Trigger checking is NOT related to FPS, as it runs in the FixedUpdate, as opposed to the Update. https://docs.unity3d.com/560/Documentation/Manual/ExecutionOrder.html FixedUpdate (and Physics) by default runs every 0.02 second. In Edit > Project Settings > Time you can adjust your Fixed Timestep. Alternatively, try changing the interpolation/extrapolation options in the Rigidbody (see docs for more details)
