Hello, i have three GPU on my board, but natron use only my GTX 750, i want use my GTX 780 (where my screen was pluged) How i can change that ?
Please go to the NVIDIA control panel and change the entry in "Preferred graphics processor". In my case the less powerful intel chip could be replaced with my mobile quadro card. However, I only have one NVIDIA card. No idea if all of your cards will show up.
Hope this helps.
