Consider Downgrading MoltenVK to 1.2.9 to fix crashing

[yippeeeyay]

Firstly, hope you're doing well, and congrats on getting the app to the App Store!

Newer versions of MoltenVK (1.2.10+) have an issue with Metal Argument Buffers, which causes incorrect rendering of graphics and crashing especially on older Apple GPU devices (A12 and older). In emuThree, A12 and older Apple devices will either crash or have incorrect texture rendering when starting a 3DS game.

Metal Argument Buffers only became enabled by default starting with MoltenVK 1.2.10

Here are some issues opened by the developers of DolphiniOS and Retroarch for iOS on this specific problem:
KhronosGroup/MoltenVK#2403
KhronosGroup/MoltenVK#2395

Downgrading to MoltenVK 1.2.9 would be beneficial as it would stop the crashes on Apple A12 GPU devices and older and also potentially solve graphical issues that are present on newer devices as well (mostly for 3DS).

If you do not want to downgrade, you can also disable Metal Argument Buffers by setting it to 0 instead of the default which is 1.
MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS=0
(The MoltenVK docs describe how to edit the config)

Hi,
I recently installed the App Store build of Provenance on my A11 iPhone 8, but the app will not launch, instead crashing instantly. Could this issue be related to the problem I'm having?

I am running the latest iOS 16 version and have Provenance updated to the latest version (3.0.1) by the way

Consider that your device is too damn old. The latest IOS is IOS 18.2.1. Your’re not on the latest IOS, because your hardware isn’t even supported by Apple anymore.

I acknowledge I have old and unsupported hardware and pretty ancient software but considering the most recent system Provenance emulates is the PSP, which came out 13 years before my iPhone 8 and has far worse performance, I don't think my hardware is going to be a problem. If you're gonna be this unhelpful, please do not bother replying at all.

Screw this I'm using RetroArch

I'll look into this. The newer Molten added a big performance boost to 3DS on my devices.
If i can disable or build my own from source that could work perhaps.
