Raytracing was merged into Dev-Rendering!

Hi,
I have a few questions:

  1. I have an Nvidia Titan Volta. With this card has to work raytracing in ue4.22 preview7?
  2. I installed and runned in dx12 mode, I see that it’s working in output log.
  3. But Unreal crashes in dx12 mode if I press any button.
    I don’t know if it is because of Titan Volta not an RTX card or just because of Windows10 dx12 or Unreal preview7. So If I wait will it be good in the future, or I won’t be able to use Titan Volta for 4.22.
    Thank you for answer
