Judging by the first reviews, the update has achieved its goal: support for a high frame rate has appeared (previously the game could not output more than 62 frames / s), problems with lag and slowdowns during detention / inspection have disappeared.
Besides the engine change, patch 1.4.9 brought fixes of minor logical, graphical and audio issues and also delivered Papers, Please with translations into three more languages: Korean, Turkish and Czech.
So far, these innovations have only debuted in the Steam version of Papers, Please (Windows, macOS, Linux), but will be coming soon GOG and Humble. Some of the fixes will also appear on sooner or later Android.
