Ke kauze Async compute. Ukazuje se, ze mel starej hnizdo zase jednou pravdu.
Async Compute Only Boosted HITMAN's Performance By 5-10% on AMD cards; Devs Say It's "Super Hard" to Tune

"it’s quite surprising to read that even AMD cards merely got a 5-10% performance boost, especially after AMD endorsed HITMAN’s implementation as the best one yet. Async Compute, which has been used for SSAA (Screen Space Anti Aliasing), SSAO (Screen Space Ambient Occlusion) and the calculation of light tiles in HITMAN, was also “super hard” to tune; according to IO Interactive, too much Async work can even make it a penalty, and then there’s also the fact that PC has lots of different configurations that need tuning."
"Saying that Multi-Engine (aka Async Compute) is the root of performance increases on AshesOfSingularity between DX11 to DX12 on AMD is definitely not true. Most of the performance gains in AMDs case are due to CPU driver head reductions. Async is a modest perf increase relative to that."
tl;dr Jake prekvapeni, AS nejen ze neni svaty gral DX12, ale je to mnoho voseru pro nic. Nedivil bych se ani trochu, kdyby se nvidia na AS uplne vykaslala, usetrila slozity kus kremiku, a vyhrala to hrubou silou.
Takze kdo zral AMD tuhle PR kauzu, je za vola, vcetne celeho tydiitu.
