Poor OpenGL performance, but only when keyboard is plugged in (mesa)

I'm having a strange issue when playing the Metro Redux native games (2033 and Last Light).

The performance has always been very bad but I just attributed it to a combination of poor optimization on the dev's part and recent hardware (running a 6700XT using mesa-git), however I recently realized that if the keyboard is not plugged in, my FPS jumps from 40-60 to a more reasonable 160. I obviously can't do much without the keyboard, but has this occurred to anybody else?

If anybody has any idea what could be causing this and where to start looking to troubleshoot it, I' really appreciate it, as I'm honestly at a complete loss as to what could be causing this. Below is the output of glxinfo -B, I'm running KDE using linux-zen kernel.

EDIT: So I've now narrowed it down to the keyboard, my Anne Pro 2. Using another keyboard does not result in the same problems. Tested with multiple USB cables. If anybody has any idea how to troubleshoot advice would be great, but in the meanwhile the solution is to not use the Anne Pro 2.

https://www.annepro.net/products/anne-pro-2 is the keyboard ?

Some things to look into :
Does disabling bluetooth make a difference ?

Have you tried different USB ports ?
