Game Ready Drivers provide the best possible gaming experience for all major new releases, including Virtual Reality games. Prior to a new title launching, our driver team is working up until the last minute to ensure every performance tweak and bug fix is optimized for the best gameplay on day-1. We have a discussion thread open on this driver here in our Nvidia driver discussion forums. For those that wonder, the DCH driver is a Microsoft DCH (Declarative Componentized Hardware supported apps) driver and refers to a new Windows 10 driver package preinstalled by OEMS implementing the Microsoft Universal Driver paradigm. While the base core component files remain the same, the way DCH drivers are packaged differs from previous Legacy (Standard) drivers. We recommend the normal driver and not DCH.
