Here comes what OpenGL info show in Celestia:

You're missing the extensions ARB_vertex_shader, ARB_fragment_shader, and ARB_shading_language_100, which are are required for the OpenGL 2.0 path. But since you have recent drivers, I'm confused as to why these extensions are missing. Does anyone else with a GeForce FX 5200 have the OpenGL 2.0 path working?

Guys,

Yes, I have the FX 5200, and the OpenGL 2.0 render paths are there (after judicious use of CTRL-V, since Celestia doesn't retain this setting on restart).

I'm using the 61.76 drivers (possibly because I run W98se). It all seems to work well (properly lit planets with secondary lighting, though I did have to turn Alpha Centauri B into an A0 to see it).

I've noted some stability problems, but this may be due to visiting some high-detail systems. I'll detail those issues later.

Also, the latest Nvidia drivers do have an adverse effect on other programs (frame rate slowdown etc), and of course OpenGL requires me to use a single monitor.

Other than that, its all fine.

I must work out how I can upgrade my video card without the wife skinning me for buying two new ones in the space of 3 months

Cheers,

Cormoran

I'll second what Cormoran has just said, although I have 61.77 drivers and run Windows XP. I've just discovered I'm able to use the Open GL 2.0 render path, much to my suprise, even though I only have 1.5.

I seem to be getting the 'proper' lighting and shadow effects, but the cost is a reduction in frame rate compared to the OGL VP/NC render path I normally use. Also the haze effects seem to be missing.

This is my OGL info;

Chris,

I have no problems using the new Render path on my XP system at work, which has a 5200.

Cormoran (and praesepe)

How did you install the latest drivers?

In particular:

Did you update DirectX before or after installing your current drivers? DirectX 9 replaces the most recent Nvidia drivers with old drivers from Microsoft.

Did you use Control Panel / Add-Remove Programs / Remove Nvidia Drivers / Reboot to delete the old ones first or did you install the new drivers on top of the old ones?

Did you make sure your anti-virus software was disabled before you did the update? (and, of course, reenable it afterward!)

If you leave out either of these prerequisites, too often the old drivers will seem to install, won't generate any error messages, but won't actually replace the old driver libraries because they're still in use or are protected against modification.

When Forceware 61.76 (win98) or 61.77 (winXP) are installed properly, Celestia will report that you have OpenGL v1.5.1

When Forceware 66.81 (winXP, beta) is installed properly, Celestia will report that you have OpenGL v1.5.2

Selden,

My Celestia OpenGL facility reports 1.5.1. The configuration posted wasn't mine.

Anyways, When I get a second or two I will reinstall my Nvidia drivers properly (then go thru all the crud I have to so OpenGL will work consistently).

I know for a fact I am using the most recent OpenGL drivers I have found (61.76), since I compared file sizes prior to install.

However, I will do as you suggest, and report back....

At least with the drivers I know have, my worlds around Alpha Centauri have nice double lighting.... must try a ring system

Cheers,

Cormoran

Cormoran,

Sorry: I didn't scroll back far enough to get the right name when responding

My response actually was meant for praesepe, or anyone else with a similar problem.

First of all, thank you for all of your responses. I finally solved my problem and found a workaround to fix the problem: I uninstalled the Nvidia drivers and cleaned any reference found in the registry and then rebooted and made a clean install of the new drivers (61.77) and voil?, the new render path was there

I've been making a couple of tests with the new light system using my old gliese system texture that have night side glow. For the occasion I used a quadruple star system and applied some rings to see all eye candy features that this new OGL2.0 libraries can offer. As usual, here come the screenies:

The original system:


Quadruple system:


Quadruple system with other star positions:


P.S.: I love this last one. Note that there is only partial night side glowing due to the light coming from a star just to the right of the system...

Nice to see you've got the OGL 2.0 render path option available Praesepe.

Have you tried astrojockel's multiple Sol settings on our solar system yet ?

Are there some new nvidea drivers available ?

Yes, but only for Win2000 & XP. On the page
http://www.nvidia.com/content/drivers/drivers.asp
select the link "Beta Drivers" which is just above the form for selecting the official drivers. Supposedly the beta drivers are only WHQL certified for GF 6nnn cards but they seem to work fine for older cards, too.
