In this interview, the CEO of Epic Games (Unreal Tournament, etc.) predicts the game engines of the future may be using software rendering due to increasing CPU performance which eliminates the need for an API. GPUs are evolving into generic array processors which could even run the Linux kernel some day.
TG Daily: What kind of advantage can be gained from avoiding the API? Most developers just utilize DirectX or OpenGL and that's about it. How does the Unreal Engine differ from the conventional approach?
Sweeney: There are significant advantages in doing it yourself, avoiding all the graphics API calling and overhead. With a direct approach, we can use techniques that require wider frame buffer, things that DirectX just doesn't support. At Epic, we're using the GPU for general computation with pixel shaders. There is a lot we can do there, just by bypassing the graphics pipeline completely.
