Just come over to PC all of you!
you talking about this or the Ryu jumping vid?
That’s not input delay. That’s processing delay. this happens because the architecture for both systems is different. Both operate at difference frequencies and on different machine cycles for each command. Normally this isn’t a problem when you code at low level languages like binary or assembler, but the higher the language the harder it is to fine tune timing. Combine this with whatever engine the devs used to code the game and you get inherent differences between the 2 systems. On top of that the architecture for the ps3 (supposedly) is pretty notorious for being difficult for devs to work with. This is probably as close as they can get without rewriting a significant part of the code.
