So far, I went ahead to look to some guys actually working with the tech (not disclosing who), but the thing is that the current titles in development are showing poor performance 35-48 FPS @1080p on the RTX 2080TI card, but this mostly because drivers and SDK are still in alpha, so long way till final product. The titles which are targeting RTX will launch with Raytracing disabled and added later as a patch.
