Microsoft unveiled Windows 11 last night, and in doing so mentioned new gaming-focused features.
Windows 11 automatically adds high dynamic range (HDR) enhancements to games built on DirectX 11 or higher that previously only used standard dynamic range (SDR). HDR allows a supported game to render a much wider range of brightness values and colours. It's a tech already in the Xbox Series X and S. Microsoft mentioned over 1000 games will support auto HDR, including Age of Empires: Definitive Edition, Rocket League, DayZ, and even Doom 64.
Microsoft said Windows 11 will load new games faster via tech called DirectStorage. Again, this was a part of Xbox Series X and S tech. DirectStorage means games quickly load assets to the graphics card without bogging down the CPU. Microsoft said to expect incredibly detailed game worlds rendered at "lightning speeds" and without long load times. "DirectStorage Optimised" Windows 11 PCs are configured with the hardware and drivers needed to enable this.
