@Tomek - CD Projekt / Red <3. They've done an excellent job with GOG and their ga= mes. I'm all about that DRM Offline Gaming lifestyle lol. - Check out the first remark. Basically I'm passing in both the integrated = and the dedicated card (I disabled the integrated card because I need to pa= ss everything in that Bus if I want to use the mobo's USB/Sound stack which= happens to be on there as well). I then connect my monitors HDMI cable dir= ectly to the dedicated card. So no RDP/VNC. It almost feels like I didn't e= ven have FreeBSD installed lol. when bhyve boots up the monitor receives th= e signal automatically. I'm passing my KVM into the VM through the USB as w= ell so my keyboard/mouse/sound also get passed into the VM. My server is ru= nning headless (I connect over SSH) so it doesn't need any graphics. Howeve= r, the machine does have output from both cards at boot time and early on t= he FreeBSD boot process, it's only once it starts too boot that the video d= river no longer sends anything to the cards and allows those devices to be = passed through later on. So if there was an issue at boot time, I'll still = be able to administer the machine. It's my home server. - These instructions won't work for Intel/NVIDIA because they some differen= t requirements and configuration options from what Corvin mentioned in his = talk. I know some people had to patch the kernel so have some sort of KVM s= ignature implemented or the NVIDIA driver wouldn't work. I'm not sure if th= at's still the case. For AMD none of that was required. It just works assum= ing the system is configured correctly it seems. @Peter I've heard of this before but I don't think will be using it. I'll always b= e physically present around the gaming machine and don't really need the ex= tra software running on it, plus give that I'm directly wired, that would b= e the fastest performance possible given the setup. But I took a look at th= e page and based on the system requirements, I don't see why it wouldnt wor= k ;).
