This video introduces Valve's new standalone VR headset, the Steam Frame, which is presented as a versatile and high-performance successor to the original Valve Index. The headset features a lightweight, modular design with high-resolution 2160x2160 LCD displays per eye, pancake lenses, and refresh rates up to 144Hz. A significant innovation is its ability to operate as a standalone device powered by an ARM processor running a ported version of Steam OS. This allows it to play mobile VR games, sideload Android APKs, and run x86 Windows VR games via a new translation layer called "FEX."
For PC VR, the Steam Frame utilizes a revolutionary low-latency wireless streaming solution powered by a dedicated 6 GHz Wi-Fi dongle and a technology called "foveated streaming." By using integrated eye-tracking to send a high-bitrate video stream only to the user's focal point, it drastically reduces bandwidth requirements without a perceptible loss in quality. The video also details the new controllers, which include five-finger capacitive tracking and two-stage triggers, and highlights the system's extensive customization options, including an expansion port for future accessories.
Valve's Steam Frame: A Comprehensive First Look
0:00:09 Introducing the Steam Frame: Valve's new VR headset is a standalone, all-in-one device designed to be lighter, more comfortable, and higher fidelity than the original Index, challenging the dominance of outside-in tracking systems.
0:00:45 Three-in-One Versatility: The headset is a versatile platform capable of three main functions: high-end wireless PC VR streaming, native mobile VR gaming via its ARM processor, and running traditional x86 Windows VR games directly on the device using a new translation layer called FEX.
0:02:29 Lightweight and Modular Design: The headset is built in modules, including a core computer module weighing under 190g, a detachable audio system, and a counterbalanced rear battery pack for improved comfort and cable management.
0:02:56 High-Fidelity Optics and Display: It uses pancake lenses to minimize reflections and features dual 2160x2160 resolution LCD screens, capable of refresh rates from 72Hz up to an experimental 144Hz. Integrated eye-tracking enables advanced features.
0:04:08 Advanced Controllers: The new controllers offer five-finger tracking via capacitive sensors, two-stage actuating triggers and grips, magnetic thumbsticks for durability, and an estimated 40-hour battery life from a single AA battery.
0:06:05 High Degree of Customization: The system is designed to be highly customizable, with optional knuckle straps, alternative head straps, a spacer for glasses, planned prescription lens inserts, and an expansion port for adding accessories like color passthrough cameras.
0:08:34 Revolutionary Wireless PC VR: The headset achieves a low-latency wireless experience using a dedicated 6 GHz Wi-Fi dongle and "foveated streaming." This technology uses eye-tracking to send a high-quality video feed only where the user is looking, drastically cutting bandwidth needs with only 1-2 milliseconds of added latency.
0:11:55 PC Gaming on an ARM Device: A key software innovation is "FEX," an open-source translation layer that allows x86 Windows games (like Hades 2) to run directly on the headset's ARM processor and Linux-based operating system.
0:12:31 Full Steam OS Integration: The Frame runs a ported version of Steam OS, bringing desktop features like fast suspend/resume and performance overlays to VR. It also supports sideloading Android APKs, opening it up to a vast library of mobile VR content.
0:14:25 The Valve Index is Discontinued: With the launch of the Frame, the original Valve Index is now considered End of Life (EOL). However, Valve is open to other companies continuing the manufacturing and support of its ecosystem components like base stations.
