SteamOS vs. Windows on dedicated GPUs: It's complicated, but Windows has an edge
SteamOS underperforms Windows on systems with dedicated 8GB GPUs, fares better on integrated GPUs, and more frequently encounters apparent GPU RAM limits.
Why won't Steam Machine support HDMI 2.1? Digging in on the display standard drama.
SteamOS compresses luminance with chroma subsampling to deliver higher resolution and frame rates over limited HDMI 2.0 drivers, reducing color fidelity and VRR support.
Testing shows why the Steam Machine's 8GB of graphics RAM could be a problem
8GB of GPU VRAM is increasingly a performance bottleneck on SteamOS, causing greater slowdowns than equivalent Windows configurations at higher resolutions.
The Steam Frame is a standalone VR headset that streams PC games via a wireless dongle and runs many Steam titles locally using Arm-based real-time emulation.
