At the Qualcomm Tech Summit that is currently happening in Hawaii, they revealed that PUBG Mobile will get support for true 10-bit HDR and a 90fps mode. This will come thanks to their newest chip the Snapdragon 865. Which will be powerful enough to handle 90 fps and 10-bit HDR.
Also the new 10-bit HDR will definitely offer better dynamic range than the HDR mode that PUBG Mobile already has.
With this new changes we will have to wait and see what will this mean for the future of PUBG Mobile Esports.
