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 Pro with the latest drivers and updates, exactly the same setup that worked fine in SL11. This happens with every module, standalone, ARA, DAW, etc. I checked Task Manager while unmixing a song and confirmed that only the CPU is being used; the GPU stays idle except for a few tiny spikes. In SL11, the GPU was used instantly and fully, as expected.
Now, the same song that would take seconds to unmix in SL11 takes multiple minutes in SL12. Please fix this, GPU acceleration is a key part of my workflow. Thanks.
Yes, I did reboot after installing it, I forgot to mention that earlier, sorry. I remember reading somewhere that it’s recommended for SpectraLayers updates, so I make a point of rebooting every time.
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…
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 conversion song, but delivered only empty tracks.
This GPU bug needs a quick fix as soon as possible.
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, Intel, and Nvidia alike.
These aren’t minor bugs, they’re core features (GPU acceleration and the High profile separation) that are completely broken. I’m tired of paying to test unfinished software and seeing this become the norm. I hope they get a proper fix out soon.
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.
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.
Just to clarify, in case it helps the devs, here are all my notes before I uninstalled SL12. There are two separate issues:
The GPU isn’t being used in certain modules or combinations.
Unmix Song produces empty tracks (black screen) in specific cases. (Examples below)
Unmix Song
Default preset
Fast & Balanced: CPU (SLOW) | Result: Unmix successful
High: CPU (SLOW) | Result: empty tracks (black screen)
All preset
Fast & Balanced: CPU (SLOW) | Result: Unmix successful
High: CPU (SLOW) | Result: empty tracks (black screen)
Vocals Only preset
Fast & Balanced: CPU (SLOW) | Result: Unmix successful
High: GPU (FAST) Result: empty tracks (black screen)
Drums Only
Fast/Balanced/High: CPU (SLOW) | Result: Unmix successful
Vocals & Drums
Fast & Balanced: CPU (SLOW) | Result: Unmix successful
High: CPU (SLOW) | Result: empty tracks (black screen)
Drums & Bass
Fast/Balanced/High: CPU (SLOW) | Result: Unmix successful
The only scenario where I could get the GPU to activate was when Vocals was the only selected layer using the High profile, but that just resulted in empty tracks.
Every other layer combination that included Vocals with the High profile also produced empty tracks, but used the CPU instead of the GPU.
Combinations of non-vocal layers (like the drums & bass example above) did unmix successfully with all Quality profiles, but only used the CPU. This is clearly not working as intended.
Another Bug using the GPU with the Unmix Soundtrack function at the maximum quality. Once finished the unmix process, i just mute the vocals and i press play to hear the music and the effects. If i select my NVIDIA 4070TI as AI Processing Device i can hear the leakage of the voices in the other two layers in play. The quality of result is not good. If i select the CPU as AI Processing Device i don’t hear any leakage in play and the final result is really good. I’m on Windows 11 Pro 64 bit 23H2
