I mean, the standard for mmo is fps over anything. I'm not sure that people would prefer raytracing over DX12 or textures upgrade, or even nvidia DLSS support.

Getting a hold of a raytracing card is a $800-$2000 commitment. Even RTX 2080s are not that cheap to come buy, much less RTX 3080s. Even when they're not a rarity they're still $500+. I myself will try to get a 3080 next year, but I truly see raytracing being the same fad 4K has been, a pipedream that will take a decade to be realized.
