Horizon Forbidden West was ported from PS to PC. Decima is an engine from Sony’s first-party studio, so it's understandable that their development process would lean more towards PS's internal architecture rather than the more common GPUs on the market. Of course, even general-purpose engines can perform better on PS5, AMD, or NV. But, for these engines, they have less information about how customers will use the engines, so there's less infomation can be used to optimize. On the other side, customers using these engines often don’t have enough experience optimizing sufficiently for each platform. None of this is absolute, but I think this logic is reasonable.

For game developers using these engines, if they take optimization seriously, they typically make adjustments to lighting, LOD, loading, and model details or shaders on console platforms to achieve a similar visual effect while meeting the targeted performance goals. This is why you usually get better performance on a console at the same price point compared to a PC, aside from the subsidies provided by Sony.
