I just upgraded to SpectraLayers 12 and uninstalled SL11, but the GPU processing is no longer working. I have it set exactly as I did in SL11 , my AMD 6800XT is selected under “AI Processing Device”, but it still only uses the CPU. Setting it to “Auto” makes no difference either. I’m on Windows 11…

[grafik] Interesting, here too. Although the graphics card is selected, the CPU is being used, AMD Radeon RT 6800 XT (16GB). But when I switch to CPU rendering, the demixing takes twice as long… EDIT: For the unmix vocals, sl12 uses the GPU.

Same problem here with my AMD Radeon 6700XT. And, if rendering is set to “high quality”, the created tracks are emtpy…

Yes, I can confirm this. The High profile is broken. Fast and Balanced still work, but they don’t use the GPU and are painfully slow. Interestingly, unmixing just the vocals does trigger the GPU, for whatever reason, but the result is just an empty track, so that’s useless too. I’m rolling back to…

Bug confirmed here. Not at my music PC but on vacation now: on my Asus ROG Z13 notebook I had only tested with CPU so far, and conversions took around 5-8 minutes depending on songs. Now I tried GPU (which is VRAM on this Notebook), which took ~4 minutes for conversion of a 7 minutes CPU conversi…

I have the black screen “only” in unmix song in high settings: [image] Song unmix black screen SL 12 SpectraLayers Hi, after installing SL12, no layers are displayed after the unmixed song, either in standalone mode or as ARA in Cubase 14 (current version). The entire di…

I really wonder how issues this obvious weren’t caught during testing. Just a week ago they were promoting SL12 all over social media with no hint of GPU problems, black screens, or any of this. Yet the moment the update goes live, we see all these reports of major problems, affecting AMD, Radeon, I…

The issue refers to GPU cards such as AMD Radeon RT 6800 XT based. Using for example Nvidia GPUs are working for that case. We are currently searching for a solution.

See here: [image] SpectraLayers Pro 12: GPU selected for AI Processing, but CPU still doing most of the work? SpectraLayers 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 G…

This report here refers to the issue that AMD bases GPUs currently not correctly working on High Quality Profile Unmixing while other GPUs such as Nvidia RTX do work on that case. But there are also some improvements to come.

SL12 not using the GPU at all (Win11 Pro, RX 6800XT)
