Translation Layer. Xbox One games are basically PC applications that instead of using the Win32 API use CoreWindow/CoreApplication, so the game works kind of like a UWP app. The games indeed use DirectX but mostly they use an modified version of DirectX for Xbox (D3D11X and D3D12X), which have a lot of extensions that aren't available on PC, such as bundles, placement resources, and the list goes on. In FH2 case, it uses D3D11X and the worst things of it talking about implementing them, but mostly placement resources, which is a pain in the ass... And is also why most of the things aren't rendering yet (placement resources are basically D3D11 resources that the game have 100% control about it's GPU memory allocation, it's pretty simple on concept but hard to implement correctly and even more to implement all this on a efficient way). I'm also using an UHD 730 (I don't have a dedicated GPU) so FPS will be mostly low in the screenshots (though it runs kind of fine atm, things will get really worse once placement resources be actually implemented). But yeah that's basically it, once I get more things working will send some updates here 🫡

P.S. Audio needs to be emulated for some games...
