FreeBSD would work well for your purposes, it has a really good hypervisor and linux abi compatibility

I doubt it.

I am a diehard FreeBSD fan and I used it on my laptop for 20+ years, and dualbooted it for windows only for gaming.

I tried my best to get gaming going, even running Arch in a jail, but it's not great for gaming purposes. I was even virtualizing OpenBSD to use PCI passthrough for better wifi...

Today I am using Arch Linux instead of my dual boot setup. Is it perfect? Nope, but at least I can play Age of Empires 2.

I still use FreeBSD on my servers, obviously. FreeBSD is great, but on the desktop, and especially on the laptop, there are some warts.
