DYNAMIC_INDEXING is checked by default, since WGPU doesn't allow for any kind of specialization constants and constant indexing is nigh useless. STORAGE_RESOURCE_BINDING_ARRAY is enabled iff the device supports: - both or neither of uniform and buffer arrays with dynamic indexing; - both or neither of sampled and storage images with dynamic indexing. NONUNIFORM_INDEXING is enabled iff for ALL types of descriptor arrays *that are supported for dynamic indexing*, nonuniform indexing is also allowed. These flags have a limitation in that some platforms (eg. https://vulkan.gpuinfo.org/displayreport.php?id=11692#features_core_12) may support a strange subset of those features (example device supporting non-uniform indexing for textures and storage buffers, but NOT for storage textures or uniform buffers). In that case feature will be reported as missing, even though it is partially present. In the author's opinion, this flag set is convenient for the users to query; however, due to aforementioned limitations, it would be desirable to obtain statistics about "edge-case" platforms and what percentage of reports they comprise. |
