I'm reaching out to other Mac Sierra users with SkyMaxx Pro 3.x No matter what preset rendering settings I try to use on X-Plane 10.5.1rc, SkyMaxx Pro claims have have zero video RAM available. I am using the beta Gizmo plugin, so at least I can use the product. I have a 2GB video card and using 1920x1080 along with the very lowest XP rendering settings I'm constantly getting SMP warning that I have zero video RAM available. Does anyone know if there is an official known issue list published? This would sure save hours of searching forums looking for answers. Maybe I missed finding the minimum hardware/OS requirements too. Thanks to anyone out in the forum that has a few tips.
