no I can confirm that it work without gapps on Lineage… probably something else…

I’ll give a different perspective on what you said: dx12 basically moved half of the complexity that would normally be managed by a driver, to the game / engine dev, which already have too much stuff to do: making the game. The idea is that “the game dev knows best how to optimize for its specific usage” but in reality the game dev have no time to deal with hardware complexity and this is the result.
