When using the Unmix Song feature on ‘High’ setting (in the standalone application), and when selecting any layer that requires a lot of VRAM (‘Vocals’ seems to require a lot more than ‘Drums’), my 3070Ti 8GB graphics card seems to max out on VRAM and SpectraLayers immediately crashes. It did manage one run where it got to 4% processing before crashing, but 99% of the time it just crashes before processing any audio.
It works on ‘Balanced’ or ‘Fast’ as it doesn’t seem to use as much VRAM.
Is this new algorithm being limited by the fact I only have a graphics card with 8GB VRAM, and is it worth me finding one with much more, say 16GB? Or is it potentially a bug in the program?
Cheers, Jim.

I checked the ‘Documents \ Steinberg \ Crash Dumps’ folder and all I see is a ton of Cubase crash dumps but nothing else. I think it’s crashing too quickly to do a dump.
Aye. I’ll have to use the CPU for a while. Got a 285K so it’s fairly ok. Not the slowest. About 10 minutes to unmix a 3 min piece of audio. Does the job while I go make a coffee, or a 2-3 hour walk if I’m doing a large project. Time outside is nice.
Thanks for reporting. Quite hard to know what goes wrong here; most GPUs seem to handle it fine, but some GPU+driver+OS combinations seem to have a harder time handling the VRAM load.
The VRAM load is supposed to be managed by the OS+driver, when models are bigger than the VRAM capacities the OS/driver is supposed to switch back and forth between RAM and VRAM automatically, that’s not something controlled by SL.
That being said, to mitigate the problem when the OS/driver seem to have issues handling it, I could add another parameter to balance the CPU/GPU load, prioritizing slower models on the GPU, and leaving faster models on the CPU, so the memory load would be more balanced, while still keeping reasonable computation time.
Thanks Robin. I’m a bit of a newb when it comes to computer programming and how hardware works, but I think I get what you mean. That would be cool if you could implement something like that.
I’ll try a driver update for my 3070Ti to see if that helps in any way.
I have a 1050, so no GPU for me so far. That said, my unmix timings are something like yours, I guess…I haven’t tried to unmix music longer than 7 min so far…and my recent tests of 5-6min rock band type material takes about 10-15min per. And that is no big deal because, like you, I can do something else…laundry, various little chores, feed some animals, pick fruit, watch some streaming, play music…lots to do!
