    >Vulkan would be nice. It doesn't have to be better than that. MorphOS on x64 wouldn't make less sense just because it had nothing better.

    As good would be a good trick.
    We've discussed Vulkan before,and I mentioned Mark's comment about wanting kiero's help on any upgrade from MiniGL.

    At the least, we're going to need an updated OpenGL.

    In any case, I'm not suggesting that a full rebuild of MorphOS PPC should bedone, I'd like to see it, but I understand the impracticality.

    But, as you've said, this is the last PowerMac G5, I don't see the point in not supporting it.

    That's TinyGL for the blue ones :-)

    Wow, I really made a mistake there, eh?
    Funny, when I think of TinyGL I think of the more restricted projects that preceded the MorphOS developers' adoption of that name.

    Out of curiosity, what API does everyone think would be best for improving 3D support.
    A more up to date, fuller featured implementation of OpenGL, Vulkan, something else?

    One thing, MorphOS doesn't run fans full speed on G5 PCIe. It runs fans more or less middle speed.

    Yes, I wasted some of Mark's time confirming that yesterday.
    I should have just waited until someone volunteered that.

    I don't want to eat up his time.

    So, what do you think about PowerMac11 support?
    To me it seems like low hanging fruit.

    Of course you can ask zukow what he thinks about PowerMac11 support but in the end it is not up to him if it ever gets supported in a public release ... :)

    You can even say that it seems like a low hanging fruit but this won't make the support in a public MorphOS release more likely, either.

    Support simply is not ready for prime time yet for various reasons and it is yet uncertain if it ever will be.

    X5000/P50x0 support is a completely different story, Mark and I were pretty aware that it wouldn't vastly increase the MorphOS userbase when we started to add support for it.

    Yes, we discussed it before it was a commitment.
    I understand that it provides us a platform that is available new, and that the point wasn't about the # of new registrations.

    When has this ever been about income?

    But the PowerMac 11 is close to supported already, and many more users could afford this then could budget in an X5000/X0.

    Further,if we're overdue for an ISA switch how many are going to commit to purchasing an X5000 that aren't already OS4 users?

    The last two major adoptions (SAM460, X5000) seem geared toward that community, so how about the rest of us that were already here?

    We've been following the adoption and support of Apple PPC hardware, and we don't get our hardware for free.
    That definitely limits the number of us that are going to make the X5000 upgrade.
    That and the knowledge that a Quad G5 can probably top an X5000's performance.
    And the fact its the last, and still the most powerful PPC system aimed at the desktop market.

    Frankly, if I'm going to spend as much as an X5000 costs, I'd rather spend the extra $200 or so that a basic Power 9 system would entail. But that won't receive support.

    All that not adopting the PowerMac 11 really does is produce a dampening effect on the community. so that people slowly leave rather than wait for the performance boost an X64 shift should provide.

    Sure, you can dictate where the OS is going, but once you're down to a handful of us and the remaining developers, will you all see the point in going to the trouble to continue further?

    I don't think we are making an unreasonable request.
    That,or you can keep running this like a private club and continue to further alienate the community at large.

    Edit: Apparently I was wrong about PPC emulation via QEMU, someone has corrected me and it apparently might be up to the task.
    Also, an X64 platform is probably the better choice for concurrently running Windows, MacOS, or Linux via VM (no QEMU emulation of the cpu required).

    That being said, I'd still argue that 11,2 support (and possibly Power 9 support) make sense as a final MorphOS PPC development.

    But as cyfm has pointed out, its not my choice.

    Then again, wherever the developers lead us, I'm sure that if they have the resources to produce it the end result will be spectacular.

    Maybe Apple's last...

    Perhaps I should has specified last mass produced PPC system intended for the desktop market.
    And still likely the most powerful, mass produced or otherwise, intended for the desktop market.

    Or better still, the only thing we could purchase for the price of a Tabor board that would outperform an X5000.
