Game Packaging - for NON-RTX users?

I am able to package a game in DX12 mode. The glass is 100% ray traced and refractive. It looks great when using an RTX card.
People without an RTX Card will see a broken glass - because their graphic card does not support DX12 and RTX.

Question:

  • What can I do before packaging, to make sure that NON-RTX users can also see a good glass material?
  • Do I have to add a Sphere Reflection Capture?

Will that even work? Or any other options?

Thank you very much for any suggestions and thoughts!
