Celestia uses 100% of my CPU?

[M16]

100% cpu usage, is this normal? I want to know from other users if this is only me or it happens to others?

I’m using Celestia 1.3.1
With an Ati9000 pro 128mb @1280x1024
P4 2.4GHz
WinXP SP1

This is the only program that causes this, I’m a 3D modeler and I use numerous heavy 3D programs, and none of them does this. Is there a known issue that I missed somewhere, or I’m just unlucky, and would be better to redownload and reinstall again?

Some other suggestions

Other than that, I still find this program well done, and very informative, great work!

Howdy M16,

Probably not the answer you'd like to hear, but this is normal. There is no "CPU throttle setting" in Celestia. Sure wish someone would come up with a patch to allow setting CPU usage, or frame rate, in some way.

Celestia is a real-time simulation program calculating the position of and displaying 100,000+ objects (planets, moons, spacecraft, stars, etc.), 100% of the time it is running. The same thing will happen with any other real-time simulation program that does not allow user-defined CPU usage -- it simply uses every CPU cycle that's available.

Cheers,

Eh! Howdy to you to Don
Wow! No throttle setting, lots of 0’s and 1’s going thru the CPU eh!
Anyway! I will use it briefly but often, a find that the CPU temperature rises a bit when I’m using Celestia for a long period of time. Sad, but still worth it!

The only way to get Celestia to use less than 100% of the CPU is to have a hardware configuration that's powerful enough for Celestia to be able to completely redraw its window in less time than the screen refresh rate: a framerate > 60fps.

Celestia will display its framerate if you type a "`"

I've sometimes managed to do this on my system at work, but only for very simple viewpoints: looking at Mars from more than 60,000 km, for example.

System configuration:
512MB 2.4MHz P4, Win XP Pro, sp1
128MB FX5200, drivers v56.72
