Source9Measurementpcgamer.com/hardware/gaming-pcs/atomman-g1-pro-reviewRead 15 October 2026All rows at 1440p from the review's gaming charts, on the review's default profile. Cyberpunk 2077 uses the Ray Tracing Medium preset. The upscaling row uses DLSS Quality with frame generation x2 (CNN model) per the text. Black Myth: Wukong's upscaling row is described only as DLSS. The review does not state upscaling for Avatar, Baldur's Gate 3 and Metro Exodus, so none is stored. Tom's Guide also publishes 1080p results but names neither the preset nor the power mode, so they are not stored.

Source4Reviewpcgamer.com/hardware/gaming-pcs/steam-machine-review-2026Read 10 October 2026PC Gamer tested the 2 TB Steam Controller bundle. Valve and Tom's Hardware state that the 512 GB and 2 TB models are identical apart from storage, so CPU, GPU, memory and cooling match. The 1440p rows come from PC Gamer's gaming benchmark suite and the Steam Machine is the first entry of each chart. Cyberpunk 2077 uses RT Medium and the review text names FSR Quality with no frame generation for the upscaled run. The review does not name the upscaler for Black Myth: Wukong. Other rows do not state upscaling.8Reviewgamersnexus.net/pre-built-pc/valve-steam-machine-review-gpu-cpu-benchmarks-steamos-test-thermals-noise-and-priceRead 10 October 2026GamersNexus tested the 512 GB model on SteamOS with MangoHud, out of the box. Resolution and settings come from the chart titles. Every row is average FPS. The 1 percent low is stored only where the text states it. Starfield 1% low is 25 FPS (0.1% low 18). Cyberpunk 2077 RT Medium is 22.8 FPS after Valve's last-minute ray tracing patch (20.7 before). Black Myth: Wukong 1080p High raster with Medium RT and FSR Quality is 16.7 FPS after the patch (13.8 before). The Oblivion Remastered text says no upscaling. Other rows do not state upscaling. Rows with SoftwareRT in the preset use software ray tracing and have no ray_tracing flag.

The Black Myth: Wukong gaming run is stated only as about 20 to 21 dBA, so it is not stored as a row. Idle is stated as the room noise floor with no dBA value.
