DLSS 4- Massive Framerate Increase! Is there a catch?

With the RTX 50 series announcement, we got some amazing performance claims, but they all relied on the new DLSS 4 multi-frame generation technology. That left me with a lot of questions about what would be the latency and image quality penalties for enabling multiple generated frames between each rendered frame. We now have some additional information from Digital Foundry's early access testing using DLSS 4 on the new RTX 5080.
