The DOGULEAN Planetarium 3.3

Requirements and Recommendations

Basic Requirements

If the Planetarium Seems to be Eating Up Too Many of Your Machine's Cycles

Depending on the zoom and time rate you have set, the Planetarium may update the screen as often as 25 times per second. If that doesn't leave your machine enough cycles to do other things, then maybe you shouldn't run the Planetarium on that machine.

If you still want to run the Planetarium on that machine, try reloading the page. That will reduce zoom to at most 5 and the time rate to 1, so that the refresh rate will be at most once per second. After that, if your machine is still too slow, don't use it to run the Planetarium.

If your machine's performance is ok after reloading, then, in future, don't zoom in so much or set the clock rate so high. Your device is probably marginal for using the Planetarium.
