Drivers should be the least of the problem for deploy-ready multiplatform engines. For the least, UE4 supports PC, XB1, and PS4. Plus, the engine is always PC-ready. The only time porting is needed is when they dig too deep into the engine, making things architecture-exclusive but even that can be dealt with earlier to remove the need to port. Otherwise, they can just let the engine do its stuff and build on multiple platforms without breaking a sweat.

Here's the flow: Epic Games manages UE4 (including drivers, builds, etc),

whereas at the same time PA uses the engine to build AC7 without potentially breaking down the engine into parts.

The game running at 60FPS could mean that either they do go deep or the engine itself is that powerful to begin with.
