Cyberpunk 2077 comes with tons of technical and performance issues on PlayStation 4 and Xbox One, but it seems like there is an unconventional way to improve performance while traversing the streets of Night City.

Reddit user joshmaaaaaaans discovered that by shooting at any time during the city in a crowded area to make NPCs cower or run, then look away from the scene and back again at it makes most of them disappear, improving frame rate in the process.
