On Twitter I see a lot more people shitting on Series S|X than PS5, now I'm no Microsoft fan but that console has far superior backwards compatibility to begin with, and they have plenty of older games with "FPS boost". Sony doesn't seem to want to do this and I don't get why, it's entirely possible and would probably help PS5 sales.
Worst part is you just know Sony will go out of their way to try and patch around this.
It's not that Sony doesn't want to. Backwards compatibility between Xbox 360 and modern consoles is possible because the architecture between them is similar, whereas the PS3 is too different to PS4/5.
As for FPS boost, it depends on the developer, not Sony.
I think the hate for Xbox is mostly because they lack good first party titles. Most of them bombed. Remember Halo Infinite and Redfall?
Yes the architecture is different but that's not the point I'm trying to make. Microsoft are actively pursuing backwards compatibility and trying to make it better, FPS Boost and enhanced resolution are both such prominent features that they're advertised on the Xbox store for each game that has them.
It's something Microsoft is pushing for, FPS Boost was developed by the Backwards Compatibility Team, they then work with developers to implement it with past games. PS5 has Game Boost but aside from it just being there Sony isn't offering the same assistance for developers to improve older titles, if this was an Xbox game you bet Microsoft would be helping to implement FPS Boost and get it to 60fps.
