Hi Allesio, I've added you to the whitelisted developers. I'll let Jim address your suggestion of adding Direct3D to the OpenGL/Vulkan forum when he gets back tomorrow.
Cheers and welcome back!
PS - you can now post in any of the Developer Forum forums without moderation except the "Newcomers start here." Even though you are whitelisted, that forum always requires moderation.
Thanks for your patience Alessio. Just FYI, the reason we set things up this way is.... we need to approve you once, and then your posts do not require moderation at all, ever. I whitelisted most regular users in advance, if I missed you, my apologies.
