Patch 2.3 (Age of Empires II)

New Options: Gameplay Modification: Bugfixes: Other:
 * Object Shadows Anti-aliasing (Enabled by default in builds prior to 2.2 for the improved shadows). Disabling may help improve performance & allow for expanded GPU support with some older Shader model versions.
 * Enable VSYNC option (can help reduce load on higher end GPUs)
 * Clamp mouse to window when in foreground
 * Quick match speed default to normal but can be changed to fast
 * Display mode options from main menu: Windowed, Fullscreen, Fullscreen Desktop (for multi-monitor)
 * Fullscreen desktop requires monitors to have matching vertical resolutions. Mismatched resolutions resulted in truncated UI and was disabled. You can still drag the game in windowed mode across multiple monitors.
 * Added nine additional grouping hotkeys and made group creation / selection keys modifiable.
 * After getting the patch you may be forced to re-create your hotkey file.
 * Group hotkeys can be changed by accessing options -> Hotkeys -> Game Commands.
 * Group Selection hotkeys cannot be modified by alt or shift keys, as these keys have special meaning in game (e.g. alt + group selection key = select and center on)
 * If multiple buildings of the same type are selected, unit training will sequentially be divided amongst buildings (Multiple building unit queues)
 * Missing grey background behind some tooltip text resolved (to improve text clarity)
 * Localization fixes
 * Unlocalized Launcher Buttons
 * Missing campaign text
 * Unlocalized Russian UI
 * Additional various localization fixes
 * Additional Achievement fixes
 * Trebuchet attack range fixes
 * Various campaign crashes due to string length overflows
 * Game ‘win’ counter should increment correctly
 * Quickmatch Map Size properly filters based on map size chosen
 * Performance warning typo fixes
 * Fixed AI files not being unpacked properly from workshop mods
 * Fixed workshop downloading only one update per launch of the game
 * When getting booted from the game, you will return to the main menu. This is by design due to the gameflow and how the title processes game information.
 * Gameplay version changed to 2.3
 * Matchmaking settings changed to the ‘widest’ setting permitted by Steam’s system.
 * Users may see different game lists for several reasons including:
 * User location (the system should return games that present a better play experience first)
 * Game legitimacy
 * Steam account standing
 * Filters
 * Please note when joining games that high pings may result in poor gameplay experiences.
