No. It doesn't. There are other games out there, racing games even, that are capable of holding 60fps.
GT has a lot of graphically challenging conditions in it, but those are a design choice. PD chose to sacrifice graphical stability for eye candy.
Some people prefer that. That's fine. But you can't claim that GT has a great frame rate, even compared to other games, because it just doesn't.
Remember that he said "console games"...now tell me racing games on consoles apart from Forza 4 or Gran Turismo 5 that runs nearly at 1080p with steady or close to 60FPS.
I´ll reply for you saying that "NONE" of them. All racing games and almost every other game on CONSOLES runs at 30FPS, all NFS from Most Wanted to Shift, Motor Storm, Nascar The Game, etc...Games are locked at 30FPS and if we talk about multi-platform the games looks horrible and perform as bad as they look, on PC you can max out any of them and have double the frames.
The number of games that runs at 60FPS are counted with the fingers of one hand on consoles...CoD for example (all of them count as one), Forza, GT, and maybe some 2D platformers which are not so graphically demanding?
So having in mind that, if you say that PD "sacrificed graphical stability for eye candy"...it shows that they made a great job having in mind that most of the other games can´t do that.
And compared to other games having in mind how the game is structured and that still there are people comparing GT5 graphics with newer games such as pCARS and Assetto Corsa (that looks quite impressive, I own both), I think they made a remarkable job.
There are a lot of CPU demanding stuff in the game such as day/night/weather cycles, the car physics even if they are not perfect, a lot of variables in the tyres (temperatures, when it gets dirt, etc), AI´s, when you have the car with damage ON and something breaks...etc. We got and we´ll get too much having in mind the hardware of the PS3.
They also probably tried to go way too far "for the eye candy"...yet they managed to achieve the goal...even with its flaws.
And for the last bit that you said about GT not having better frame rate compared to other games...for me it has better frame rates...above 30´s is always better.
The truth is that PD needs more power...PS4 hopefully will be the answer...hope they won´t go too far again because if you know something about PC hardware...the APU is not that powerful...they need to balance things up starting from simulation, game-play, features and graphics/sound.
I expect photorealism coming from them without a doubt at 60FPS 1920x1080p, but I will also love to see a 24 car starting grid at least, day/night/weather in all tracks, better physics and new content not recycled from the PS2 era.
Let´s see what happens...by now I´ll enjoy GT6 if the frame rate issues of the cockpit view from GT Academy were addressed.
