I agree, patched from developers of each game is needed. PSSR ML is like some one courting a girl but still not opening up her door. PSSR ML can't do its trick as long as developers have not sent a patch especially for frame rate. I think Sony and developers are aware of it, and in a few months will see more updates and upgrades to each game. The Ps5 pro life cycle will be constant improvement and adjustment by PSSR ML, but that will happen if developers will uncage there games, especially frame rate capped.This doesn't work like that. PSSR is not trained on specific games (like DLSS 1.0 was).
For sure there will be new versions of PSSR but games will have to be patched (most likely).
