Problem there old bean is GT7 seems to operate on the strict notion that 0.5% too much throttle is insta-death.
Same goes for braking 14% brakes isn't enough to stop you... 15% brakes unsettles the car and is insta-death.
I get everyone who isn't having issues is big burly hairy chested men, but at the end it the day this is a game, it's supposed to be fun and accessible. Maybe PD could introduce an adjustment menu to increase the tolerances for smooth driving and insta-death.
Now true there's assists in game TCS, stability etc but all these do is numb the sensations, they essentially remove the reasons your playing Gran Turismo and not say Need for Speed.
I've had to run with full assists on (bar auto drives) and the cars are lifeless and on the replays they look silly, constantly twitching and bobbing and wobbling as the game tries to kill me and save me all at the same moment.
For this game to survive and keep players here both new and old like myself it needs to chill on the hard-core surgical precision thing, because frankly after a hard day at work last thing I want to do is have a second job trying to play a game.
Because as I said... its a game at the end of the day.
