I was been ironic. The problem with GSG like I:R is the using of scripts. Everything is done by your processor, EVE and other online game is a REQ and RES game, your computer just show you what is happening in the server he doesn't make any calculation.
I:R, Stellaris and CK3 they try to simulate with number,programing logic what is happening and gonna happen. Now with a 3D battle this gonna push much more of your Processor and Video Card, for me I:R has more battles than my game in Stellaris. And using the picture that @IsaacCAT show to us, seems to me a kind of Total War that would increasing even more the requirements for the game.
The difference of TW to GSG is just that is turn-based and has open-battle.
Ah ok, it was late sarcasm meter was on charge.
