It's not uncommon to see a new game title come out that touts that the "best" experience will be on either AMD's or NVIDIA's (or Intel's in rarer cases) GPUs, but it is uncommon to see a game engine as a whole being given the nod by its developer to one or the other. In this case, the engine is Unreal Engine 4, and it s developer, Epic Games.
At the ongoing Game Developers Conference, Epic announced a new licensing program for UE4, and its expanded support for Android. Overall, UE4 promises some amazing things, and if anyone out there has ever run the Citadel UE3 demo on mobile, you can probably get an idea of what's to come - graphics that are closer to PC levels than ever before.
Epic also announced UE4's tight integration with NVIDIA's solutions, with CEO Tim Sweeney saying, "Epic developed Unreal Engine 4 on NVIDIA hardware, and it looks and runs best on GeForce." Given the fact that game engines don't get much better than UE4, that's quite the ringing endorsement.
Of course - there's a reason Epic chose to use NVIDIA cards so intently: NVIDIA GameWorks. This is a solution that ties in well with UE4 to give developers easy access to some of NVIDIA's special effects, such as with HairWorks, WaveWorks, PhysX, and the variety of additional tools, including Tegra Graphics Debugger.
At this point, the only thing that could make me more excited for UE4 games to get here is if one of them happened to be Unreal Tournament 4.
