To play Half-Life: Alyx, you need a Windows PC that meets Steam’s listed minimums and VR hardware that works with SteamVR. Steam lists Windows 10, an Intel Core i5-7500 or AMD Ryzen 5 1600, 12 GB of RAM, and a GeForce GTX 1060 or Radeon RX 580 with 6 GB of VRAM. Valve Index is not required: Valve says computer-connected VR hardware that works with SteamVR works with the game. Valve’s current page also says Steam Frame can stream the game from a PC or run it standalone; check the latest product information because that capability may change.
What do I need to play Half-Life: Alyx?
The standard setup is a PC that meets the game’s minimum requirements, a SteamVR-compatible headset, and tracked controllers supported by the headset. Steam labels Half-Life: Alyx VR-only and lists SteamVR and tracked-controller support. The game is not playable as a conventional flat-screen PC game using only a monitor, mouse, and keyboard. Steam’s store listing is the source for the minimum PC requirements and VR support labels.
Valve’s broader compatibility guidance is simple: “If you have VR hardware that works with a computer, then it works with SteamVR.” Valve’s Half-Life: Alyx VR page applies that rule to the game. It does not mean every headset has identical tracking, controllers, setup steps, or availability; check the specific headset’s requirements before buying accessories.

| Component | Steam-listed minimum |
|---|---|
| Operating system | Windows 10 |
| Processor | Intel Core i5-7500 or AMD Ryzen 5 1600 |
| Memory | 12 GB RAM |
| Graphics | NVIDIA GeForce GTX 1060 or AMD Radeon RX 580, with 6 GB VRAM |
| VR platform | SteamVR |
These are the specifications on the Steam listing accessed October 4, 2026. Meeting them is a baseline for compatibility, not a promise that a particular headset will run at its maximum refresh rate or resolution.
Minimum requirements versus high-refresh performance
Valve’s Steam Support performance guidance says complex VR gameplay can keep an eight-core CPU and a 12 GB GPU completely busy at up to 144 Hz, and encourages players to use advanced performance options. That is performance context from Valve, not a revised minimum and not a prediction that every PC or headset can reach 144 Hz. The actual workload and achievable refresh rate depend on the hardware and settings in the individual setup. See Valve’s Half-Life: Alyx performance tips.

Can I play Half-Life: Alyx with my VR headset?
Start by confirming that the headset works with SteamVR on your computer, then verify the required controllers and tracking equipment for that exact model. Valve says computer-connected VR hardware that works with SteamVR works with Half-Life: Alyx, but its page is not a complete model-by-model compatibility list. Controller styles shown by Valve include finger-tracking and trigger-based input, so do not assume every headset provides the same controls.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsHeadsets and bundles can differ in whether tracked controllers or tracking hardware are included, and in connection requirements. For example, Steam Support’s Index guidance says the Valve Index headset uses DisplayPort 1.2 or higher and works with original Vive Base Stations or Base Station 2.0. It also says the Index headset is compatible with Vive and Vive Pro wands as well as Valve Index controllers. Those details apply to Index; they are not general requirements for all SteamVR headsets. See Steam Support’s Valve Index compatibility information.

Do I need a Valve Index?
No. Valve Index is one SteamVR option, not a stated requirement. Valve’s compatibility rule is based on whether the computer-connected VR hardware works with SteamVR. When comparing a headset or bundle, check these practical differences rather than treating one model’s accessories as universal:
- SteamVR compatibility: Confirm the exact headset can use SteamVR with your PC.
- Controllers and tracking: Check what is included and whether the headset needs separate controllers or tracking hardware.
- Connection: Verify the headset’s required ports, adapters, wireless equipment, and PC connection method.
- PC capability: Compare your computer with the game’s minimum specifications and consider that higher refresh rates may demand more performance.
- How the game runs: Determine whether the headset streams from a PC or, if explicitly supported, runs the game standalone.
Does Half-Life: Alyx need a gaming PC?
For a conventional PC VR setup, yes: the PC must meet the Steam-listed minimums and connect to a SteamVR-compatible headset. A powerful PC below the listed minimums may still encounter compatibility or performance problems; the minimum list is the appropriate starting check, not a guarantee for every combination of headset and settings.

Steam Frame: Valve’s current standalone and streaming claim
As of Valve’s Half-Life: Alyx VR page accessed October 4, 2026, Valve says Steam Frame can either stream Half-Life: Alyx from a gaming PC using its included wireless adapter or run the game standalone without a host PC. This is a product-specific, time-sensitive claim. It does not establish standalone play for other headsets, and buyers should confirm Valve’s current Steam Frame details before purchase.
Can you play Half-Life: Alyx sitting down?
Yes. Valve lists sitting/standing and roomscale play arrangements, so roomscale is an option rather than a universal requirement. The VR page also lists teleport, shift, and continuous movement. These choices let players select a play-space and locomotion style, but they do not guarantee that a particular setup will be comfortable for every player.

Before starting, select a play arrangement and movement method that suit your available space and headset setup. If you plan to use roomscale, ensure the headset’s tracking system and play area are configured according to that headset’s instructions.
Which accessories should I buy?
There is no universal accessory list for every headset. Start with a complete, compatible headset setup rather than buying generic add-ons: confirm which tracked controllers, tracking hardware, cables, adapters, or wireless components the chosen model needs and whether they are included in its bundle. In particular, do not buy Vive Base Stations, DisplayPort equipment, or Index controllers unless the specific headset and configuration call for them.
Valve Index is one documented example with its own connection and tracking requirements; other headset models may use different systems. The available official information does not establish a current market-wide compatibility matrix, regional availability, or prices for headset bundles, so check the manufacturer’s current specifications and SteamVR support information for the exact model you are considering.
