LRC 15 slow to create AI mask

Hi all, with the last version of LRC, the mask AI creation became slower related to previous version.

I use a gaming laptop with 32GB RA;m Intel 7 10gen, dedicated GPU nVidia RTX2060 with 6GB Ram, SSD 1TB with 2 partition (LRC is installed into second partion with catalog and relative cache)

When i created a landscape mask, depending by photo, LRC take almost 20sec to create the 3-5 masks. the GPU memory is load around 4-5 GB. 

The library works fine; my catalog is around 3000 pictures

The regulating sliders work fine but the mask creation is very problematic.

I already tryed to re-install LRC and check different youtube tutorial

Do you think that my laptop is underated?

Do you have any suggestion?

Thank you

Best regards
