I feel like every fighting game that is released on ps3 and 360 always has rumors about a 1 frame delay told to me by someone who owns the console without the delay. Honestly, i play so many damn fighting games across pc, 360, and ps3 and i cant tell a difference. Using the same fightstick across all three systems (two in the case of doa5) and the same 2ms evo standard monitor, i never see a input delay. Now, i would say that they all three feel different somehow but i never feel like i can say without a shadow of a doubt that one system has a frame delay over another in any case.
Can someone tell me, for a fact, that the ps3 version has a 1 frame delay on input? Your sure that your tv isn't just shitty? or that your stick isn't just shitty? you didn't go over to your friends house and play his ps3 version with his sticky controller on his old ass 720p 20ms tv?
And as far as graphics go, its marginally different between 360 and ps3. If i only owned it for one system i would buy it for whatever console doesn't break as often......
