That’s basically the notes in their entirety. It should also slightly reduce system memory usage. The patch notes state that this release fixes a DirectX 12 start-up crash, and reduced CPU usage when running the game in DX12 mode. Since the changes are all DX12-related, this probably only downloads for players who have chosen to use the DX12 preview branch. There’s a new, DirectX 12-focused patch out for Deus Ex: Mankind Divided today, which should improve performance for those opting to use that API.
