MP 7,1 Thunderbolt eGPU on 7,1?

[mattspace]

Just wondering if anyone has used a TB eGPU on a 7,1. From the perspective of running low on slots, and thinking if it could be a way to feed an old GPU like a GT120 to a VM for a legacy OS version to use, without getting into issues with having an old GPU permanently mounted inside the box.

I had a pretty solid reality check of my archival workflows in a VM project, when I realised in old versions of Photoshop, there's a whole bunch of things that won't work, or show up (like layer effects) because they're directly rendered with GPU.

I see a ProxMoxBox future for my machine...

I dont know why you would tbh, if you have a higher end GPU just replace the W5700X a 6900XT (max you can put in 7,1) is much faster and you can get rid of the MPX modules

Well the point is to get graphics acceleration to a vintage OS - is a 5700 or anything going to be able to provide OpenGL acceleration to an OS which doesn't have drivers for it?

My guess would be probably not.

I tested my Radeon RX 7900 XTX in macOS. It booted, and let me log in. But it was unbelievable how slow it was. Even opening Finder, or browsing the Settings.
I never seen anything like that with a graphics card in Windows, before installing the proper drivers.

That's because there's no drivers for it.

The last highest end card macOS supports is the 6900XT. Some people flash the 6950XT to make it work, but it's not worth the little 2-4% in performance increase.

Yes

Yes

How? My current VMWare setup isn't passing through any hardware acceleration to Snow Leopard, but if there's a different virtualising solution that can pass through emulated hardware acceleration, that the VM will see as the real thing, I'd love to hear about it.

Virtualising Intel macOS on Intel macOS is becoming very dificult to research as search models break down under slop, and AS / UTM crowds out results.

boot in safe mode you'll probably experience the same thing.
