Your operating system (OS) requires an update.Your graphics card (GPU) is running with outdated drivers.Here are some cases in which the problem might occur: It indicates that the application engine you are currently running is unable to use Direct3D Feature Level version 10.0. When trying to run games and other applications that require extensive graphical processes, you may receive an error message “ DX11 feature level 10.0 is required to run the engine”.

Solution 2: Update your Graphics Card Driver.

MiniTool provides you some solutions to this issue here. It is usually caused by a missing or corrupted graphic card driver but you can fix it easily. We'll keep you updated as Dx12 progresses.Some users report that they receive a problem “DX11 feature level 10.0 is required to run the engine” while trying to run a game. Intel plans to release the demo for consumer use along with DirectX 12, but that's still a ways out. An increase in CPU power efficiency can be used for more performance even if an application is not CPU bound.'' GPU bound' are misleading on modern devices like the Surface Pro 3. The main takeaway is that power and performance are inseparably linked. Spreading work across more CPU cores at a lower frequency is significantly more power-efficient than running a single thread at high frequency. 'These increases in power efficiency in DirectX 12 are due both to reduced graphics submission overhead and to an increase in multithreaded efficiency. Intel had this to say about the experiment: Aside from obvious performance gains in the FPS department, this could potentially allow more power-constrained users to game without draining the battery too quickly.

The power consumption graph (below) shows a heavy dip when switching to Dx12 from Dx11, implying that Dx12 is better optimized and requires less of the hardware to produce the same results. In a further demonstration, the company locked the framerate in both Dx11 and Dx12, forcing an identical workload on the CPU's IGP.
