I'm not referring to occlusion (like when the controllers teleport away, or freeze), but performance and accuracy. How quickly they follow your hands, the samplerate at which they do so, and how closely they match what you are physically doing. This becomes EXTREMELY important at high level play in Beat Saber, as you can need to hit blocks every few frames.
Quest controller tracking is too sluggish and inaccurate for high level beat saber.
Lighthouse is better, but I find it's still not as accurate as the constellation tracking on the CV1.
This is the first time I've felt a set of controllers match what I was able to do with my CV1. (Like terms of precision. Beat Saber scores you by how close to the middle you cut blocks, and the arcs of your slices.)
