In the advertisements, Radeon ProRender boasts that it is fast. But in Blender’s Viewport (Rendered) it is not very responsive. It is slower than Cycles, and it randomly becomes black.
In my case, the CPU is faster than the GPU and it seems that using GPU makes Blender’s UI stutter, so I use CPU rendering. When using Cycles, if I set a sample like 4~16 for the Viewport, dragging the Viewport is rather smooth. I mean, right after I started dragging the image is jaggy, but Blender’s UI itself responds smoothly. When using ProRender, even if I set the lowest sample count, which seems to be 16, it is still not as responsive as Cycles. Also, when selecting an object, 1 out of 3 times, some part of the Viewport becomes black.
Does this happen to most users, or is this because my CPU is slow?
