Akschually, Doom DA needs to have raytracing enabled at all times, and your vcard is in the first nvidia gen that has it. While 10xx and 20xx haven't shown much of a difference, and both series are still okay for average gaming, there's the planned divide vcard producers wanted. RTX IS ON ads visuals were fancy at best (imho) while consuming too much resources, and now there's the first game that doesn't function without it, pushing consumers to either updgrade their hardware or miss out on big hits. Not the first time it happened, but it gives a sense why there were a lot of media noise about that technology in the beginning.
