In system prefs the CUDA tab shows my card GeForce RTX 2080 SUPER. I've selected this option, and de-selected my CPU (3900x). I then select via the inspector tab the Scene options, then under

Render Engine : Cycles Feature Set : Supported Device : GPU Compute

I then render the scene, the CPU is being used first (can see via task manager), and the GPU goes to about 8% per png image rendered. Switch to CPU not GPU and the the CPU goes up to 90% and GPU still uses 8%. It takes the same amount of time to generate an image ~30 seconds.

What is the expected speed up for a 7.5 rated CUDA card, with > 3000 cores on it ? Does anyone else have any stats when using CUDA with Super 2080 please ?

I'm using

Blender 2.8 Windows 10 CUDA 11 NVidia Driver : 451.48

I've noticed the fastest rendering settings are Cycles, Supported, GPU Compute - but setting the OptiX in the system settings - with this each PNG renders in around 20 seconds.
