Topic: Stems 2.0 are terribly slow on an RTX 3050 laptop
As the title says, the new stems are terribly slow even on hardware that is supposed to support real time stems separation. A 2 minutes file takes like 5 minutes to be fully analyzed when placed in the Stems folder, despite my GPU reporting ~100% 3D and dedicated memory usage in Task Manager.

I have already tried the "Don't use GPU" option and I have already verified that I am running the latest NVIDIA drivers.

This has been covered several times now but the RTX3050Ti with 4gb VRAM does not support stems. It will be reverting back to CPU therefore causing the long loading times.

Atomix need to let people know this as I highlighted the issue on a brand new laptop several weeks ago.

Should've done some reading on the forums prior to posting that. But still, Atomix has lied to us...

They have said they're looking in to a fix but nothing as yet. The issue was only discovered after the stems 2.0 release.

ASUS zenbook UX8402za windows 11 22h2 home 12th gen i9-12900h 2.50 Ghz 32 gb RAM, nvidia geforce RTX 3050ti. VDJ2023 b7388. Rane ONE ASIO 1.0.1 .

several optimization settings , different ASIO latency settings, and windows power settings.
STEMS 2.0 works fine , VDJ works fine, and no processor or RAM spikes. GPU on NVidia will run 95% on stems precompute for one minute depending on mp3 file size.
but i can do several hours of no glitches, then just erratic audio latency static.

i continue to receive random audio cracks distortion static.

has anyone reinstalled windows 10 ? over a preinstalled windows 11 ASUS laptop.

would this be a viable option to try?

Check the latency. Nvidia video drivers cause bad latency when driven hard. That's why I returned my Zenbook.

No such issues here, on desktop or laptop.

Maybe just an Asus thing but major issues with nvlddmkm.sys and it's well documented too.

thanks, i'm going to have to switch to AMD with ASUS.
meanwhile continue to search for a settings fix.

i can't seem to get around the dpc latency problem with ASUS board and the NVIDIA 3050ti i will do a few more test with no stems computing, because STEMS will run the NVIDIA 3d gpu up to 95% and 98% for one minute.

i was waiting for maybe an updated driver from RANE, or NVIDIA, or Microsoft that will help the glitch.

both of my windows 10 lappys work without a problem.
