[−] Expand description

How this memory will be used regarding GPU-CPU data flow.

This information is used to create resources (see gfx::Factory).

Variants

Data

[−] Expand description

Full speed GPU access. Optimal for render targets and resourced memory.

Dynamic

[−] Expand description

CPU to GPU data flow with update commands. Used for dynamic buffer data, typically constant buffers.

Upload

[−] Expand description

CPU to GPU data flow with mapping. Used for staging for upload to GPU.

Download

[−] Expand description

GPU to CPU data flow with mapping. Used for staging for download from GPU.
