Hi there

Not sure if you are sorted this issues,can you check if this does happen if you do render with CPU? If not I would thought so or I would say is down to TDR,which you need to increase,around 8-10 should be enough,but this more prominent on new Pascal cards which is GTX1060 as well and can you check yours VRAM usage,if you have installed GPU-Z then check there VRAM usage and check this as well in Poser log,this I have saw few times when I rendered very complex scene

Hope this helps

Thanks,Jura
