You said RTX accounts for 66% of all Nvidia GPUs sales, making it seem like most Nvidia customers are choosing RTX (for RT). I'm simply saying that Nvidia customers who want a certain level of performance have no other option than RTX. If there were variants of the 20xx cards without RTX then we might see what the real value of RTX is among customers - my guess, very little. As I stated before here and elsewhere, raytracing may be the future but that future is a very long way away. As for DLSS, that's nothing more than a bad joke.
