Am i wrong or both of you are talking the same thing in different words?
If the game is running in BC mode, even in PS5 CPU/GPU clocks, is still PS4 code, compiled in PS4 SDK. Rocket Leagle and Cyberpunk 2077 are examples. No 120fps, no Ray Tracing, no Geometry Engine, no settings improvements, no better resolution.. only PS5 horse power pushing to fixed 60fps.
If the game is not running in BC mode, it's compiled in PS5 SDK, different ID. Destiny 2 and Borderlands 3 are good examples. But Destiny 2 and Borderlands 3 has the PS4 code too. I can play 2 games: Destiny 2 ported to PS5 and Destiny 2 in BC mode.
This guy gets it.
Nope.
PS4 SDK has a option to make it aware of PS5 hardware.
You are just confusing things.
PS5 has 4 modes (3 BC modes + 1 native):
BC PS4 Mode
BC PS4 Pro Mode
BC PS5 Mode ------------ this is the BC PS4 games are aware of PS5 hardware (it can even have menu options only show running on PS5)
PS5 Native Mode
Rocket League is definitively running in BC PS5 Mode... it is not running native... developer confirmed it... it uses the power of PS5 thought PS5 BC Mode but BC modes are limited for example BC doesn't allow 120fps no matter how light your game is... you need to make a native PS5 port for that.
We’re more or less saying the same thing,

The sole bone of contention is that in the BC PS5 mode (as it’s a BC mode) software cannot possibly know it’s running on a PS5. It’s still a PS4 binary. Binaries by definition are hardware specific.
BC PS5 mode simply allows for full CPU and GPU clocks, but it’s still a BC mode so to the game, the game thinks it’s running on a PS4 Liverpool APU, but with 3.5GHz and 2.3GHz CPU and GPU clocks respectively.
What determines whether the game runs in which BC mode is not the game code compiled into the binary. It’s the API meta-data that tells the OS “hey, I’m a PS4 game and I can run in the following modes:...” and the BC software in the PS5 OS says “OK, i’ll run you in X mode”.
The nuance that you’re missing is that in ALL BC modes, the PS4 game (patched or otherwise) doesn’t know it’s running on PS5 hardware, in that it doesn’t have access to PS5 specific hardware features.
I think if a ps4 game needed the ps5 sdk it had to have a new sku, its own download on the psn store and be completely different from the ps4 version.
Games like dirt 5, borderlands 3 and Spiderman miles have you download the ps5 version of the game even if u have the ps4 version installed.
That's different from ghost of tsushima which has a ps4 patch telling it to detect the ps5 hardware so it can run at an uncapped framerate
I’m not arguing that PS4 games can be patched into PS5 binaries. Well they can in theory, but Sony has chosen for ease and clarity of distribution not to do it that way.
My argument is that only PS4 games recompiled into PS5 binaries actually “see fully” and have full access to the PS5 hardware they’re running on.
