@Luboš: thanks for the hint, tested with nvidia 'enterprise' drivers from
12'2019,
acc. to download page they support vulkan 1.1, i couldn't find any settings or
info in the control panel, former drivers have been from 2015, LO 7.0a0+: 

use openGL for all rendering: ~41k rows/20sec, 

no accelerators activated:    ~31k rows/20sec, 

use Skia for all rendering:   ~11k rows/20sec, 

high-res mode, thus skia still with problem, 

didn't test 1920 mode, but was already fast with skia and old drivers, 

unfortunately the driver has degraded the good performance of openGL 

:-(

but it's still usable and much better than skia, 

hope that helps?
