To be brief. I'm rendering relatively small scenes (mostly crystal structures) in blender, and I recently got an RTX 2060. Interestingly, when I use the default settings (with auto-tile size) Blender 2.79 indicates that my GPU has 12 threads. This results in noticeably worse performance as shown below:
12 Threads = 2:59.02
1 Thread = 0:56.30
Does anyone know why this is the case? Is it a case of hardware misidentification? The difference is pretty significant.
