AMD GPU Drivers: The Real Truth. - Page 26

Ugh, doesn't AotS also use async compute in DX12 while it doesn't in DX11?

DX11 can still use it, it just works differently.

There is only one submission thread to the GPU in DX11, so Async's advantages are limited.

Dx11 use a serial pipeline so async = for no reason

Serial pipeline=Single submission thread

we are saying the same thing.

No we dont. The whole point of async is to use 2 pipelines the same time. In dx11 you need to change between graphics pipeline and compute on the draw call. So no there is no limitation because there is no async at all.

I can assure you, async is available in dx11.

AMD didn't create ACEs for the hell of it way back with 7xxx

There is just very limited use cases where it has any advantaes.

It is my job but tell me. Provide me info that is even possible and i will eat my shoe if you do this.

Just to understand what are you saying. Async is when you use 2 pipelines or more at the SAME time. And you say that dx11 with a single pipeline can use async. Not even unreal 4.9 support async properly and it's only available as a dx12 feature. You cant build your exe as dx11

ACEs werent used for graphics. With ACEs you can create general compute workloads that can share many compute pipelines that can work together.

Also Fermi used something similar to GCN ACEs.
