Just like Valve said to us they would do so, Half-Life: Alyx is now available on Linux using the Vulkan graphics API. This arrives as part of a big update that went out today which also brings in modding tools and Steam Workshop support, it's going to be very fun to see what the community comes up with for Half-Life: Alyx.
For the modding side Valve released new versions of Hammer (the Source 2 level editor), a Material Editor, a Particle Editor, Source Filmmaker and more for people to tinker with. However, these tools are usually only available on Windows. Valve did say this is only the first Beta of the Alyx Workshop tools suite though, so we may see support for that too properly in future.
If you previously used the Proton compatibility layer to play Alyx, Valve said to follow these steps to reset it to the new Linux supported build:
- Go in the Properties for Half-Life Alyx by right-clicking the game in your Steam Library
- Check the "Force the use of a specific Steam Play compatibility tool" box
- Uncheck the box, and the download will properly complete.
For the Linux version, Valve are recommending an AMD GPU with the Mesa RADV driver for "best results". It may seem like Valve are giving NVIDIA the cold shoulder here but on Linux NVIDIA are missing some big quality of life features for VR. It will work with an NVIDIA GPU but the experience might not be great.
Really fantastic to see such continued Linux support from Valve. It was only earlier today in our round-up article that we listed it as an interesting upcoming game!
You can find Half-Life: Alyx on Steam, it requires a VR headset.
