Valve now shows the average framerate of games on the Steam Deck in the Steam Store, as Steam announces.
The data comes from players who opted in to sharing anonymized framerate data and is available for games with a Deck rating (Verified, Playable, Unsupported). It can be found on the store page under “Steam Deck Compatibility > Learn more”, including a histogram of the framerate distribution. Valve plans framerate data for more devices later; the opt-in in the desktop client is currently only in the Steam Client Beta.
Hello! With today’s update, you can now see the average framerate players get in games on Steam Deck.
This average is calculated using data from customers who have opted in to providing framerate data, and is available for games that have been tested for Deck compatibility (Verified, Playable, and Unsupported). As of this blog post, there are thousands of games with framerate data, and this number will grow as we continue to gather data. You can find average framerate data on each game’s Steam Store detail page under Steam Deck Compatibility > Learn more. This data is also available in your Steam Library on Steam Client Beta.
Framerate Histogram We’ve also added an expandable detail view with a histogram breaking down the percentage of data samples at each framerate. This is useful to see how the average is produced, as well as how often people are running into hitches or stuttering (which show up as small columns in the lower framerate values).
What’s next 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. This opt-in is currently only on Steam Client Beta, and will ship to all customers in the future.
