The minimum specs for Half-life: Alyx have been revealed. Valve’s “killer VR app”, a prequel set between the events of Half-life and Half-life 2, is available across Steam VR-compatible headsets and will require just the bare minimum of last-gen mainstream graphics card grunt in order to run.

Half-Life: Alyx will only be available to play in VR, and could single-handedly sell more VR headsets than all other games on the platform put together. If you rank among the fans waiting patiently for over a decade, and are perhaps a little worried for your gaming PC’s aptitude for VR, don’t fret. Valve has published the minimum spec for its upcoming Half-life game and they are none too distressing for even modest rigs built in the past few years.

Starting with the graphics card, you’ll need an Nvidia GTX 1060 6GB or AMD RX 580 8GB minimum in order to boot Half-Life: Alyx with any hope of reasonable frame rates, according to the Steam store page. We don’t yet know what performance these mainstream cards will net you in-game. That will depend on the refresh rate your chosen virtual reality headset is capable of. For example, the Valve Index is capable of up to 144Hz across its twin panels – thirsty work for even the best graphics cards.
