Valve's puzzle-platformer-teleportationer Portal 2 was released to great acclaim on April 19, 2011. It was a tremendous success, and remains popular to this day. According to SteamCharts, 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 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 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.

- Fixed a crash if PeTI avatars could not be retrieved.

- Fixed rumble not being respected for respective players in split-screen mode.
- Fixed the wrong avatar being used if playing coop after playing a workshop level.
- 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.
