Valve's puzzle-platformer-teleportationer Portal 2 (opens in new tab) was released to great acclaim on April 19, 2011. It was a tremendous success, and remains popular to this day. According to SteamCharts (opens in new tab), there are at this very moment more than 3100 people playing it—not bad at all for a decade-old puzzle game.
It's not just gamers who keep playing with it: So is Valve, which dropped a new update (opens in new tab) yesterday that, among other things, adds support for Vulkan rendering, improves advanced video setting descriptions, makes default video settings "smarter," and speeds up the compile time for user-made Perpetual Testing Initiative (opens in new tab) puzzles.
Here's the full rundown of what's changed:
- Implemented a Vulkan render backend (currently accessible through the -vulkan command line parameter).
- Improved compile time for Perpetual Training Initiative puzzles.
- Improved advanced video settings descriptions.
- Made the game Hi-DPI aware.
- Smarter default video settings.
- Improved resolution of player avatars throughout the game.
- Players can now be invited to play co-op on controller.
- Button text contrast and padding has been improved when using a controller.
- Implemented a 360° Spin action.
- The portalgun is now correctly affected by dynamic lights (projected textures) in the scene.
- Improved client-side prediction for coop play.
- Added the ability for workshop levels to pack particles into their map with a particles/map_manifest.txt
- Misc. rendering optimizations.
- Added an icon to the game on Linux.
- Removed the "Trading Coming Soon" button.

- Fixed a crash if PeTI avatars could not be retrieved.
- Fixed Cave Johnson's lines not progressing when playing queued workshop levels.

- Fixed the OnFiredPortal2 output not firing.
- Fixed some text being duplicated on the screen multiple times.
It's not clear why Valve is still patching Portal 2—I respect the dedication, but it is a 10-year-old game—but this isn't actually as out-of-nowhere as it might seem. Valve has been slowly, but fairly steadily, releasing Portal 2 patches since mid-2017, the last one a smaller scale fixer-upper that landed in July 2020.
