Because you are offloading GPU tasks to your CPU (which isn't built for heavy 3D rendering), your frame rates will likely drop to single digits. It's often called a "slideshow emulator" for a reason.

“FPS is 2 – is this normal?”

Some games utilize low-level DX12 features (like Async Compute) that may still crash or fail to render even with emulation enabled. Alternative Methods:

Force a game to run a particular version of DirectX / Direct3D

The "dxcpl" utility stands for "DirectX Control Panel." It is a legitimate tool distributed by Microsoft as part of the Windows SDK (Software Development Kit) and the DirectX Developer Runtime. Its intended purpose is not for the end-user consumer, but for the developer. It allows developers to toggle debugging layers, configure the "Feature Level" of the hardware, and simulate specific software environments to test how their applications handle errors.
