Speaking of dual-monitor support, that would be kind of hard to do on video cards that don't like to render OpenGL to both screens (which includes many consumer-level cards today). Thus, this feature would currently be limited to cards such as 3DLabs Wildcat, etc. However, Matrox's new "Parhelia" ca...

Without them you could run something like 3 times slower than normal !

I have the VIA 4in1s version 4.38. Are the new betas worth upgrading to from that?

I'm sorry that I have no idea how to help you, because I have never had any problems with Celestia (aside from general sluggishness) on my 800MHz Duron running Windows XP Pro with a Radeon VE.

Your suggestions sound great to me! I'd also like to see some enhancements in the performance of Celestia - It has trouble running smoothly on a Radeon VE and 800mhz processor machine (which I admit is not the best on the planet, but if it can run UT well, it should be able to do Celestia, too).

What kind of video card do you have paired with that Athlon XP?

Well, the 100% processor usage isn't really the problem. The problem is that when moving around in the solar system (and elsewhere), the graphics stutter. I don't really know how else to describe it, but only to say that it's not smooth. Thus I was trying to figure out which component would be more ...

Hmm, even when I pause the time, it still sticks at 99% usage. Maybe it's time for a new gfx card after all

That's odd. I have an older P3-500, also with 256mb RAM; but a 64mb GeForce card. Celestia runs smooth as silk - usually at 1024 x 768 x 32. I'm just going by the visual; as I've never checked the frame rate. Do you have anything running in the background? No, there are not any other normal priorit...

Celestia 1.2.4 is running ok on my 800MHz AMD Duron machine with 256MB of RAM and an ATI Radeon VE (32 MB RAM). However, whether it runs in a reasonably sized window, or an 800x600x16bit or 32bit resolution full-screen, it always seems to be running at a very low frame rate (i'm guessing it averages...

Thank you for the suggestion. I'm downloading those right now, and will try them out soon.
