I’ve just finished a project and was starting to play around with the samples to optimize render times, when i noticed only half my image was being rendered, even though i split the tiles perfectly so each gpu did half.
when i looked into my blender settings only one gtx 970 showed up, so i updated my drivers, after which none showed up; i restarted my pc, with the same result.
device manager and nvidia both detect 2 cards, but blender isnt detecting anything.
