All in all, it is what the title says. I hope that DirectX 12 is on the roadmap and hopefully as soon as possible. From what I understand DirectX 12 would allow the engine to utilize multiple cpu cores better than what is currently available in DirectX 11. I am aware that switching from DirectX 11 to 12 is a major step and requires A LOT of recoding, but with the pending release of the 3000 series GFX cards from Nvidia, DirectX 12 surely would be the best engine for the sim to take advantage of these, as well as the latest and greatest in the CPU world.
Although my knowledge is limited regarding game engines and DirectX 12 in itself, I do get the impression that significant perfomance improvements are to be expected if using DX12.
If anyone here has some more detailed information about what to expect from a DX12 application I would be happy to read it!
