Well my CPU has 8 P-cores, 16 with HT and then 8 E-cores so I'm always going to do better with the P cores. The boost is different on the P cores as well and I'm using DDR5 memory which is also better from what I've heard with P cores. > By any chance have you run a VirtualBox VM?

I was actually planning on doing this in the next few days Wine isn't cutting it for a few programs. I use emulators/libc6-shim/ to turn CUDA on for my FreeBSD apps and another one for Linux you could try that it's been amazing to have CUDA on FreeBSD. > I'm getting tired of trailblazing!

Wait until you get to the sound issues. I haven't had time to dig real deep into what's going on with that but it's starting to get really annoying as well. I'm sure this all has the same root problem. Amar.
