Exclamation [FTC]: NXT control delay

Throughout the season, we've been having issues with a significant delay between gamepad commands and actual robot movements. This varies from ~.25s to ~.5s. We were going to just deal with it, but I realized the emergency stop is useless because of this. The NXT seems to be executing code with little to no delay (we've tested screen output of commands received and it is very responsive). The NXT will enter and exit programs like it should, but the motors and servos do not respond quickly (if we e-stop the bot, the program will end, but the motors will hold their previous state for up to 3 seconds).

I'll gladly provide more information on our setup if it will help solve the lag issue.
