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 m= ain 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 p= lay 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.
