- Looks like Valve's aware that we know that Panorama will be Happening® sooner rather than later in CS:GO and is waving a white surrender flag, as not only have [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/fbfeb181abdb70de3533920ccbe4091b2f62949b#diff-2376c954aec3534dcd1d16ff16959553R14639]numerous[/url] [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/fbfeb181abdb70de3533920ccbe4091b2f62949b#diff-2376c954aec3534dcd1d16ff16959553R20866]leaked[/url] [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/fbfeb181abdb70de3533920ccbe4091b2f62949b#diff-2376c954aec3534dcd1d16ff16959553R22293]strings[/url] from the Steam Translation Server made it into csgo_english, there is now also a new directory in the game's VPK structure containing all the map thumbnails in both 1080p and 360p resolution, under "/materials/panorama/images/map_icons/screenshots/"
- Some of you might be asking "wait, what's this Panorama thing everyone's talking about and so excited for?". Panorama is a UI framework developed in-house by Valve, which borrows concepts from both CSS and HTML. CS:GO currently uses Scaleform (another UI framework, developed by Autodesk), while both Steam's Big Picture Mode and Dota 2 use Panorama. Panorama is expected to bring many little quality of life improvements like eliminating microstutter between menus.
