CDPR quite literally made it clear these past years they are ditching the "PC first slash down for consoles later" approach for the better current "Console first scale up for better hardware later" approach.
They did this to stabilise development and testing, so they don't repeat another situation where Witcher 2, Witcher 3 and Cyberpunk 2077 released with technical faults.
They also did this because they have a 15-year contract with Epic Games to market UE5 development merging tech/ideas between CDPR and Epic Games (such as merging RED Engines TurboTECH into UE5.6 ).
UE5 targets PS5 hardware which is AMD RDNA2 (it can do Next-Gen DX12 features such as Hardware Raytracing and Mesh Shading - Nanite Rendering of Geometry, Foliage and Shadows | Witcher 4 uses all of this.)
Which GPU are they going to target? The dead 5090? 😂
Good luck getting it to work on the switch 2 which is what they want. Square is will learn a bad lesson from this. Just like how cd projeky red decided to forgo the PC as a baseline going forward.
