Optimal NVIDIA control pannel settings for Spectralayers?

What are the best NVIDIA Control Panel settings for the spectralayers app?
Just leave it as is, or tweak certain settings to something else than defaults?

(Image just for context)

I recently upgraded my “old” daw with a newer GPU, but honestly I’m not impressed by the outcome in terms of spectralayers performance. I still see a lot of CPU load, yes the GPU does take a load, but it is not maxing out mem and not much else seem to do much..

Edit - these are my SL settings and the song length above is about 4 mins.

In SpectraLayers, check in Preferences, under “System | Miscellaneous | AI Processing Device”, that you have selected the GPU.

All good there :wink:

Not sure what’s happening in your screenshot, but the estimated time is ~6m … how long is the piece?

The song is about 4 minutes

I have the same card and it will run “Unmix Song” on a 4m piece in about 4m, so roughly realtime, and it will show quite a bit of activity on both GPU and CPU. Bear in mind that not all of the AI models used for separation will run on the GPU, so the amount of activity will vary during the process and of course it will also depend on the nature of the source material (and more specifically, on how close your source material resembles the material used to train each model, something we as users do not know).

That said, there is definitely something in your setup that is resulting in the GPU apparently not being used at all.

To get back to your original question, I don’t have any non-default settings in the “NVIDIA Control Panel”, in fact I always just do a clean installation of the Studio driver. If you go to “Help | System information” and click “Save”, it will generate a text file for you with all the relevant information which you can upload here for comparison, however I suggest you remove the system name and Device ID as I have done below:

Here are my settings, looks very much the same, however my CPU clock is probably lower, which is probably the main reason for the differences we see.

I tried enabling “Shared Mem” in the SL prefs, and that actually loaded ALL gpu mem fully - initially it looked good with a better time estimate, but then SL crashed :grimacing:

About the app specific settings in the NIVIDA panel - I’m also running with defaults, but there are a lot things to tweak, which is why I am curious. I do miss some more options in the SL prefs for GPU/CPU settings.

Apart from the slight difference in driver version (I didn’t install the latest one because I saw nothing relevant to audio usage in the release notes), one thing I notice is:

The fact that enabling “Shared Memory” in SL resulted in more GPU RAM being used (good) but then crashed (very bad) might suggest some issue with data transfers between system RAM and GPU RAM. Since SL12, a full “Unmix Song” seems to require 18-20GB, so it seems to be trying to do that, but there is still almost no activity on “GPU - 3D”.

For comparison, here’s screenshot from my system from about half-way through “Unmix Song”, with “Shared Memory” enabled:

Perhaps “Resizable BAR” can be enabled in your BIOS? (link for Intel systems)

The disabled Resizable BAR is a very good candidate for the differences we see.

Enabling it on my old Asus X99-A II board has turned out to be nearly impossible. ASUS have not made any official BIOS updates that enables resizable bar. Yes, there are unofficial patches and methods, and I’ve tried them (e.g. this one [Report] ASUS X99 Deluxe II Resizable Bar Mod and updates - #16 by gonzo - Reports: BIOS Modding Results - Win-Raid Forum ).. but I keep ending up in the same dead end where I can’t set the rebarstate. I even tried booting directly into a simple UEFI grub console and set the rebarstate variable directly, which goes through, but in effect doesn’t change anything. Mighty frustrating!

I guess my best hope with this HW is that the developers fix the shared mem bug and whatever the issue is that causes the GPU not to be used as it should.

Mmmm … resizable BAR should at best affect only performance though, and it’s absence should not prevent using the GPU compute, and certainly should not trigger a crash.

I have since updated the driver, the updated system information is below, for reference:

One other test that might be worth trying is to run the Unmix Song modules individually, to see if perhaps only one of them causes the crash. Not all modules use GPU. That might not necessarily tell us anything useful, but at least it could make it more usable for you as a temporary workaround.

Just a final thought: have you tested your system memory? I mean thoroughly, for example, using memtest86+ ?
