Lenovo announced at CES 2026 that it would be launching an official Steamos version of the Legion Go 2 gaming handheld, with a release expected around mid-2026. In advance of that launch, YouTuber ETA Prime tested Steamos on the original Windows version of the Legion Go 2 to gauge performance and overall experience. According to the testing, Lenovo and Valve’s work on Steamos support has resulted in an almost feature complete experience, with the only missing feature being software control of the RGB rings under the joysticks, while display brightness, networking, TDP and TGP controls, and performance profiles are reported to function comparably to Valve’s own Steam Deck.
Under Steamos, the Legion Go 2’s AMD Ryzen Z2 Extreme shows strong performance and efficiency across a range of games. The article states that even at a low 16 W TDP, running at 1600 × 1000 pixels with the Steam Deck preset enabled, the Legion Go 2 managed around 49 FPS in Cyberpunk 2077. When power is increased to 35 W in Performance mode and resolution is set to 1200p, the Z2 Extreme raises the frame rate to 61 FPS. The chip is also described as efficient, drawing just 9 W from the battery in Low Power mode while running lightweight indie titles at a locked 60 FPS, indicating that users can expect smooth gameplay without excessive power drain during less demanding sessions.
The handheld holds up particularly well in more demanding scenarios and compared with the Steam Deck. The article notes that Borderlands 4 runs at 57-60 FPS in Performance mode on the Legion Go 2 using the default Steam Deck graphics mode, while a referenced review found that the Steam Deck only managed around 20-25 FPS in the same title. Additional testing with Mortal Kombat 1, Spider-Man 2, and Doom: The Dark Ages showed that the Legion Go 2 maintained frame rates at or above 60 FPS even at the display’s native 1200p resolution, and with FSR enabled, Spider-Man 2 averaged above 70 FPS at medium settings and at 35 W TDP. Battery life results suggest solid endurance for a handheld of this class, as the Legion Go 2 achieved over seven hours of use in Low Power mode while playing indie games, dropped to two hours and 45 minutes for AAA titles in Balanced mode, and delivered a runtime of an hour and 20 minutes when running AAA games at the full 35 W in Performance mode.
