Here are the upcoming results. I used only Superposition with different modes.
720p 4x => 8x 16696 => 16498 (in this mode, GPU usage is ~65%... so not so relevant i would say) 1080p extreme 4x => 8x 4110 => 4255 4k optimized 4x => 8x => overclocked 2% gpu / 1025 ram 6070 => 6377 => 6791 If we compare with this page of results. Using a filter with vega64, the top user with default clocks makes 6575 pts with a better cpu than mine https://benchmark.unigine.com/results/rid_0fe88b22f59a457797ecbe66d7efccb0 -- Deldycke Quentin On 31 October 2017 at 15:08, Quentin Deldycke <quentindeldy...@gmail.com> wrote: > Hello, > > Some news for people who could be interested. > > Vega 64 works (nearly) perfectly on vfio! > > 1 thing to keep in mind, the vega have a 'funny' pcie system which look > like this: > > - bridge > \- bridge > |- GPU > |- Sound card > > Using acs patch, forwarding only GPU on kernel 4.13, it works. > > I did not test sound card as i have a separate pcie one for the VM > I did not test on native linux to switch between host and vm, but i have > few hopes > I did tested suspend mode of the vm (then i suspend the host).
