What is FPS?
FPS stands for frames per second. It refers to how many frames the viewer tries to render each second while the model is being viewed or navigated.
In 3D Repo, FPS Settings help control how the viewer balances smooth navigation with model visibility.
When navigating a large or complex model, the viewer needs to process a lot of geometry. If the device cannot keep up, navigation may feel slow or delayed.
FPS Optimisation helps manage this by targeting a set frame rate. To maintain that target, the viewer may reduce how much model detail is displayed while moving through the model.
FPS Target | What it means in practice |
Lower FPS Target | More model detail may remain visible while navigating, but movement may feel less smooth. |
Higher FPS Target | Navigation may feel smoother, but less model detail may be visible while moving. |
Benefits of FPS Settings
FPS Settings help improve model viewer performance by controlling how many frames are rendered per second.
Benefit | Description |
Improve viewer responsiveness | Limits unnecessary frame rendering so the model can respond more consistently during navigation. |
Reduce lag on large models | Helps prevent the viewer from trying to render more frames than the device can handle. |
Support lower-spec devices | Allows users to choose an FPS target that is better suited to their device performance. |
Improve review sessions | Provides a steadier viewing experience when navigating models during coordination or review. |
Default FPS Settings
FPS Optimisation is enabled by default in 3D Repo and uses a default FPS Target of 20 FPS.
The FPS Target controls how the viewer balances movement performance with the amount of model detail shown while navigating.
20 FPS is used as the default because it keeps navigation responsive without forcing the viewer to reduce too much visible detail when working with large or complex models.
A higher FPS Target, such as 60 FPS or 120 FPS, may make navigation feel smoother, but less model detail may be visible while moving. A lower FPS Target may keep more detail visible, but movement may feel less smooth.
20 FPS is not a maximum value. Adjust the FPS Target based on the device performance, and required viewing experience.
Enable or Change FPS Settings
Access Basic Settings.
Locate FPS Settings.
Use FPS Optimisation to enable or disable the setting.
NOTE: FPS Optimisation is enabled by default. When enabled, the viewer will use the value set under FPS Target.
Enter an FPS value suitable for the device being used.
NOTE: The default FPS Target is 20. FPS Target only applies when FPS Optimisation is enabled.
