Hi there, I am currently checking the gfx-api's for mac and the games that support it or were patched to use them.
I am only interested in intel igp, not any dedicated gfx-cards.

< 10.11 32/64 OpenGL
> 10.11 32/64 OpenGL + Metal (1)
> 10.13 32/64 Metal (2) + OpenGL
> 10.14 32/64 Metal (2)
> 10.15 64 Metal (2)

Is this correct?

So talking about 10.11+ we are talking about intel HD-Series starting from HD3000.
HD3000 is opengl only, metal support is from HD4000 and above.

For a retro gamer like me, does the metal api, especial from the beginning in macos 10.11+
have any advantages, or should I stick to openGL?

I could not find any overview or comparison with games that got metal support via patch.

Feral did some metal-patches to games like Tombraider 2013 and Batman ArcamCity.
But these were perhaps Metal (2) patches that require 10.14+. I don't know why they did
not made them work on 10.13...but that could most likely be due to the macmini 2011
that has HD3000 and this had no metal-support.

Would be nice to get more information about that toppic...

Greetings
Doc

What games were ported to metal (1) and run from 10.11+ on intel gpu?

Each macOS version added many new features to Metal, even if there was no new big marketing number after it.

OpenGL is supported on every macOS version, even macOS on ARM will support it.

Did someone a test on intel gpu with opengl vs. metal on the same machine? i did!

Tombraider 2013 on MacMini (2012) i5 Dualcore 4GB 2,5Ghz @ 1024x768 Medium, Textures High

Benchmark on 10.14:
- 28fps OpenGL
- 23fps Metal

hmm... that's bad!

Actually I was thinking about my gaming Mini (2014 i7 3Ghz 16GB Ram Iris 1,5GB) that is actually on 10.11, but some games force me to install 10.12, some want me to install 10.13 (DeusEx-MKD), and some force me to install 10.14...

I think I can forget METAL on that machine because it will perhaps give me no advantage. So what about OpenGL ? Since 10.11 is OpenGL 4.1, are there newer drivers, better optimisations for my iris gpu? I do not have read anything about that.

Any suggestions?
