Every so often, a new term sneaks into controller specs that makes even controller collectors like me pause and squint. The latest buzzword is TMR, short for Tunneling Magnetoresistance. It might sound like something salvaged from the Roswell crash, but it’s actually a new magnetic sensing technology used in controller sticks, and many brands are starting to use it.
You’ve probably only just gotten familiar with Hall Effect joysticks and their promise of ending stick drift, now along comes TMR, touted as the next step forward in precision. So what exactly is it, how does it differ from Hall Effect, and do you really need it in your controller?
