Camera's inertia modifies speed and rotation?

Questions

My team is using a project that runs with a very low frame rate (there are a lot of heavy models).
I’ve noticed that in that case the camera inertia increases a lot. Apparently it’s tied to the FPS.

So I’ve decided to reduce the camera’s inertia (from 0.9 to 0.35) to overcome this effect.
However the camera’s speed and rotation are reduced a lot if I do this.

Is this normal? I could increase the camera’s speed and angular sensitivity to compensate.
But camera’s inertia should only impact the inertia, not the speed.

Yeah, the inertia value is used to calculate the fall off for both rotational movement and directional movement. It does feel like the inertia shouldn’t be having that much of an effect on movement but adjusting the speed and sensitivity is the best way to counteract that.
