Meanwhile other users say that “the entire game is lagging” and that there are serious framerate drops as well, with Rock Band 4 going as high as 60 FPS (frames per second) only to drop back down to 20 FPS and it’s “very noticeable.”

Rock Band 4 players are also reporting problems with the game’s accessories as well. Earlier this week, the game’s co-publisher Mad Catz did apologize for the lack of Rock Band 4 instruments and legacy adapters available, but on top of that, it seems that those who have been lucky enough to get their hands on the instrument bundles are experiencing problems too. Destructoid editor Patrick Hancock reveals that the guitar bundle he bought didn’t include a copy of the game, while the publication reports that another users actually ended up with PS4 instruments in their Xbox One bundle.

On top of this, input issues have been reported with the game’s drumkit and microphone. The microphone apparently has some vocal lag for some Rock Band 4 players, while the drumkit has hit detection trouble that’s so severe that one user had to come up with a makeshift fix – folding a paper towel into a rectangle and sticking it where the magnet meets the sensor.

In terms of official fixes, Mad Catz has apparently released several firmware updates for the instruments but unfortunately, in order to get those firmware updates, players will have to connect their plastic instruments up to a PC using a USB to USB micro cable (Xbox One instruments) or via Bluetooth-enabled PC (PS4 instruments) but a USB to USB micro cable isn’t included in the box and not every PC has Bluetooth, so it leaves many players unable to access the solution.

While it’s disheartening to see Rock Band 4 join a growing list of games that have launched in unfit states over the past 18 months (Tony Hawk’s Pro Skater 5 being another recent example), some are also concerned that this will see Harmonix lose sales to Guitar Hero Live, which launches later this month.

It’s also worth considering how this will impact the newly rebooted music rhythm genre overall. Hopefully Harmonix will be looking to fix things and make it up to the Rock Band fanbase soon, so Game Rant will update on any new developments.
