Bug Fixes The renderer fallback now also covers the window being recreated, such as a resolution or renderer change, rather than only Defcon starting up. HDR for Metal (MacOS) and Vulkan (Windows, Linux) no longer creates corrupted and garbled screenshots. World messages such as launch alerts no longer stay on screen over the menu after you leave a game. The lobby window now appears as soon as you start a game, instead of there being a 500ms - 1 second delay. Defcon now closes straight away when you quit, instead of pausing first. Connecting to a multiplayer game no longer freezes the globe in the menu or makes the UI fade update extremely slowly. Graphics Changes Defcon now has new map graphics, updated to match the same visual style as the old graphics but higher quality. The legacy graphics can be toggled back on inside Options -> Graphics -> Map Quality if you do prefer the old look....
