Intel's woes with ARC stem from the fact their silicon straight up doesn't support anything below DX12, so they have to rely on software emulation for them. Nvidia and AMD both support DX versions below DX12 in their silicon, they don't have to emulate anything which means better performance. Even if Intel had access to Nvidia and AMD's driver source codes, none of it would be useful because they don't have the silicon.
