Valve's latest hardware offering, the Steam Frame VR headset, is now available, completing the company's current lineup. In a recent interview, Valve software developers Pierre-Loup Griffais and Jeff Leinbaugh shed light on the headset's design, development, and future aspirations. Valve envisions the Steam Frame as an evolving platform, aiming to build upon its capabilities over time, much like the Steam Deck.
The developers emphasized that the Steam Frame was designed with a wireless experience as a primary goal, addressing a significant usability barrier. While a wired mode exists, accessible through a developer toggle, the focus remains on wireless streaming. This is further supported by an included adapter intended to ensure a baseline wireless performance regardless of individual network configurations. "We see the Steam Frame as a streaming first headset," explained Leinbaugh, highlighting the aim for a wireless VR streaming experience for most users. However, he also noted that the headset's identity could shift as standalone compatibility grows, similar to the early days of the Steam Deck.
Regarding the headset's internal specifications, Griffais stated that significant product redesigns were not feasible at later stages of development, even if a less powerful, lower-cost version might have been considered. "Despite being streaming first, the ability to run things locally has been pretty well used in our observation and play testing," Griffais added, indicating satisfaction with the trade-offs made to accommodate both streaming and local play.
The technical implementation of SteamOS and Proton on the Frame's ARM architecture was a significant undertaking. Griffais detailed how Proton has been rebuilt natively for ARM, with a translation layer called FEX handling x86 emulation. "All the Proton code is native for the platform," he stated, noting that performance penalties from ARM translation are avoided once the game operates on the native ARM side. While compatibility is largely similar to the Steam Deck, performance can vary due to differences in GPU architecture and CPU translation characteristics. Valve also dedicated considerable effort to optimizing graphics drivers for desktop-like games, a task not typically prioritized on mobile chipsets, leveraging Linux and Mesa's open-source nature.
Valve has made strides in enabling demanding titles like Half-Life: Alyx to run natively. Griffais suggested that further performance improvements for Alyx would likely come from application-side tweaks, though driver optimizations are ongoing and learnings are being applied to other games. The process of optimizing Alyx also provides valuable insights into ensuring a good standalone VR experience, a different challenge than optimizing non-VR games through Proton. "Comfort is a bigger factor" in VR, Leinbaugh noted, emphasizing the learning curve in setting appropriate performance thresholds for VR titles.
Addressing the headset's $1,059 price point in comparison to competitors like the Meta Quest 3, Griffais stated that Valve does not typically engage in direct comparisons, instead focusing on delivering features that benefit Steam users. He highlighted the Frame's comfort, weight, and optical quality as key attributes. The price, he explained, is a direct reflection of the hardware's cost. Supply chain issues, particularly memory costs, have impacted the final price, a situation mirroring broader market trends affecting other hardware, including the Steam Deck.
Valve prioritized software compatibility at launch, aiming for the largest possible library of games available to play or stream. This focus on game accessibility was seen as the primary value proposition, offering a wide range of options, including both VR and non-VR titles. Leinbaugh mentioned that while there are no immediate plans for accessory battery packs, the modular design of the strap allows for future possibilities, including options for extended battery life or improved audio solutions. Third-party accessory development is also encouraged, with at least one partner already working on enhancements for the front port.
Nvidia driver support on SteamOS remains a work in progress, with Valve dedicating significant resources to improving it. "It's definitely at the top of our list," Griffais said, noting that the team has been working on it for years. While basic functionality has been enabled, performance parity with the state of the art is still a target.
Both developers described varied personal usage patterns, ranging from playing 2D games on a virtual screen to full VR immersion. Griffais expressed excitement about future possibilities, including augmenting 2D streaming with features like stereo 3D effects, a concept previously explored in other display technologies. Leinbaugh sees potential in VR mod conversions and features that enhance the viewing experience, from simple HUD adjustments to full stereo depth. He views the Steam Frame as a platform that can evolve, with both Valve-driven updates and community contributions playing a significant role. Griffais echoed this sentiment, describing the Frame as a "canvas" with extensive possibilities for extending the Linux desktop into VR and for game modding, while still maintaining that the headset is a "fully formed offering as is."
