Hey all, I've done some more testing and improved my post. I pretty much got a full = blown gaming set up working. It has it's qwirks but definitely can play gam= es on this VM now. I no longer use RDP at all. Since passthrough is working= , I just plugged in my monitor directly into the GFX card. Once you start t= he bhyve VM, you will get video out at full power (- w/e performance lose w= e have due to running in a VM). But I'm not getting any lag or stuttering d= ue to RDP/VNC stuff. Since I have a KVM, I was able to pass through my mobo= 's USB stuff to the VM which means the KVM allows me to use my keyboard/mou= se in the VM, and I can even use Ethernet and sound as well since the KVM h= as a headphone jack. So with all of that, I have everything I need to play = games on this VM with the AMD Radeon RX 6900 XT. The nice thing is that thi= ngs are just going to get better on FreeBSD from here :). Please check out = the info on my page again and let me know if anyone has any questions. I'm sure that we will get improvements in the future for: - Resizable BAR support - Fixing any issues with slowness with some games (probably a byproduct of = something else going on) - Any weird graphical/artifact issues in - some - circumstances. Although i= t seems when I do get graphical issues, it's only temporary and doesn't mak= e the game completely unplayable. @Tomek CEDRO I'm not against getting this documentation into the handbook, but from my l= ittle work on getting some documentation updates into the handbook, there a= re specific guidelines that need to be followed with language used, structu= re, etc, and there are a lot of side things that I didn't describe in my do= cument. All of this would probably need to be fully fleshed out and polishe= d before something of this magnitude would be accepted as an official chapt= er or section in the handbook. Although I agree that it's very valuable inf= ormation and a highly sought after use case I would think.. at least it was= for me. I was thinking this technology would be out of reach for me for ma= ny many more years, but I'm happy that the day has finally come, and on my = favorite OS, FreeBSD. Let's go!!
