flight simulator use a server - client architecture in order to be able to set a multiview display. not sure if it's native , or a feature of a 3rd party plugin..
You can so have a 20 computer network , each one managing 1 different view. computer #2 could have 5fps, where the 19th other have 30fps.
you ask me to give you a way to do that in a viable way for BS or FC , i can't. but I KNOW some guy KNOW how do it .
SWAT4 on PC use a mini windows head camera for teammate view. this camera doesn't eat more than 10% of framerate. right it's not the same game, neither requirement, but i'm sure their way is more efficient than how ED did that.
and GPU wise, i'm pretty sure lockon doesn't push my card in its limit. texture wise , geometry wise, and shader wise ... my cpu is the bottleneck , or should i say the game code ?
performance isn't all about harware. software is involve too :smilewink:
intel , or few developper conference talk a lot about this rendering technique these time , mainly because multicore cpu are now mainstream.
ps: Fighter ops might be modularised. they talked about not throw our old computer ;)
