Hi Nathan, note that it says:
"Radeon ProRender is built on OpenCL™ 1.2, which means it can run on virtually any hardware and will harness the compute capabilities from both GPUs and CPUs!"
on the download page, so I guess it should be updated.
@nathanletwory, please add this essential feature, who wants to render forever ? 
btw. i cannot change the groundplane color, it remains pure white and overexposes the whole scene. Does this work for someone ?

Does the changed gp work ehen toggling the display mode?
No, it’s color cannot be changed, even in RenderedDisplay mode. I can switch the gp On or Off though.Switching to different display modes ignores the assigned color here.

I installed the WIP and was going to download and install a fresh copy, but after I put in my license info I’m sent to a page with this error message:
Server Error
Please visit http://discourse.mcneel.com
The link is working this morning 11/8/2017.
Has just released a new version of the Pro render plugin for Rhino6 Beta.
Yup, that is what @andy wrote a day ago 
Downloaded latest WIP and installed it and the plugin Macuso just posted the link for. Still getting the Error loading message.
The problem is being investigated.
Thanks nathanlewory,
I have another program, Photoscan (beta 1.4), that has issues with this card too (HD 7970).
I’m thinking about going back to one of the earlier drivers to see if that makes a difference.
I removed the NVidia card from the computer to make the testing less complicated.
Let us know what the results are. In our system we could see an AMD driver exception sent in by you, so it very well could be a driver issue.
I rolled back to AMD driver Crimson Relive Edition 17.3.3, as recommend in a discussion related to issues with AMD drivers and Windows 10 Creator. I will let you know how it goes.

Hi @bisenberger, i use HD7970 with crimson relive version 17.2.1 driver and apart from a few bugs with textures it seems to work.

Hi @clement, I’m running a batch process with the 17.3.3 driver that typically makes the card burp. If it doesn’t hold up I’ll try the 17.2.1 driver. Thanks for the heads up!
I tried the 17.3.3 and 17.2.1 drivers and still not working.
Could there be something else causing it to not initialize? an earlier version did work, before I did the uninstall prior to installing the new release.
Here is a link to the instructions I used to uninstall the earlier plugin (in case that could have messed something up):
https://wiki.mcneel.com/rhino/5/rhi/uninstall
Also sometime in the past when I installed an earlier version of the plugin, and it would not load, I checked the box to not load again. Could that cause and issue?
I have also tried installing the plugin for just me and for everyone with the same results.
Hi,
hard to say whats wrong. I’ve looked in the installer file to find out and double check what is installed on my system. I’ve installed this once only, using the “Just me” option btw. In the installer there are these files:
FireRender64.dll (2.538.496 bytes)
glew32.dll (370.176 bytes)
OpenImageIO.dll (7.660.032 bytes)
ProRender.rhp (168.448 bytes)
These have been installed in this location:
C:\Users\UserName\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-ins\ProRender (2aae3eb3-985b-4e64-b19a-fed69ef9dfeb)\2017.11.6.756
Check if you have them and check if the size matches. The RadeonProRenderRhinoPlugin_20171106.rhi file has a size of 3.176.189 Bytes. Could it be you have a bad download ? Did you unblock the rhi file before installing it ? (i did).
Btw. While searching for duplicates of these files on my system i’ve found there is a OpenImageIOv13.dll under C:\ProgramFiles\Rhino WIP. Not sure if that is required at all…

c.
Yes, they are both required, as they are different versions.
Hi clement:
Here is my install folder:
C:\Users\Mark\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-ins\ProRender (2aae3eb3-985b-4e64-b19a-fed69ef9dfeb)\2017.11.6.756
and here are a list of the files:
The file OpenImageIOv13.dll, is located in C:\Program Files\Rhino BETA\System on my system.
hmm… wonder if the beta makes a difference…
BETA
(6.0.17311.8431, 11/7/2017)
Beta
Not sure either. Mine is installed and located here: C:\ProgramFiles\Rhino WIP and i do not have a Rhino BETA under Program Files. Do you still have the folder for the WIP ?
_
c.
Nope, don’t have a WIP folder. I download the full install the other day to do a fresh install of the WIP. I didn’t realize it had been upgraded to a Beta when I downloaded it. When I uninstalled the WIP it must have removed that folder (unless I did it manually after uninstalling (don’t remember)).
It looks like the beta was released on the 7th:
