hey people,
i’m not super into these things but apparently there is a feature in Metal called „Argument Buffers“ which is also accessible in MoltenVK and drastically increases the max sampler count. (useMetalArgumentBuffers)
/**
* Controls whether MoltenVK should use Metal argument buffers for resources defined in
* descriptor sets, if Metal argument buffers are supported on the platform. Using Metal
* argument buffers dramatically increases the number of buffers, textures and samplers
* that can be bound to a pipeline shader, and in most cases improves performance. If this
* setting is enabled, MoltenVK will use Metal argument buffers to bind resources to the
* shaders. If this setting is disabled, MoltenVK will bind resources to shaders discretely.
*
* NOTE: Currently, Metal argument buffer support is in beta stage, and is only supported
* on macOS 11.0 (Big Sur) or later, or on older versions of macOS using an Intel GPU.
* Metal argument buffers support is not available on iOS. Development to support iOS
* and a wider combination of GPU's on older macOS versions is under way.
*
* The value of this parameter must be changed before creating a VkInstance,
* for the change to take effect.
*
* The initial value or this parameter is set by the
* MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS
* runtime environment variable or MoltenVK compile-time build setting.
* If neither is set, this setting is enabled by default, and MoltenVK will not
show original
could this be an easy fix for us mac users or lies the problem deeper ?
