hey mate did you ever get around to making a video on the wx range, on rx and vega video you pretty much say their pitiful. Being that the WX are workstation card it might be a case of horses for courses. ( hell i would happy asd the wx cards are much cheaper than P2000!!! there a head to head video for you…WX 3100/4100 vs P2000…can hear boxing ring bell ringing lol)
anyone wondering about the performance of a AMD workstation card (radeon pro WX3100 specifically) here is a another plex user experience
Hi,
Yes, sure. I really like to give you information. 
I use it mainly for Video playback, so to speak video decoding. Working great, ranging from 576i to 4K, from mpeg2 to HEVC all is working pretty nicely. But no VP9!, 4K HDR@60p is kinda hard, it does play it back smoothly but you shouldn´t do anything in the background, otherwise, you will see many dropped frames in your performance stats. The Linux support is also not ideal. Video decoding yes, audio passthrough nope
The WX 3100 on the server side is a completely different topic, unfortunately…
I’ve tested it with Ubuntu 16.04 (i think it was 16.04…), no hardware transcoding, but I imagine if you spend some time looking for a solution, you will find it.
On the Windows (10) side of things, it is working great… But not many transcoded streams,
I´ve tested it with 1080p@h.264 content which worked fine and with (odd) 3840x1080p@HEVC files. (3D full side by side) which worked partly well…
1080p: I was only getting 4-5 streams
3840x1080p: nah, only 2 or 3, I think,
Not very good results in general… Unfortunately 
But I think it is AMD related, as it nearly the same like in the video ->
Hardware Transcoding with AMD GPUs in PLEX
All that is the reason, why I will probably sell it.
If you have some questions, ask me!

I’m using the keylase/nvidia-patch and it works well on Ubuntu server.
The only problem with Nvidia cards under Linux is the lack of hw-decoding support in Plex.
I loaded up 8 transcodes of h264 1080p 20Mbps --> h264 1080p 12Mbps.
I had trouble getting more clients/tabs playing because of CPU decoding (+DTS-HD audio decoding - AAC encoding) for my rather weak CPU. But at this stage I had the NVENC hovering around 30%.
It’s like it was mocking me - Is that all you got?
Anyway, GTX1050Ti is a cheap man’s P2000.

Managed to get myself a cheap p4000 which I know is massively overkill for my use case. My issue is I use unraid and then a plex docker for the server. And unfortunately nvidia drivers have not been built into unraid and AFAIK there is no immediate plans for this to happen.
I’m now thinking of making a vm(win 10 or Linux??) to run plex but I’m concerned I don’t have the resources to give the vm and run the dockers I have atm. I know this isn’t really the forum for that. But I guess my question is what’s the minimum cpu and ram allowance I should give the vm to get the most from my p4000. I have a 4790s and 16gb ram. I was thinking of maybe 2 cores and ht core for 4 logical cores and then 4 or 8 gb of ram???
Also I seen someone mention that their server will only encode the files and not decode or vice versa… Is this a likely issue to be concerned with??
nVidia GPU transcoding is still not an option on FreeBSD, right?
Linux AND FreeBSD. Yes it will only decode so you need Windows to fully use it.
Bummer. Well that’s useless. I don’t use Windows in my home.
Yeah same here I first wanted to switch to Windows but I like BSD/ZFS over hardware transcoding so I bought a p2000 but send it back instead 
Does anyone here know how to force Plex to use the P2000?
It keeps using the build in IGPU no matter what I do?
I have made the P2000 my primary display in the bios.
windows or linux ?
pretty sure the only way is to make sure the IGPU is disabled and drivers removed.
I am running in a Docker for Plex on UnRaid (They just released a Nvidia plugin to allow direct access to your GPU from any docker) Only problem is that for some reason it keeps selecting the IGPU - So yes Linux on docker
Plex doesn’t support decoding on Nvidia GPU’s… You may need to use this ‘hack’ to force it to.

So I have been out of pocket for a bit due to work and am playing catch-up. I am seeing the news that 4K HDR transcoding now supports tonemapping on the fly. Does this work with the P2000 or iGPU only?
EDIT: Well, it must not work on iGPU because I am not seeing any tonemapping going on. Still a washed out mess on my son’s SDR TV. This is running build 1.15.0.659.
Certainly not working on the P2000 either. Pretty sure its not a thing yet.
if you want to keep the iGFX enabled you can just use nvidia control panel to select plex to use the gpu and that way you can keep using both graphics chips on your OS but force plex to use the quadro.
I’ve tried this and I’m not sure I did it correctly. I went to the manage 3d settings in the nvidia control panel, added plex and selected the quadro. Then I started transcoding a movie to test it and the igpu and cpu spiked. So I disabled the igpu and tried it again and the p2000 spikes to like 30% and the cpu to around 40%. From what I read about this card, it should barely be moving with one transcode. It’s installed in a Dell Poweredge t30 and windows 10. I had it running on linux and had the same issue. There isn’t anywhere in bios that I can find to disable the igpu, only make nvidia the primary and I’m not sure how to disable drivers in linux. Any help would be greatly appreciated. I’m pretty new to all of this.
