## Topics

### Store actions

[`MTLStoreAction.dontCare`](/documentation/Metal/MTLStoreAction/dontCare)

The GPU has permission to discard the rendered contents of the attachment at the end of the render pass, replacing them with arbitrary data.

[`MTLStoreAction.store`](/documentation/Metal/MTLStoreAction/store)

The GPU stores the rendered contents to the texture.

[`MTLStoreAction.multisampleResolve`](/documentation/Metal/MTLStoreAction/multisampleResolve)

The GPU resolves the multisampled data to one sample per pixel and stores the data to the resolve texture, discarding the multisample data afterwards.

[`MTLStoreAction.storeAndMultisampleResolve`](/documentation/Metal/MTLStoreAction/storeAndMultisampleResolve)

The GPU stores the multisample data to the multisample texture, resolves the data to a sample per pixel, and stores the data to the resolve texture.

[`MTLStoreAction.unknown`](/documentation/Metal/MTLStoreAction/unknown)

The system selects a store action when it encodes the render pass.

[`MTLStoreAction.customSampleDepthStore`](/documentation/Metal/MTLStoreAction/customSampleDepthStore)

The GPU stores depth data in a sample-position–agnostic representation.
