Valve has added framerate graphs to Steam Deck game store pages, displaying average frames-per-second recorded from players' actual handhelds across both OLED and LCD models. The graphs appear under existing Steam Deck Compatibility details alongside the current Verified, Playable, and Unsupported ratings.
Valve says the goal is to provide more precise performance expectations than the three-tier verification system alone. A game rated Unsupported might run fine in practice, while two Verified games could perform very differently. Framerate data offers specificity the current ratings lack.
However, Valve acknowledges the data may be skewed by V-Sync settings. This anti-screen tearing feature, often enabled by default, can force games into unrepresentative framerates. The Mortal Shell II results illustrate the problem: LCD Steam Deck versions show roughly 30fps, but OLED versions show around 45fps, a gap larger than the hardware difference justifies.
Valve plans to expand beyond Steam Deck. The company states: "We see this update as a stepping stone toward providing framerate data for more devices than just Steam Deck. To this end, we are also prompting customers to opt-in to providing anonymized framerate data in the Steam desktop client." The opt-in feature currently exists only in Steam Client Beta, with a future rollout to all customers planned.
