Will a 32 bit controller make an average player better than a 16 bit controller? No. Is it more precise. Yes. Overkill? Yes.
A player with a 32 bit controller has an advantage over a player using a 16 bit controller. A 32 bit controller offers an accuracy, precision and a range of motion advantage over someone with a 16 bit controller.
When I swapped out by 16 bit CH Pro Pedals for the 32 bit VKB T-Rudder Mk IV, I was blown away by how much more precise and accurate I was in my rudder movements, which translated to being able to make my nose low turns tighter.
Again, make no mistake about it, a player with 32 bit controllers is at an advantage over someone using 16 bit controllers.
There are some videos posted on this forum by Blade that shows the differences between 16 bit controllers and 32 bit controllers, showing how much more precise the 32 bit controllers are.
