 - this in the hands of experienced GT wheel drivers.
In the last section of the track, after the chicane, the double right-hander seemed to work well if you got the cars into a very slight drift and just worked the power with a low steering angle. To begin with as I was getting used to the new and sensitive phyisics on the powerful cars I found it easier to almost make multiple small inputs as the smooth fluid approach seemed to be sending me into spins - but with time the latter approach proved faster as you would expect. Both Alex and myself were left wondering whether our first laps were the result of rustiness on our part or a definite shift towards higher sensitivity physics. I think we concluded it was a healthy mix of both.
Something else to add, Alex commented when watching the Academy champions how they were throwing the cars into the corners with super-late braking tactics, and when he was driving against their ghosts he was noticing that while he was quicker on exits in a number of spots, the Academy/real drivers were amazing on the brakes. After he saw how much more beans he could give the car on brakes, he found a lot of lap time. Hopefully Alex can chime in and give some more of his own insight in this area - and I am sure his impressions will be slightly different to my own.
Regarding any comparison with sim-racing PC physics, my only point of reference would by GTR Evo, and I wouldn't say the physics of what I drove in GT6 Demo - for the time I drove it - were more similar to that than GT5, but that's not any sort of detailed comparison so best to wait on that one. There was definitely the whole 'Gran Turismo feel' evident in the demo physics. I do recall that in the high speed left hander of turn 2 at Silverstone I could really sense the roll in the cars at that speed and under high aero load. That was really brilliant, I felt, especially in the SLS AMG GT3.
All the best
