Supposedly the result of the the Atomiswave's Netplay function using too much memory, there are several issues in the game caused by hardware lag. The first and most critical is that there is in fact a slight delay in switching guard from high to low or low to high. As a result of this, certain characters air dash overheads can be extremely hard to guard. This is even more so the case for the two 'tall' characters, Raoh and Mr. Heart - in some cases it can actually be impossible for them to guard a low air dash move on reaction, making it necessary to stand before the opponent starts to perform the overhead. Another issue is the stage lag that occurs while performing certain moves(Supers, Guard Cancels, anything involving Boost) on some stages, the most common being Shin's stage and the left side of Toki's stage. This lag can easily mess up the timing of your combo, so it is important to keep in mind when lag is likely to occur and prepare for it when playing on these stages.
