async != DX12, nikdo nevi, jak moc 'zasadni' async v DX12 nakonec bude.

jinak Pascal ma nezanedbatelny narust vykonu (temer stejne velky jako Polaris) v Time Spy, pokud je async zapnuty, ono to s tou implementaci mozna tragicke nebude. i v AotS (worst case scenario pro nV) Pascal zvlast nezaostava

"Ultimately, 3DMark aims to predict the performance of games in general. To accomplish this, it needs to be able to predict games that are heavily optimized for one vendor, both vendors, and games that are fairly agnostic. 3DMark is not intended to be a measure of the absolute theoretical maximum performance of hardware."

"Futuremark’s formal statement and updated technical guide contains a great deal of additional information on how asynchronous compute is executed on Maxwell, Pascal, and AMD GPUs. Again, there’s simply no evidence that this test is unfairly or unusually biased towards any vendor.

The only thing this benchmark shows is that Pascal can see a modest improvement with async compute enabled. Given the still-early state of DirectX 12, the limited number of games that utilize it, and the fact that only two engines we are aware of have been written for low-overhead APIs from the ground up (Oxide’s Nitrous engine and Time Spy itself), concluding that this benchmark is biased simply because it shows a small gain for Pascal is extremely premature.

Even 12 months after launch, DirectX 12 support in shipping titles is still limited, and our ability to characterize what DirectX 12 performance will look like across the entire industry is similarly constrained. With Pascal just launched and AMD’s Vega arriving later this year, there’s going to be ample opportunity to watch how the API evolves."
