Asked what kind of scalability the PC port offers over the PS4 original, Kojima Productions technical director Akio Sakamoto is emphatic: "High frame-rate for sure! As we had originally designed the game in 60fps, this is a feature that I must say out loud! Of course, it is not locked to 60fps, and according to your hardware, it can go much higher." Based on our hands-on experience with the game, the studio more than delivers - and in ways that we didn't expect. Upon loading up the game, the first surprise is that we have a Sony-developed engine running on PC under a Microsoft graphics API: DirectX 12. Bearing in mind that older PC Decima engine revisions (for development purposes) ran under OpenGL, we fully expected Vulkan as the API of choice.
It seems that development of a PC rendition of Decima continues at Guerrilla for production purposes, as Sakamoto continues: "We already had the PC version of Decima as a development tool. But concerning the graphics side, to have the performance running as good as on the PS4, we needed to develop in a way that we could utilise the most out of DirectX 12. At that time, not much information was available for DirectX 12, so this was the most difficult part."
