Some people move so fast when they play the VR game Beat Saber, a rhythm game that’s basically Dance Dance Revolution with lightsabers, that Valve developers have had to issue a fix. People were moving so fast that Steam VR couldn’t track their movements, as spotted by Kotaku.

After collecting the data on Beat Saber experts, Valve developers had to issue a fix to the trackers in Valve’s Lighthouse technology that tracks movement. On the latest changelog for Steam VR today, developers noted that they had to “Increase limits of what we thought was humanly possible for controller motion.”

A developer elaborated further in the comments that “a properly motivated human using a light enough controller could go faster (3600 degrees/sec!) than we thought.” That’s flicking your wrist a full 180 degrees about twenty times in a single second. In other words, superhumanly fast.

Beat Saber gives users a physical workout while they’re slashing moving blocks of blue and red to the tune of a particular song. And it’s been known as a pretty decent way to get some exercise. But apparently, trying to achieve higher scores on the leaderboard or just for personal satisfaction has motivated some humans to move at breakneck speeds.
