efficient access pattern for different dx11 memory types

chris_pn — Wed, 07 Apr 2021 10:45:56 GMT

Hi,

What's the efficient access pattern for the following dx11 memory types in compute shader:

Buffer

RWBuffer

Texture2D

RWTexture2D

For my understanding, data in Buffer and RWBuffer is arranged in row major order. Compared to them, Texture 2D and RWTexture is in tiling order. So they has different access pattern. But I can't find offical docs to approve my opinion and give a detailed description.

Thanks!

Hi,

Could anyone answer this question? I think It's really important and basic for dx11 shader programming.

Hi Mary,

Thanks for your reply. Could you explain the meaning of "peer-to-peer" here? I'm little understand.
