Funny that these guys are doing the investigative piece when the likes of AT just regurgitate info fed to them.
With GPUView for full access to the rendering pipelines, Maxwell is aware of Async Compute queues when its requested, but it shoves them into the same single graphics pipeline. It's as what the guys on b3d have been saying.

The benchmark uses up to 18% compute but it only uses 1 parallel async compute queue, or 1 ACE only, in it's current form. Now this data falls in-line with what Zlatan has said when he disabled AC, performance drops by around that mark, more than the 5% Lionhead told journalists.
18% uplift + multi-threaded rendering explains the strong performance of AMD GCN in a UE4 game, where the deficit is normally quite big. Can't wait to see some more DX12 titles in neutral engines.
