Limiting the ability to have titans does not fix the FPS issues that are caused when a Titan enters your sector, assuming you get any lag at all.
No - it does better. It
prevents the kind of lag with which we are all concerned from occurring. Schine already has continually optimized to accommodate the rampant small-man syndrome Starmade seems to engender, and in response the scale of building has just increased.
Titan is a meaninglessly subjective term, and the so-called titans players field today are bigger than the titans from a year before. To hope that speculative "future optimizations" will somehow 'solve' players' ability to lag servers seems fruitless, when past optimizations have only spurred scale growth upward until it again scrapes the same inevitable physical performance cap of what a computer can perform. Optimization would be great, but even if Schine somehow halves the processor loads and insists that all players run on 32GB of RAM, the net result (based on observing past optimizations) will just be 50M mass titans lagging servers instead of 500K mass titans doing it.
The point at which the game breaks servers is irrelevant. The important issue that the game
does crash servers, crash clients, and and lag out networks because more needs to be done to prevent players from performing actions in game that are known to cause such performance instability. At some point, the laws of physics and human nature must be acknowledged - no one's rig has infinite capability, and people will always push boundaries.
Without strong checks and balances on scale, without well-designed resistance factors to
prevent incidences of game-breaking level lag, this game will always be unstable.
