Vive wireless performance 40% worse than wired

[4GD]

Sorry in advnace if this isn't the right place to be posting.

I recently noticed that perofrmance while using wireless with my vive pro was significantly worse than when using wired. Seemed to roughly be 20-30% worse, which somewhat agreed with what I could find in other posts/forums (although disagreed with what I had understood from Vive's marketing).

I have come across OpenVR Benchmark which seems to be a pretty good way to get consistent results. In doing so I get around 40-45% worse fps when using wireless. Wired at ~49fps compared to wireless at ~28fps.

Is this normal/expected?

 

Hardware: 2080 ti, i9 9900k, asus z390-e, vive pro.
