Client CPU Time is the average number of milliseconds an experience spends doing client work in each frame. Roblox notes that 60 fps requires total CPU time below 16 ms; rising values appear to players as lower frame rates, hitches or stutter.
The Total view stacks five categories: Scripts, Networking, Physics, Animation and Miscellaneous. Selecting one exposes subcategories such as RunService.Heartbeat, while filters cover platform, operating system and memory group. Roblox's example traces a jump to roughly 26 ms to pathfinding running every frame, then confirms the fix after throttling it.
The chart lives under Monitoring > Performance on the Client tab and reports minute-by-minute averages. Data is available from June 17, 2026; Roblox says sampling will increase over the following two weeks and client-memory categories are planned next.
