[Rizzaz]

 

Just looking for some idiot checking before embarking on the idea as it aint cheap

 

I have a Dell server with x58 chipset (16xpcie 2) dual 3Ghz 550 Xennons, 24Gb of ram on SSD cache running unraid 

 

looking to VM a mchine for HTC VIVE so would need to passthrough a 1070 ?

also need to power the 1070 so sepparate 500W PSU should do it?

Do you think this would work before i drop £1250 k on it??!?

VR being so extremely sensitive to frame times I would say a VM is a very bad idea, VM for standard gaming is sub-optimal so I have very slim hopes of it being playable consistently. Since you have all the other parts already and if you'll use the 1070 anyway it won't hurt to try but don't do this if it's your one option and it's sink or swim.

that is a very ghetto solution for a very expensive and sensitive product

With passthrough, I seem to get withing 10% of the host performance, with no noticable difference in performance.

 

My main issue with gaming vm's is the pain to do anything, like add a usb drive. They also seem to have more issues with crashing. My vm doesn't let me download gpu drivers and install them, I have to wait for windows update to do its thing.

Yea performance is there but what concerns me is the consistency of the frame times, something not really that noticeable if your averaging a decent frame rate in a standard game but in VR you'll really see it.

The cpus are below minimum spec for the vive.

 

Also if those pcie risers if they are cheap there have been people who have broken gpus with them because they are soldered poorly. Check them before you actually use them.

this all sounds like a no then, especially if the CPU is under spec...  i hadn't realised  that,

 

Oh well, thanks for the replies!  

 

I guess you could get around the VM part by instead having a second drive you swap in for the purpose of running VIVE only,even that the CPU's are slow aren't they, but with a fast cpu Maybe?  I just don't need a full Gaming tower, but I do use the server, so could upgrade it...
