Celestia Forums

When rotating with the mouse, there is a square in the center of the rendering that flickers. I try to change resolution and refresh rate, but there's no change. I've installed the latest drivers.

BFG GeForce FX 5700 Ultra (128MB)

Athlon XP 3200+ 2.1Ghz
1024 MB RAM
Windows XP Home SP2

Using Celestia 1.4.1

I see no such effect on my system.
Maybe it's related to the point of view.
Or maybe it's just because I don't see flicker easily.

Does it vary with the timerate at which Celestia is running?
Are you running full-screen or windowed?
What's your screen refresh rate?
What's Celestia's fps?

Can you provide a Cel:// url for a viewpoint where you see it?

What kind of display are you using?
What resolution & refresh rate?

Exactly what version of ForceWare?

My ystem:
1GB 3.4GHz P4-550, WinXP Pro SP2
128MB GF6600GT, ForceWare v84.21
1600x1200, 60Hz, Hitachi 812 CRT
Celestia v1.4.1final & from CVS

The flicker does not vary with the timerate that Celestia is running on.

Although it DOES when I change the refresh rate (it flickers faster with a higher refresh rate).

I run it in windowed and fullscreen and at various resolutions; the flicker is there.

I don't know Celestia's fps; don't know how to acccess it.

The flicker seems to be the size about 100x100 pixels, in the center of the window. Everytime I adjust the POV with the mouse, it appears.

I am using a CRT single display.

Forceware Version: 84.21

System:
1GB, 2.1 Ghz Athlon XP 3200+, Windows XP Home SP2
128MB GeForce 5700 Ultra, Forceware 84.21
Monitor: KDS XF-9i

To display Celestia's fps, type a ` (accent grave)

On keyboards that support diacritical marks (as in Europe) you may have to type a space after the `

So far, I haven't seen this kind of flicker.
From the lack of comments, I suspect nobody else has, either.

You don't have any other on-screen windows that happen to be in that location, do you?
(They make no difference on my system.)

Hopefully it isn't a hardware problem in your card.

Do you have any other free 3D application that uses the mouse that you could try? and that I could try, too?
[edit]
It should be an OpenGL app, not DirectX.
Partiview, mentioned below, is OpenGL)

Alternatively, have you tried out Partiview?
It's another free 3D visualization tool

Does it show the same problem on your system? (I've never seen it flicker on mine as you describe.)

I think I've solved the problem. There is another program that uses the mouse. I use ATI's Remote Wonder (for their TV-Wonder cards), which also controls the mouse. I closed that app, and started Celestia, and the flicker wasn't there anymore.

Thanks,
