@Nagra - They use OpenGL for compatibility reasons. I remember in one of those weekly 'Blender Today' livestreams, some discussion to that effect. They mentioned Vulcan as a future option if I recall, but OpenGL was chosen for compatibility. Thr standard cannot "die", because it's open software. The Blender Foundation are free to make use of it for as long as they wish, there is no entity that can take it away, and newer cards need to be backwards compatible with it anyway, so OpenGL will always be valid for any option that requires it.

@Clarkie - Sure, and no problem with what they did. I was just curious how they did it. I wasn't aware Cycles has been given a different licence. Unfortunately though, it does mean that Poser won't be getting EEVEE, which is a serious bummer IMHO. The stuff it would have permitted to happen would have really boosted Poser in the credibility steaks I think. Their only options now (if they wanted a realtime viewport), is to either develop their own realtime PBR renderer, or licence one. But if they licence one then the chances of Poser being used as a free attraction to content purchasers, looks extremely unlikely.

See, thing is, if they had their own motion generation, and it was better than the competition, they could make extra cash through selling an "Export Motion" option. If they had a model like that, it means they attract content purchasers through Poser being free, and those purchasers have to stay inside Poser unless the pay extra for the Export Motion option. That way, the business model thrives on content, but also the sale of the Export ability. They get to do both while being able to pull people in through Poser being free. But without a realtime viewport, the realtime rendering and motion generation features that attract people, are just a dream.

@Wolf - Wouldn't make any difference mate, cause who cares what version you're on? Once you switch to Linux, all that keeping-up with the Joneses bull becomes a thing of the past. And even if you wanted to upgrade something without breaking something from an older install, you just run it right there, in a Virtual Box running Linux on Linux!

You're completely safe from all that worry once you break the umbilical cord with your dictator

Listen to what Ton is getting at in the video attached, cause it applies to the OS situation too, not just Blender. He points out that we won, and we won because we're now up there with the big, rich, and powerful. The "we" who won, are every one of us with the sense to see where this is going, and who understands why it is unstoppable.

So what he's telling you is that with "our" new found power, "they" (the giants about to fall) are getting worried, so much so they're now wanting "us" to join "them". Ton has basically told them, no, we're the winners here so it's time you joined us in our way of doing things. He is absolutely spot-on, and the same is true for Linux-based OS users, they are the winners of the OS situation for the very same reason ...

Reason being the power of Open Source, and the business of freedom that will always be preferred by every person on earth!
