Sehr schlechte OpenCL Performance

Zitat von DevFelixJava

I remembered that MacPro7,1 caused some issues and that only my current smbios worked properly. The IOREG is definitely with NRX disabled. (As you said, just one monitor and no hardware acceleration)

i do not know if NOOTRX needs to use ImacPro 1.1 Smbios

For your CPU is more appropriate to use MacPro 7.1 Smbios

i would try to use in this way if possible

Happy you solved initial problem but i think is it possible to improve your system configuration

the only problem could be your <GPU acpi address

others parameters are the same for all people who use to spoof their GPU

EDIT

i see you have acceleration using NootRX kext but only low performance

try to recreate that condition and only to disable to that config algrey fix pat and enable Shaneee fix pat

you would see a great improvment in performance

I was never able to run my 6900 XTXH with NootRX. I always came back to using Whatevergreen + device-id BF730000. But you have to have the correct PCI Path. That’s crucial.

SchmockLord your XTXH has a device id not supported by osx AMD gpu driver

So you have to spoof it to a supported one by this driver

6950 xt is not supported in any osx

So we have to spoof to a supported device id from a supported 6900 xt (different but similar to a 6950 xt)

Luckily it works

I can use also NootRX but i prefer to spoof and use whatevergreen kext

DevFelixJava user has a pci acpi path in his ioreg i cant understand for my limited acpi knoledge and also his pciroot address seems doesnt work. It is weird so for now he had success using NootRX and overall Shaneee kernel fix patch to boost opencl/gl performance
