I haven't played 6 yet myself. I'm going based on a few hours worth of livestreams from the night before release, and the fairly consistent mentions in the written reviews, as well as comments from other players. Are you saying you didn't encounter any tearing or framerate problems on tracks like Bathurst? I saw it myself, and saw the players in those streams comment on the same thing. I mean, if you're somehow right, that's good news. It's just so at odds with so many other voices and my own eyes.
i am saying play the game and tell me it runs worse - it doesnt, it looks better, runs better. most people complaining are watching youtube videos of replays or glitches.
I only played 10hrs and no screen tearing that i saw... In GT5 it was much easier to see screen tearing, for instance race in London, you would get screen tear every time you end lap - this was 720p bumper cam. Or Trial Mountain, last corner where everyone bumps together.
Now if you try to look for problems, i am sure you will be able to find some... I entered replay by mistake and it was laughable buggy crap that you see on youtube - it looked low res, glitchy AA and bad framerate when i entered cockpit. But this is not gameplay.
Gameplay i raced in London, no screen tearing, much nicer standards and much better track overall with better textures and lighting. Much better suspension and driving feel as well... much faster to get into the races, prettier menus, etc, etc.
I am not really sensitive to frame rate, and I didnt mind occasional screen tear in GT5, it didnt really bug me, i put hundreds of hours if not more in that game and Prologue.
When I remember flickering shadows of GT5 that were everywhere, and standards that looked like someone stuck decals on a cardboard box, it is really funny to read how GT6 runs worse. Well it does not. And if some cockpit view on some race does drop a frame or two at 1080p and you are annoyed by it, drop the darn game to 720p. It is not magic, next gen consoles dont run PS3/360 ports at 60fps.
