I understand the reticule being a 'guide' for the mech's computers to follow, but nothing actually showing where the weapon is presently aiming, which is where you'd see your reticule bounce, is just silly. Something as simple as little crosses + + + would suffice in showing the aimpoints of weapons on the left arm, torso, and right arm. These bounce around and move independently of the actual aiming reticules, and only when they're lined up will you make a properly aimed shot.
Which would then be called an CCIP, or Continously Computed Impact Point sight: it shows the gunner where the weapon(s) will impact if (s)he would press the trigger at that moment of time. This has the benefit of giving instant feedback as to what the current firing solution is. Of course, this is only a guestimation even with 5th generation fighters: a lot of parameter values like crosswind, air humiditiy or even the exact range (Radar/Lidar isn't all that accurate for a bunch of physical reasons) are subject to measurement errors or plainly not available.
Most if not all mentions of Mech targeting systems in the TT sourcebooks indicate that the standard 'Mech sight is indeed a CCIP. (to quote: "The Mech's weapons will hit whatever the pilot points the crosshairs at, be it rock, tree, or enemy 'Mech"). So by principle, a CCIP sight
must bounce deliberately (moved by the computer) since 'Mech movement influences where weapons point at. Of course, as was mentioned, having a usable CCIP sight for 9, 10 or more independent weapons (and even different ballistics!) is a usability engineer's nightmare...
But, CCIP thus does not necessarily show you a
valid firing solution. Leading a moving target is still the gunner's job, unless (s)he also has a LCOS (Lead Computed Optical Sight) at his/her disposal, which shows where the craft/weapon needs to be pointed in order to hit. To my understanding, that is what a dedicated targeting computer provides. Although "realistically", LCOS on ground vehicles would be hideously inaccurate due to ground clutter, multi-path propagation, beam scattering etc. going on with any sensor that could give you both range and speed of the target, which are absolutely needed for lead computations. Ever wondered why even the most advanced tanks in the world (Leopard 2, Abrams, T-90) still only use rangefinders + "Mk I Eyeball" for the most part? Also, a LCOS can't do magic: converenge of different weapons would still be a major headache.
