performance with nview dual display

[LaderOne]

Hi:

I'm used to work with 2 big CRTs all the time; I noticed that Celestia is able to run in an extended desktop covering both monitors, but the performance is very poor, and even though the video is handled by a single FX5900 card, the advanced render modes that are able to display the rings shadows over saturn are disabled. May I missing some particular setting I have to tweak to correct this? there is something like a command line to improve performance with extended desktops?
Thanks for the help and sorry if this topic has been covered before but I'm not coming to the forum with the frequency I used to before.

The standard N-view settings should work fine.

I have run celestia on a number of dual monitor systems with the following cards.
mx400, mx440, FX5200 and FX5650
With all of them there is a performance hit running on 2 monitors as opposed but it is not detremental. With the FX cards the ring shadows remain.

If you have not already done so, try the latest nvidia drivers.
Also try not checking the 'extend my desktop to this monitor' checkbox. Instead use the horizontal spanned option which is with the clone setting. This way you can select full screen resolutions like 2560x1024 from within Celestia.

Finally make sure both monitors are plugged into the FX5900 and that you are not using an onboard or second video card. (sorry if im telling you to suck eggs here)

hope this helps.

Marc.

Hi Marc:
Thanks for your response. The case is that I'm using the latest nvidia drivers (53.04), and both monitors are conected to the same card. The thing I probably forgot to said and may be important is that I use windows 98 second edition as OS. I know it maybe old, but it works fine for me. I was browsing around all the options there and I couldn't find any clone settings like the horizontal spanned you mention. Please tell me if this is not available for my OS or there is something I'm missing. Thanks a lot!

I find out reading the nview documentation that the mode you mentioned is not available for windows 9x. Well, there goes my first strong reason to move to XP. Hate it, but I guess I have to give it another chance... Thanks for your help anyways!
