[−] Expand description

Scenarios of how resources use memory.

Variants

Private

[−] Expand description

Full speed GPU access. Optimal for render targets and persistent resources. Avoid memory with host access.

Dynamic

[−] Expand description

CPU to GPU data flow with update commands. Used for dynamic buffer data, typically constant buffers. Host access is guaranteed. Prefers memory with fast GPU access.

[−] Show fields

Fields of Dynamic

sparse_updates: bool

Optimize for multiple disjoint small portions to be updated, as opposed to big linear chunks of memory.

Staging

[−] Expand description

CPU to GPU data flow with mapping. Used for staging data before copying to the Data memory. Host access is guaranteed.

[−] Show fields

Fields of Staging

read_back: bool

Optimize for reading back from Gpu.
