@dboyan I have run into a similar symptom (same error code) on my M1 Air when developing for [RBDOOM-3-BFG](https://github.com/RobertBeckebans/RBDOOM-3-BFG). In that case I was able to temporarily work around the...

> Indeed, the CTS test can pass by disabling argument buffers. Thanks @dboyan for verifying this. Hopefully @billhollings can find the issue with the argument buffers code path.

Just an FYI, but this WIP change breaks the _descriptorindexing_ example (using combined image samplers, but with variable descriptor count disabled on macOS) in Sascha Willems' [Vulkan](https://github.com/SaschaWillems/Vulkan) repo. Before: ![Screenshot...

Closing this since my main concern is covered in #2285: Should `MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS` be defaulted to 0 (i.e. disabled) on the iOS Simulator?

Thanks @SaschaWillems for adding this.

A side effect of the current project structure is a relatively long compile time. A clean build on macOS takes about 5 minutes on my 8700K machine (6x2 cores using...

@zarsr I ran into this same problem with MoltenVK when working on RBDoom3BFG, which uses Vulkan subgroups and the synchronization primitive `GroupMemoryBarrierWithGroupSync()` in a hierarchical depth buffer compute shader. The...

Thanks @SaschaWillems for the feedback. I am away on vacation this week, but will make the requested changes when I am back. UPDATE: Back now and changes submitted in https://github.com/KhronosGroup/Vulkan-Samples/pull/1187/commits/0dc49635f09d33687b3999869d2196d48fe06789.

> No idea why, but with this PR and the latest SDK (1.3.296) and in windows, this sample is now again running with less than 1 fps. Forcing it to...

Ok, I have rechecked this PR on Windows 10, and even fast-forwarded my local branch to current main HEAD just to make sure. I am using Vulkan SDK 1.3.296.0 with...
