Developers still can use PS4 engines to make games run natively on ps5 without using any of extra features such as ray tracing or GE , ( my guess is GPU scrubber too).I don't understand the confusion here on this. Backwards compatibility is simply running the same code from the previous generation without alteration. If your hardware allows such games to run at 60fps instead of 30fps, that's good, but it's BC. This is why for example, the PS5 GPU still has the PS4 GPU's instructions buried in it. In BC mode, the PS5 can execute that code, just at a vastly faster rate of speed (if allowed). THAT is backwards compatibility. A PS4 game and game code, cannot access features of the NEW GPU that it did not have instructions for.
Now these "patches," I'm not clear on how they are working. Have we seen or had published that these patches are actually a port of the central engine or game engine code to the PS5? Or is there some way to 'piggyback' the new instructions into that code quickly? Bottom line, if the code has been recompiled for PS5 then it is not BC.
To an extent I see the issue...how do you have 'next gen' patches that still use the same graphic modes as on PS4, just better performance? Isn't that BC? I don't know that we have this clarified, but I think simple logic and common sense indicates that a small patch is NOT the same as a game being developed from the ground up for either XSX or PS5. I'm betting that Sony has simply engineered the tools to where just the core game can be recompiled for PS5 and take advantage of a limited and easily implemented set of improvements. Then developers can release the patch and all the same PS4 graphical assets, etc. can be used by the "new" version of the code. That's my guess. So it's not TECHNICALLY BC, but it is definitely not a full remake of the game with the PS5 as the target. In other words, the patch that makes say Man-eater a "PS5 game" is not taking advantage of and not a PS5 specific application like Demon's Souls Remake is.
