The Witcher 3: Wild Hunt has been updated to support graphical options on the Xbox One X.
The game running on Xbox One X now includes two new options in the settings: 4K Mode and Performance Mode.
4K Mode runs the game in 4K resolution (super-sampled on a non-4K display) with 30fps. Performance Mode enables dynamic scaling (1080p to 4K depending on load) and targets 60fps. HDR is supported in both modes.
Enhanced shadows, ambient occlusion, higher resolution textures, and texture filtering is added as well.
CD Projekt Red also plans on releasing a new PlayStation 4 Pro patch to add HDR support.
