Layers of abstraction aren't necessarily a problem if the designers care about latency. Oculus have invested huge resources in minimising latency, but most designers are fairly tolerant of latency if they can trade it off for increased throughput or lower development costs. We saw this particularly strongly with Android - circa 2011, Google realised that Android latency was having a major impact on UX, so they invested the resources to address it. Unfortunately, early architectural decisions meant that they never quite caught up with Apple, who had prioritised latency in iOS from the outset.
