    <div class="moz-cite-prefix">Hello Okky,<br>
      <br>
      To be honest, I don't play any games at the time. But I'd say Tomb
      Raider and Bioshock Infinite if I were to play something else. Or
      maybe Crysis 3.<br>
      <br>
      I guess our hosts are very similar, as I have an ASRock Z77
      extreme4 and the i7 3770.<br>
      I've just installed linux-vfio-lts 4.1.12, too. It actually fixed
      some crashes of my host whenever I was shutting down the guest.<br>
      <br>
      I've tried without pinning the CPU, and use your topology, and I
      got a tiny boost in GPU performance, but significant lower CPU
      performance (about -20%) all tested with passmark.<br>
      <br>
      I'll try Unigiene Valley benchmark tonight I think. Thanks for the
      suggestion.<br>
      <br>

                                                    provided about 2%
