Modern Warfare 4 splits its DLSS 4.5 features three ways by GeForce generation
Nvidia has split Call of Duty: Modern Warfare 4's DLSS support three ways, and which part a GeForce owner gets depends on which generation of card is in the machine. Nvidia's own post on the game, dated October 6 and re-read at 21:09 UTC on October 8, sets out the tiers in one passage.

Super Resolution comes first and is not tied to a generation: "In all modes, DLSS 4.5 Super Resolution will accelerate gameplay and enhance image quality." Then the ladder starts. "On GeForce RTX 40 Series systems, DLSS 4.5 Frame Generation will further boost frame rates. And on GeForce RTX 50 Series systems, players can activate Dynamic Multi Frame Generation, with up to 6X multiplication."
Reflex sits outside the ladder. Nvidia says it "can be enabled on all GeForce RTX systems", which makes it and Super Resolution the two features the post names for every RTX card, with each generation above adding one more.
The 50 Series gets the multiplier, the 40 Series gets the frames
So an owner's card decides which half of the feature set is reachable. A 40 Series machine gets Frame Generation; only a 50 Series machine gets the up-to-6X multiplication, which Nvidia describes as "an ideal balance between image quality and performance" rather than attaching a figure to it.
Nvidia names only the 40 and 50 Series in those two clauses. It does not say what an RTX 20 or 30 Series card gets beyond Super Resolution and Reflex, it does not say why the line falls where it does, and it makes no claim about older cards in either direction.
The top tier is tied to a specific setting in the game: Nvidia calls the 6X multiplier "perfect for maximizing frame rates when using Call of Duty: Modern Warfare 4's optional ray-traced reflections". Optional is Nvidia's word. Nvidia publishes no frame rate for the game, for any card, so the tiering is the only hard detail the post carries about performance.
Early access on October 16, with Nvidia's own escape clause
The dates come with a caveat attached by Nvidia rather than by anyone reading it. Campaign Early Access "begins October 16th* for all pre-order customers, featuring our suite of DLSS 4.5 technologies, followed by the full launch on October 23rd that adds multiplayer and DMZ". The asterisk resolves to Nvidia's footnote: "Actual Play Time Subject to Possible Outages and Applicable Time Zone Differences. Actual platform availability and start date subject to change."
Early access is the campaign alone, so the tiering applies to a single-player run first and reaches multiplayer and DMZ a week later. Pre-ordering is the only route in on October 16, and Nvidia's footnote covers the possibility that the date moves.
DLSS 4.5 is Nvidia's wording throughout the post, and nothing in it speaks to any other DLSS feature. The driver side is settled: GeForce Game Ready 617.42, released on October 6 for this game, was still the newest Game Ready and Studio driver in Nvidia's download lookup at 21:19 UTC on October 8.
The hardware floor comes from the publisher rather than from Nvidia: Activision published the game's PC requirements while its Steam page still said TBD. A GeForce owner asking what frame generation this game will give them therefore has two documents to read and three possible answers, and the one that applies was decided when the card was bought.
