Titlebar Statistics

In the Editor Preferences window, search for and enable the Show Frame Rate and Memory option. This can be found under the Performance section. Once enabled, multiple helpful statistics will be displayed in the top right of the Editor’s title bar.

These statistics are —

Frame Rate & Frame Time

The Frame Rate and Frame Time statistic covers the current editor frames per second and the time is takes to render a single frame. These are the two same stats that are available when using the stat fps console command.

Memory Usage

The Memory statistic displays the amount of RAM the opened Unreal Engine editor is currently taking.

Object Count

The Object statistic displays the total number of object that have been claimed by the editor. This is the total size of the global object array minus the number of available object array elements.

It’s important to know that this isn’t just the objects within the loaded level, but the editor as a whole. For example, a blank level wouldn’t lead to having zero objects claimed.

Stalls

New in Unreal Engine 5, the Stalls statistic displays the total number of times the engine has stalled during the current editor session. The stall counter will go up when the engine’s instance has been non-responsive for at-least 5ms.

If this statistic is increasing, then the editor might be constantly under heavy load due to a complex project or hardware limitations.

Conclusion

While simple, these metrics are persistent and will prove to be quite helpful keeping track on how well your project is performing during development.
