No Man's Sky Unveils 'Cosmos' Update: Revolutionizing Space Exploration with New Features and VR Optimizations
September 9, 2026
No Man’s Sky drops Cosmos, a major free anniversary update that overhauls space exploration with customizable space stations, modular orbital bases, asteroid mining, salvageable hulks, expanded Star Maps, new hazards, and a range of activities.
A new alliance feature enables cross-player collaboration, with leaderboards possible to highlight top alliances.
Players can own Space Stations as trade hubs and participate in a new player alliance system, setting the stage for player-led civilizations.
There’s a nuanced debate over eye-tracking requirements for PC VR, noting PSVR2 on PC lacks eye-tracking and this affects feature availability across setups.
Performance notes show smooth 2560x1400 gameplay on Steam Deck/Steam Machine at High with FSR 2, though a Steam Input bug affects button mappings with a workaround by changing input modes.
Cosmos adds Steam Frame PCVR support with foveated rendering to boost performance by concentrating rendering where the user looks.
PC VR support now includes foveated rendering, building on prior KI upscaling in the Voyagers update and aligning with expectations for Steam Deck and future Steam Frame hardware.
The patch leverages eye-tracking for high-quality rendering in the user’s central vision, signaling broader optimization for VR ecosystems.
Update notes reference earlier patch 5.20 and credit Renu from UpdateCrazy for coverage.
Emojis serve as a credible signal rather than confirmation of features, with the studio known for revealing details close to launch to manage expectations.
Changes are viewed as positioning No Man’s Sky for a potential Steam Frame launch, given rendering improvements and hardware discussions.
There’s continued silence on Light No Fire, though the project remains actively in development.
