Pressing multiple keys simultaneously, or holding one key down and pressing another causes a massive input delay, or no input at all on the second keystroke. This only happens in the build and not in the editor. I have vSync turned off and Process on Dynamic Update turned on. I can’t figure out why this is only happening in my build. Any advice would be appreciated.
So an update - my bug was specific to a midi hardware implementation and not the unity input system.
Keyboards can only process 3 simultaneous key presses at once. might not apply to all of them, but on a typical usb keyboard this is a hardware limitation and not a Unity issue.
