Although it’s true that DirectX12 offers opportunities for better performance by allowing developers a lot of low-level control of graphics device, it also means that application needs to do explicitly a lot of book keeping and validation that video drivers used to do for us. Using Gamebryo can eliminate this kind of tedious work from developers while still obtaining all the benefits of DX12. Also Gamebryo abstracts away architectural differences between DX11 and DX12 like the removal of immediate context, so Gamebryo can help developers move to DX12 in the least intrusive way.
