These people are running max shaders 24/7 in all screenshots. Do you really think that removing the core shaders of unreal and then removing most of the useless parts of unreal which just slows down the game would be worth it just to get people with older computers on the game? Yes, but this is the blockland community we are talking about. They only want better.
there is no justifiable reason to not optimize your game besides severe budget problems. alienating a whole group of users who have subpar computers is objectively stupid for the devs who lose players and the players with bad computers who can't play
It's a reality that lots of gamers are adults and tend to earn a lot less money than teenagers who seemingly have whole luxury cars gifted to them for Christmas. Like I earn 20,000 a year and a good computer could cost like 5% of my salary which is huge especially when I need to save up for future house leases
The short story is that your game should be able to simultaneously look beautiful on high end computers and run at 45+fps on subpar computers. It's perfectly feasible to optimize and streamline all the bottlenecks of CPU usage and especially for a c++ native engine where all instructions take like one millionth of a second. All the shaders should be toggleable and texture quality changeable as well for the user. I'm sure they'll optimize brick rendering but my best suggestion is that one of the devs uses a stuffty computer and tries to benchmark a lot so they can see if they are truly optimizing. Because trying to optimize your game code while running on a supercomputer is dumb since you basically can't measure any improvements outside timers or see if it's applicable
