MP 1,1-5,1 PC 5870 to work with cMP?

I thought that OCLP removed the limitations.

Does this mean that need for Metal is removed from macOS11 -> :

Legacy Non-Metal GPUs and macOS Big Sur - Sequoia · Issue #108 · dortania/OpenCore-Legacy-Patcher

Thanks to recent developments in the community and great work from @ASentientBot and the Moraea team, we've made great progress on GPU Acceleration support. GPU Acceleration Hardware Support NVIDIA...

Which leaves Mojave and Catalina to the between?

No. Anything that requires METAL will not work.

OCLP makes the display to work with some sort of acceleration and with several caveats, but if an app requires METAL, it will not open, fail in weird ways or even crash.

With a Mac that you can't upgrade a GPU, the OCLP hacks and patches are a godsend, but for a Mac Pro where you can upgrade the GPU and have it completely and correctly working, it's just silly.

Okay, I hear you.

This just makes OCLP quite useless for vast majority of people who own old macs.
Like for iMacs from 2007 to 2011. All minis. MBP 2008-2016.
If they need Metal Apps...

I don't see the point of OCLP any more. Most of those macs that support Metal, are still supported by Apple.
Most benefit seems to be for iMac 2012-2015.

Am I wrong, if I guess that people don't need Metal-apps so much and use their OCLP-macs without just fine?

One more thing:
Flashing relys on running a python script.
That of course does not work with modern macOS.
What would be the latest macOS, where you could do this flashing?

Just get a cheap Kepler GPU, has Metal, draws way less current.

Really makes no sense holding on to a historic GPU if you want to run Mojave.

A GT640ish Kepler goes for about 40, so why fiddling with an unsupported GPU?

Update:
I flashed the 5870 and now it has boot screen.

Also, something unexpected: now 10.14 works with it.

I tried few xmrig settings and openGL works with some, but the switches in the openGL settings are undocumented and macOS becomes very laggy with 100% gpu usage. Something like one mouse click per 10 seconds.
But switching that openGL on in xmrig almost doubles the hashrate.

I hacked the newer version of gpu bios (012.020), which has settings of 950MHz for gpu and 1200MHz for its memory.
The original older bios's (012.018) settings were 875MHz and 1225MHz. (According to GPU-Z.)
I wonder does that affect anything to anything?
