Celestia Forums

I'm a new member at shatters.net but using Celestia already for about 3 months.
I got a problem: the Performance is very bad!
my machine:
AthlonXP 2000+
Geforce4 Ti 4600
512 MB DDRRAM
WinXP with Detonator 40.72 (works perfectly)

although I have the hardware to expect at least smooth 25fps at 1024x768 I just got 6-10 fps at Celestia 1.2.4, it doesn't matter how low I choose the resolution...
Did I make sth. wrong or am I too stupid to switch on or off some options?
All other games and benchmarks are working great (e.g. 3DMark2001 SE: 10700 3d-marks)
Is celestia that "hardware-hungry"? Anyone who can help me???

Hugh,

Have you verified that "hardware acceleration" is enabled?

I have a much slower system and it usually runs 20-30fps
(500MHz P3, Ti4200, 2xAGP, same software as you)

Disabling Rendering of Galaxies and Stars usually
speeds things up.

I hope this helps a little.

You can find if hardware acceleration is enabled by selecting the OpenGL Info option in the Help menu. If it's enabled, you should see a long list of extensions displayed . . . Most games use Direct3D instead of OpenGL for rendering, so you're problem is likely that you don't have OpenGL drivers installed. Try downloading the latest driver set from http://www.nvidia.com.

I've checked things and OpenGL is activated with all extensions (also works in several games).
The only thing I can imagine that could lead to a performace-loss is that I have installed several plug-ins like more galaxies, many asteroids in the solar-system and space-crafts like Voyager 1+2.
When I leave the solar-system and move to another star the fps go up to 28-30 but when I choose another Star which has planetary companions the fps go straight down to 13-15 fps again.

Until a few weeks ago I used Win98 as operating-system and the performance was nearly the same with DetonatorXP 30.82, DirectX 8.1.

I don't know where the problem is. Maybe the fps are displayed wrong somehow. The rendering seems to be more smooth than 6 fps but not as smooth as 30 fps in games...

Aha... if you have the loadsa asteroids add-on, don't expect it to run at all well. Disable it unless you really want to tax your system...

Good hint, Sum0!!!
I've disabled the asteroid-plug-in and now the fps are constantly between 20 and 30, even with 4x anti-aliasing and 8x anisotropic-filtering the fps are not below 15!!!
When I also disable galaxy-rendering (I have installed a plug-in that includes over 100 galaxies) I even get 75 fps!!!
Therefore the problem is solved.
Thank u all so far for helping me.

You might want to try getting the latest prerelease of Celestia. t00fri added some code for galaxy culling that should help the frame rate when galaxies are turned on. There are a lot of other new features too . . . get it here: http://www.shatters.net/celestia/files/celestia-win32-1.2.5pre7.exe
