to je sice čístečně pravda, ale díval ses, co je podstatou toho tzv. DX12_1? Jedná se o nepodstatné funkce, které si u MS protlačila nvidia a dají se velmi efektivně implementovat softwarově.

If you own a GCN 1.0, Fermi, or Kepler card, you’re going to get the DirectX 12 features that matter most. That’s why Microsoft created feature levels that older GPUs could use — if Fermi, Kepler, and older GCN 1.0 cards couldn’t benefit from the core advantages of DirectX 12, Microsoft wouldn’t have qualified them to use it in the first place.
