XR-131: Display Mode Support for Game DVR and Screenshots *

  • Artigo

Version 1.0, 3/1/2020

Titles must ensure that Game DVR and screenshots work properly across display modes and types. Titles that display in HDR do this by rendering both the SDR and HDR swap chains, because the SDR swap chain is used for SDR screenshots, broadcasting, and Game DVR.

More Information

Starting in 1706 XDK QFE 2, titles that display in HDR may choose to have the Xbox console platform perform automatic tone mapping for the SDR swap chain by setting the DXGIX_SWAP_CHAIN_FLAG_AUTOMATIC_GAMEDVR_TONEMAP flag. While this option satisfies XR-131, we recommend that titles perform tone mapping manually for the highest image quality and best performance.

Intent

Ensure that, when users are using 4K or HDR, their screenshots or game clips appear correctly on non-4K and/or non-HDR displays.

Certification Test Cases
