Standing on Earth's surface

On my old computer which had 810 chipset driver I would have
problems when on the surface of Earth or Mars. It was jumping
up and down like a wild stallion. Now on my new computer ,
Win xp pro , nvidia 6800 card the exact same thing happens.
What's up with that? Something i can fix or not? I am not sure
if I should put this in the bug section or not.

Since you did not care to make any comments about the controls you used, I suppose you are aware of the key commands to land on any object's surface and move in parallel to it with the cursor keys...I find the movements close to the surface very well controllable and smooth (Linux). One should however always stay at least at about 20 meters of altitude above ground.

What you should be doing to land on a surface is getting the place on the planet you want to land on centred in the view (press Ctrl-K to show markers, if necessary - that's where you'll be landing), then pressing Ctrl-G to go to the surface, then pressing Ctrl-F to go into alt-azimuth mode which allows you to look around while on the surface. Is that what you're doing?

Fridger, I know the controls. Mine stops bucking wildly at about 60 m. I wanted to go to the surface or much closer within a few meters.
Dr. Evil G I use ctrl-k and ctrl-f I was just wondering why it bucks
near or on the surface that's all. I just have to get started reading Celestia
info again so i can change textures, etc. I forgot a lot. It's been about a year and a half since I was last on.

what do you mean by 'bucking wildly' and 'jumping up and down'? Like, you're happily on the surface and then suddenly for no reason your view starts shifting up and down rapidly? If so, I can't say I've ever seen that happen before myself so I'm not sure what could be causing that...

He means that the horizon and other borders start flickering and changing position.
It happens on my system after landing on the Earth with a Ctrl-G when I reduce the distance to relatively small values, less than 2 meters.
I think it's related to Celestia's clipping plane problems. The symptoms (distance from object and severity of the bug) are different on different graphics cards.

256MB 500MHz P3, WinXP Pro SP2

Oh, now I see what he means... yeah I could reproduce that. Just get to about 2 m from the surface and it flickers up and down. I'd agree that it's probably a clipping issue.

on my system it's more like 60m before it is completely calm
