OK, I understand, 3Drendero. I'm wondering, though, for the Mac side, since Open GL and Open CL are deprecated, and the Mac OS does not come with the latest versions of these open standards -- I'm wondering if, during compiling, it would be possible to include the latest versions of Open CL and Open GL, and get the Mac OS to use them, at least when Reality and Lux are being employed. Is that possible? I don't know. But it was a mistake, I thing, for Paolo, in essence, to neglect the Mac OS, and go with "Windows Only" in his ads, when he had been promising a great speed boost to both the Mac and the PC users. I know he lost some of the Mac people at that point. And he himself had been writing on the Mac, I believe. Anyway, that's the past, and we can't send time travelers back, as in Travelers or Continuum, so looking to the future, is it possible to get the Mac OS (Catalina, especially, the latest OS), to use the latest versions of OPEN GL and OPEN CL when the user starts up Reality and then Lux? I'd be as happy as Kiera to travel into this new future timeline.
