SpectraLayers Pro 12: GPU selected for AI Processing, but CPU still doing most of the work?

Hello Steinberg team, I’m using SpectraLayers Pro 12 on Windows 11, and I’ve noticed that even when the AI Processing Device is set to GPU, the majority of the actual processing still seems to be handled by the CPU. I monitored the system via Task Manager and observed high CPU usage and very low GPU activity, even during intensive AI-based operations. System specs: CPU: Intel Ultra9 285K RAM: 64GB DDR5 GPU: NVIDIA RTX 5060 Ti OS: Windows 11 While I understand that some minor inconsistencies…

High-end Intel/Nvidia based system.

User didn’t specify the card, but it’s Nvidia:

Song unmix black screen SL 12

If I select Module>Unmix Song, then select (yellow) the Bypass button in the popup dialog, rendering happens instantly to a blank page as per your screenshot. If I “unselect” Bypass (i.e. leave it in the default state), unmixing proceeds normally (no preview). I have processing set to Nvidia GPU.
