Okay...they've definitely reduced the tearing when the wipers are on...and by quite some margin. Not completely eradicated, but they've definitely reduced it by a ton.
If you used to take the Esprit and put the wipers on, the tearing was a disgrace. Now it's negligible.
Now while there is still some shocking omissions...seriously, if GT5 had have been as it is now at launch, it would have been so much better. The most frustrating part is could have been. It's just too bad that probably 4/5th of the audience have long since left and their impression of GT5 was a bad one.
Loading is better, you can buy parts wherever you are, tearing has been reduced, confirmation prompts have been cut down, no more having to press X to go back, the game is now rich with online seasonal events.
It's just too bad. If I was Sony I'd be kicking myself that I didn't give PD a bit more time; though I guess on the other hand, without community feedback, there's no guarantee that PD would have implemented some of the stuff they have.
