Hello!
after nearly 5 years of passing through my Radeon HD7800 - it feels old and
slow when used with newer games and 1GB of RAM also doesn't feel right
anymore...
I tried a VEGA 64 - i was able to live with the ACS patch needed here (Z170
Chipset... not needed with the old HD7800, but whatever...) - but i couldn't
stand the reset/FLR/Bug which forces you at least to suspend/resume the host
when you want to reboot only the guest...
So my question is - AMD or NVIDIA, i dont care, cheap or superexpensive (ok,
not the quadros) - what do you recommend these days for a hassle-free
passthrough experienence (well at least mostly - acs patch needed would be
ok, reset bug not so... it just makes it unhandy to use in day-to-day
scenarios...)
Wouldn't needing the ACS patch depend on your mobo as opposed to your GPU?
I thought so, too! But then this: For my old HD7850 i do NOT need ACS
patch, to get it working flawlessly in my Z170 Board - it works with a
debian standard kernel even;
The Vega 64 - in the same slot, same board - needs the ACS patch...
dont ask me why... i can only guess it might have to do with the pci
bridges "within" the Vega64... but thats not more than a very uneducated
guess....
Greetings!
fwiw I have had a flawless experience passing through a GTX1080 with multiple
dynamic rebinding events.
Thanks very much!
