Valve officially released a new update for the incredible VR game Half-Life: Alyx, bringing support for the Steam Frame in standalone mode. Not just that though, there’s some other nice improvements to the game that remains one of my all-time favourite gaming experiences when I played it through on the Valve Index.

Optimizations for Steam Frame

• Made significant rendering and performance optimizations when running on Steam Frame, updating most of the engine without altering any of the content.
• Added foveated rendering support when running standalone on Steam Frame.
• Ported the game to ARM64/aarch64.
• Added support for depth reprojection when running on Steam Frame, allowing smooth gameplay at lower framerates.

General Fixes

• Additional performance improvements when running on desktop PCs.
• Removed 1 tick of latency on player hands and other simulated objects.
• Fixed some GPU configurations displaying a low-memory warning when they had plenty of memory available.
• Fixed cross-platform cloud saves on Linux.
• Fixed subtitles not appearing on Linux.
• Fixed the Main Menu flickering for some users.
• Fixed a bug where it was occasionally not possible to interact with items when starting a new game.

I might have to do another play-through whenever I manage to get a Steam Frame, and perhaps dive into some of the bigger mods for it too. Exciting!

You do get a free copy of it when you buy the Steam Frame too so that’s nice.
