FreeBSD offers a whole bunch of technologies and tools to make gaming on the platform a lot more capable than you’d think, and this article by Pertho dives into the details. Running all your games inside a FreeBSD Jail with Wine installed into it is pretty neat.
Initially, I thought this was going to be a pretty difficult and require a lot of trial and error but I was surprised at how easy it was to get this all working. I was really happy to get some of my favorite games working in a FreeBSD Jail, and having ZFS snapshots around was a great way to test things in case I needed to backtrack.

No, this isn’t as easy as gaming on Linux has become, and it certainly requires a ton more work and knowledge than just installing a major Linux distribution and Steam, but for those of us who prefer a more traditional UNIX-like experience, this is a great option.

Agree with ‘no’, even with Ubuntu Linux latest distribution I wasn’t able running StarCraft II without bugs & using PortProton.
Maybe in future if Windows/NVidia/AMD won’t prevail, that will become a good option, but for now the answer is still ‘no’.
It seems almost laughable that FreeBSD gaming is stuggling so hard, given the PS3, Ps4 and PS5 are all built upon FreeBSD.
All of those use the FreeBSD kernel while replacing everything on top with a custom, fully controlled stack though, moreso since it’s all hardware that they fully control the drivers for. That’s a very different challenge from trying to make the very Linux-specific WINE work on a typical FBSD userland.
