Valve’s sequel, Portal 2, the critically acclaimed puzzle platform game, has received a new update that introduces support for Vulkan into the game. Most modern systems should have little problem running this nearly decade-old title (the old ATI Radeon X800 and NVIDIA GeForce 7600 are mentioned in the system requirements), but support for low-level APIs should allow Portal 2 to succeed on an even wider range of platforms and hardware, such as Linux and integrated GPUs.
The February 18 Portal 2 update also includes a long list of improvements and bug fixes, such as HighDPI support, the addition of 360-degree rotation, and the portal cannon now being affected correctly by dynamic lights. The full list of changes is below.

Players explore unseen areas of Aperture Science Labs and once again encounter GLaDOS, the sometimes deadly computer companion who guided them through the original game.
