+### Troubleshooting: performance
+
+The default settings work for most users however if you are using a less powerful computer or one without a dedicated graphics card (as is the case on many laptops), you may wish to adjust the graphics settings to enable the simulation to run faster.
+
+If you find that the simulation runs very slowly we suggest disabling both Ambient Occlusion and Shadows.
+These should not affect the behaviour of the simulation, only the rendered visuals.
+
+To do this on Windows, open webots and go to the menu **Tools** → **Preferences** → **OpenGL**, then set **Ambient Occlusion** to "none" and check the box next to "Disable shadows".

 Within the Webots IDE, there are a few different panels:
 
 - In the centre of your screen is the 3D simulated view of the arena.
+  It can be useful to change your view into the world using the [camera controls][camera-controls].
 - On the left is a tree hierarchy of all elements in this "world".
 - On the right is a text editor which you can use to develop your code, however we recommend using a dedicated [code editor]({{ site.baseurl }}/tutorials/editors/) if you can.
 - At the bottom is the console, where output from your robot code will be displayed.
 - At the top are your general controls which include the time controls. Press the centre play button to run the simulation at normal speed.
