Another thing simulated reality offers is afterlife, in any number of forms. If it turns out there is one (or more), I'll try to remember to attribute that to being in a sim.
Out of my simple head, I'm a bit uncertain that nothing can past the speed of light. Maybe there's something else traveling at higher speed but we're unable to detect it.
This can be related to the thing you mention about "in simulated reality they could turn up the clock speed". Just rambling thoughts
