I’ve seen it a long time ago, and if I remember well, they have to prevent the simulation people to build a simulation, otherwise the hardware will not be able to keep up. And big part of the plot, the scientists can load in the simulation.

There is a tv film, i don’t know the title, related about this topic.

The plot was :

a group of scientists made a living simulation, and go in the simulation to operate fixes and prevent making simulation. On day, one the scientific was killed, and left a message in the simulation for their coworkers. The message was : “take a road and follow no direction”, a guy in the simulation followed the instruction and discovered that he was in a simulation, but the message were for the scientists who are in a simulation too.

If someone can find the movie, it could be great.
