I would like to know: Can an RX Vega 64 do compute based rendering using system memory through its HBCC?
GPU Rendering, when done through compute APIs, has te limitation, unless the software allows to do what´s called “out of core rendering”, that the 3d scene needs to fit in the videocard´s memory.
There is a Blender test scene which runs out of memory on 8GB regular videocards like my 390x or a 1080 that can be downloaded from the Blender´s official page:
It´s the Production Benchmark from the Goosberry open movie project.
To test it it´s needed to rise the HBCC shared memory segment, enable OpenCL/GPU compute in the Blender´s user/system preferences, set the renderer to GPU mode and hit render.
Is there someone with an RX Vega who can test this and tell me if it can do the render??
-EDIT: THIS IS MAYBE NOT AN APPROPIATE TEST FOR BLENDER CYCLES / HBCC USAGE BECAUSE MY LAST TEST ON A R9 390X HAS RENDERED THE SCENE -
