Topic: VDJ Cant Load Math Engine
Since upgrade to 2021 everytime I open VDJ, a message box pops up saying "cant load math engine"

It works, but if I click on calculate stem VDJ crashes

I also don't use the default vdj database location

I think both grafic cards are not supported.
Change mathEngine option to CPU and you shouldn't get the error message while still be able to use the stem feature.

That worked!
Thanks

Is there a list of supported graphic cards anywhere?

Unfortunately not. All we know is that it has to be NVidia, and the GTX 1650 & 1660 are good choices.

My actual djin laptop has a 2070

One of my laptops has a GT720m and is able to use the GPU for stems processing.
So I think the Nvidia 7xx series is the minimum if your 6xx doesn't work.

It would be good to have list of proven "GPU capable" cards/computers - even if we have to do it ourselves.

Where is the option to look up math engine? I'm suffering from the delay in the audio beat and the beat lagging in the visual wave form thing too. Is the math engine changing setting IN virtual DJ Pro? or is it in the PC? Where do I find it?
