We have some game with telemetry, which shows how grip changes at every tire and a lot of other different stuff in real time. From the other side we have game which shows nothing.
GT5 Prologue.
Prologue, as in, introduction. Demo. Gran Turismo 4 had full telemetry data.
Games are different, which one you will trust?
Take into account all this strange things in GT5P, like when you change aerodynamics and adjust down force from min to max, your top speed doesn't change at all. It doesn't make GT5P more believable.
And just where can you do full speed in GT5P? There are no tracks which will let you reach the top speed of many of the cars in-game... and, personally... adjusting aero in the Gran Turismo series has
always caused a change in top speed where the top speed wasn't gear-limited.
No. With most of simulators you can almost double your speed with ideal racing line.
"Double" is an exaggeration. You can eke out that extra tenth of a second that no one else has found, but that's it.
In real life, you can have an entire field of drivers separated by just one or two seconds on a track taking wildly differing lines. There's no magic line that allows you to pull more than two or three seconds a lap in a field of somewhat competent drivers. Against racers? A perfect line won't be worth a second a lap.
In Prologue the difference is much smaller. Probably because sliding cars don't loose too much speed, they continue moving forward and moving sidewards at the same time. All that you need to do is staying somewhere inside the turn.
I know we've had this argument before... but again... in pro mode, you can get
nowhere near the top Time Trial times by doing this in GT5P.
You can gain something by opening the exit, but it still far from what the difference it makes in other sims
The difference between driving a picture perfect lap in GT5P and driving a loosey-goosey one is worth several car-lengths in Time Trial, at least. I've ghost-raced dozens of best times and when the other guy is driving the perfect line, I struggle to keep in touch when doing four-wheel drifts... in
Professional mode. In Standard mode, sliding is the fastest way around the track... but nobody plays standard mode.
All the standard mode junkies are playing Shift, now...
You can make all the claims you want about the poor communication of grip-limits in GT5P... as that's a personal thing, and I agree, somewhat... but your claim that driving a perfect racing line makes no difference in laptimes is outright false, given the evidence of the online leaderboards... which anyone can view and download at their pleasure. And that aero doesn't change top speed? Given you don't have a huge test track or Sarthe circuit in GT5P, how do you know? The only cars that can hit their top speed on Daytona are the lower powered ones... and even then... increased aero can still increase your speed on Daytona, up to a point, as it gives you more speed off the banking.
