I'm running on Windows 7x64 Ultimate SP1, Ryzen7 2700, 32gb ram, RTX2080ti and a 1080ti as a secondary card, both 11gb models. So far the only issue I've run into is OptiX fails to render. Something I'm wondering about though, Poser11 would use both my 1080ti and 2080ti together, but 12 lists both cards separately and there is no option to use both at the same time. Any idea why this might be?
