This has been like 10 years in the making it seems ever since Nvidia was booted off the mac platform!
So now until apple catches up with nvidia say M4/M5 or M6 era.. then we can ditch the PC too maybe..
But for now.. best of both worlds… working on mac using the power of the RTX 4090 or multiple if your that lucky.. up to 10 render nodes with multiple RTX cards is possible… OH… also best part..this is also fully used when doing IPR functions as well so we have a network rendering accelerated IPR for Lookdev too!…. Combine this with my Stream-deck XL (Look for the shortcut templates over at https://www.sideshowfx.net/products)
They have them pre done for cinema 4d as well as many other apps!
Add to this my 3d spacemouse for navigation.. It is absolutely wonderful being fully on mac with no compromise!
