I haven't used it but the latest update was four days ago. https://render.otoy.com/forum/viewtopic.php?f=129&t=72278 I only checked a few places (a Vulkan preview announcement, official FAQ, etc) but everything pointed to it only supporting NVIDIA. While I was searching though I came across mention that they've added support for Blender 2.8 which I thought was neat timing considering the discussion we've had in that other thread. https://render.otoy.com/forum/viewtopic.php?f=7&t=72241
Not trying to be a **** but FYI your logo breaks unitys TOS surrounding their branding, and sort of implies you are linked to or affiliated with unity in an official capacity which as far as I can tell your not?
