does hugin>nona support cuda? my UHD630 is quicker at this moment

[Maarten Verberne]

Hi,
I've been using command line to stitch a batch of 2 images.
and have use of a nvidea card.
however when hugin uses the gpu with -g in the command i see it is not
using cuda shaders at all but calculates in the D3D memory.

as a result the 160 or so shaders on my intel UHD630 do actually perform
quicker in that nona action.

now, i dont mind using the uhd630, but if i can use the cuda card i'd
sure like to know ;)

I'm curious, too. My Dell laptop has both UHD630 and Nvidia 1650MQ. It uses the UHD no problem, don't know how to make it use Nvidia.

Nona is using OpenGL shaders to do the calculations. It does not use CUDA nor Direct3D.

So using a more powerful graphic card should speed up the remapping stage.

Sounds like in theory it should work like that, real world results for
me however are different.

the build in intel uhd630 outperforms a much quicker dedicated GPU by 50%
....and with less power usage.
