Dude the difference between the ps5 and xsx is known they are completely different - underlying hardware the cpus are basically identical, the xsx gpu is not more feature rich, I wish you guys would just stop with this nonsense. They are both more than capable of pushing out 4K 60FPS and / or 4K 30FPS with limited ray tracing, Sony has already proven this with their 1st party games.
The SDK's used and the API's used are completely different, between Sony and MS. Sony uses its own SDK, Microsoft uses directx - the way they work are completely different, the way any game marks achievements / trophies and links into psn and xbl is also completely different - the controllers Sony's has far more features again the interaction is different.
This is known all third party publishers know they have 2 completely different beasts to build for and target and if it is also releasing on PC that again can be very different, for example on PC it might use Vulkan not directx, I'm not sure whether ms allows vulkan on the xsx I'm not sure if sony allows it (I doubt either do) - again does it work with steam or epic or their own publisher games store that will have completely different API interactions as well. Also generally speaking PC versions get released later, Rockstar is the perfect example they optimise for the consoles first and 6 months later they release to PC, or some will release on PC first and then later release on consoles.
In amongst all of this they now have to support 2 different profiles for xbox, they don't make anything extra for it, but have to optimise for 2 different hardware profiles - variation in ram, in bandwidth and in gpu strength the gpu in xss is 1/3 weaker in practically everything, the cpu runs slightly slower but that's nothing to worry about, its the gpu 20 cus at a lower frequency (the frequency reduction probably has a much bigger impact), the lower memory bandwidth, reduced mem size, so they have to optimise how they handle the data streaming, this will mean more time wasted for any xbox game - as I said right now I expect practically all game devs are middle fingering microsoft, more effort for next to no reward.
