Indeed, but people will buy whatever is available, even with an inferior feature set, albeit it has more VRAM.. so that's nice.
DLSS must really be becoming a pain point for AMD, NVIDIA are on track for vastly increased adoption, and the current list is already good and just keeps growing. If you had a capable card, and a supported game, you'd be mad not to use it, unless you're already WELL above your personal target FPS and IQ. Every person I know that actually own an RTX card likes DLSS and knows it has a tonne of promise (for continued adoption), even in edge case where artefacts are caused over native, the performance uplift mitigates that and then some. Like usual the only arguments I see against it, come from people who don't use it and I don't care for their opinion on it whatsoever, it carries 0 weight.
AMD really need to step up on this one. I don't see their solution being as effective as DLSS 2.0, but if they can make it 'universal' then that's a massive win in itself. They also have the benefit of being late to the market with it too (as has happened in the past), so they get to learn from the mistakes NVIDIA made trailblazing it (DLSS 1.0).
