Topic: Suddenly Real Time Separation Performance Issues?
Hi,
I'm using VDJ since 2 yrs on my laptop, always used live stems separation, which was usually done in 20s per song.

Today I discovered that VDJ always takes very long for each track, and even reports:

Has there been any changes lately in the algorithm, that could cause this issue?
I'm on
AMD Ryzen 7 5800H with Radeon Graphics 3.20 GHz, and NVIDIA GeForce RTX 3060
16GB RAM
2.1Ghz GPU
7GHz VRAM

"StemsGPU" setting is automatic, but I can only see approx 10% usage of the GPU while separation. Even if I force using the GPU with this setting.

Stem Speed shows about "1.2" during calculation.

WTF:
StemsFix was on "Don't use GPU".

How could that come suddenly, 100% sure I did not change that myself...
 
Maybe the GPU was being used for something else when you booted VDJ at one point and it swapped over due to a lack of vram or something.
 
Oh, I see. So VDJ maybe deactivated the GPU usage for some reason, driver issue or similar.

But can I prevent VDJ of doing so? Because, the setting was now the default and it took me hours to spot that (even installed several downgraded versions).
When I have a gig, I would rather VDJ to warn me about that and let me decide myself if I'd want to rather close VDJ and fix the VRAM problem before running it with silently deactivated GPU usage. That's very bad.
 
I'm sure there is warning that does come up to say the Gpu is not available and it's reverting.
 
Could it maybe be just a "Windows Popup" that automatically hides after some time (means: launching VDJ and returning to the notebook after 2 mins may be missing this message if not watching the screen constantly?)
