Does anybody here have any idea, why I cant see any ringed planets without the planets textures going dodgy(black triangles all over them) and it slows down ALOT.

My video card is Ati Radeon 9200, I have 512Mb DDR, 128Mb screen memory(or something like it, I dont know what it is in english.) and my processor is 2,08GHz(2082MHz).

I've tried to switch the rendering type to Basic, Multitexture and Vertex Program, but it still doesnt show ringed planets nor their rings correctly.

My video card can also read 2k graphics, and the rings and their textures are a filetype my card supports and are 1k.

I'm really confused what could be wrong with it.

Help greatly appreciated.

Picture of Saturn&Rings with vertex program:


On Multitexture and Basic its otherwise the same but the saturn just turns to a dark green melon with brown stripes and slows down even more.

This also happens with Uranus and Jupiter.

It seems to me that the graphics drivers may be woefully out of date. Your copy of Celestia shows
Version: 1.3.3604 WinXP Release
The ATI Web site claims to be providing display driver version 6.14.10.6546

I don't have an ATI card, though, so I'm not sure if the two numbers correspond to the same information.

ATI's drivers for WinXP are available at https://support.ati.com/ics/support/def ... deptID=894

Yeah my drivers havent been updated even once since '03 I got this computer

Well now I upgraded, and got the brand new Catalyst 5.5 driver pack working good. The ringed planets show up properly and it even renders normal planets 100 times better than before! IE. Mercurys craters shadows look very realistic.

Thanks for the link, selden. Now I can make my Ocean of Stars systems and other things better when I can have rings and even see them myself.

That Saturn pic is scary...
