What version of CUDA are you working with? my version it's 10.1, perhaps if I dowgrade, it will work?
It worked with 115px but nothing bigger so it's strange.
I managed to make it work with 500px, it seems that graphics memory is the issue, so i had to restart the machine, kill all the processes and just leave Dainapp open then process the 500px file, I couldnt go any higher than 500px.
Is it possible to process image sequences with alpha (like png)? maybe in the future?
