https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290997 Jonathan Vasquez <jon@xyinn.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jon@xyinn.org --- Comment #8 from Jonathan Vasquez <jon@xyinn.org> --- For the record, I've been using GPU passthrough for a few months now and it's been pretty solid over all. There are some qwirks but once it's running, it's stable and I haven't had any crashes. My bhyve gaming VM just keeps running :). I've documented this at the below link and have uploaded multiple videos on my youtube channel showing the performance: and Corvin is right regarding lack of resizable bar support. That was the main culprit of what prevented my card from being used. Once I turned it off it worked. Although I believe I'm bottlenecked atm due to it but I can still play Cyberpunk 2077 at 40 fps with maximum settings (the card can handle more so it's not a card limitation), and it goes up to 80 fps with frame generation enabled.
