7 Days to Die’s b257 experimental build adds FPS caps and a long bug list
The latest experimental branch update adds an in-game FPS cap, new sandbox options, and fixes for traders, maps, controller use, and vehicle inventories.

7 Days to Die has pushed out V3.0.0 b257 for its experimental branch, and this one is all about cleanup. The update targets player feedback, folds in new sandbox tools, and trims down a wide spread of bugs across combat, trading, quests, and UI behavior.
To hop onto the experimental build on Steam, players need to right-click the game, open Properties, head to the Game Versions & Betas tab, and pick latest_experimental from the drop-down. After that, the client will handle the download.
Among the additions, the update introduces an FPS cap setting, more localization work for clocks and calendars, and a handful of sandbox options that give players more control over loot, crops, and backpack restrictions. It also reworks several systems behind the scenes so those sandbox settings behave more consistently.
