RX5700XT not working in viewport render; final render works

Question asked by Guest on Mar 19, 2020

Dear forum,

 

I'm using Blender 2.82 and RPR 2.3.4 on MacOS Catalina with a Mac Pro 2013 and an RX 5700 XT eGPU.

So far everything seems to work fine except RPR being not as stable inside Blender as Cycles Renderer for example. But if you don't rush in your workflow and give RPR time to breathe there's little to no crashes.

 

However my issue is the following. I want to render using my RX 5700 XT. As mentioned this works fine with the final render. However the viewport render does not render at all with this card. I tried

 

  • under "render devices" checking the "RX 5700 XT" --> NOT WORKING
  • + checking "separate viewport & preview devices" and checking "RX 5700 XT" --> NOT WORKING

 

However it works with the internal GPUs

 

    • checking "separate viewport & preview devices" and checking "FirePro D500" und unchecking "RX 5700 XT" --> WORKING

 

So it seems that RPR can't handle the RX 5700 XT in preview render.

Is this a known issue and is there a workaround for this?

Besides this RPR just seems to be working fine.

 

 

Thank you for your time and best regards,

Jonas
