Camera sensitivity decreases with more game objects on the screen?

I have a scene with a lot of cubes in it. The problem is that when I use my gamepad and a lot of those cubes are visible on screen, the camera moves more slowly. Can I fix this, or do I just need to increase the sensitivity?

 

You need to multiply your movement and rotation by Time.deltaTime

This is a known thing in game development, basically you have to ensure movement is time based, not frame based. https://unity3d.com/learn/tutorials/modules/beginner/scripting/delta-time

 

I'm very new to coding and I'm just using the default MouseOrbit.js script. Would I have to change the script, or just add a new script to my camera?

 

I can't help you learn to code, I'm sorry. But there are a lot of tutorials around for it. There's a lot to learn, so http://unity3d.com/learn section is there if you're serious.
