Dealing with Windows 7?

[danielj]

I thought it was a problem with Vista,but I am having the same problem with Windows 7.My system specs is average,but OK.A Core2DuoE7200,4 GB RAM and GTS 250.But I have severe problems with some games and also with Celestia.In Celestia is when I?m panning in and out;the frame rate can get to 14 fps or less.Although it is only happening with very high resolution texture maps,they are VT and shouldn?t behave like that.I wonder if I have to overclock my CPU or the problem are with the processes behind,offscreen.I disable Steam and also put a silence mode in Norton Antivirus,but it looks like it is not enough...
I put everything visible:nebulae,clusters and galaxies.
The main problem are with Mars MDM21 texture map,Earth BMNG and Io volcanoes.
Can anyone give me a help?

Try switching render mode through CTRL+V maybe that helps.
Also please download the most recent drivers for your graphics card from your vendor or Nvidia, NOT from Microsoft.

[danielj]

I have the most recent driver 258.96,that is is not beta.

You can use Win7's Task Manager to find out if anything else is using CPU or memory. On the Performance tab, you can select the Resource Monitor to see even more details. With everything enabled, Celestia does have to do a lot of work. Having many background objects like Stars and DSC objects slows things quite a bit since Celestia has to inspect each one to decide which ones are visible and which are hidden behind a planet. I suggest disabling the VTs, just to see if that improves performance. What things are "supposed" to do is not always what they actually do. Unfortunately, Celestia is single threaded, so it can't take advantage of additional cores.

let disable it as much as possible. Note that some are necessary for the net (fews) some not (lots).

In Celestia is when I?m panning in and out;the frame rate can get to 14 fps or less.Although it is only happening with very high resolution texture maps,they are VT and shouldn?t behave like that.

This really sounds like the slowdown comes from loading the VT tiles, so the problem could be a slow hard drive, or memory management (does Celestia properly unload unneeded textures meanwhile?).

[danielj]

I have 3 HDD,not in RAID because my motherboard don?t support it.I have 2 SATA II HDD (500 and 320 GB) AND 1 SATA HD (160 GB).All of them are 7200 rpm.Could be this?Maybe most of the Celestia users have SCSI HDDs.

[selden]

@steffens,

Celestia never unloads anything, so it grows until it crashes -- which is at a maximum of 2GB. (It's a 32bit application.)

@daniel,

No modern consumer-grade computers come with SCSI any more: they all use SATA. You have to pay lots of extra money to get a SCSI host adaptor, so it's usually used only for workstation class computers and servers which need 15K RPM disks.

Please watch your disk activity lights to see if they are blinking a lot while you see the slowdown. That would be an indication that the loading of VT textures is the problem.

You might consider getting a RAM disk driver, which uses part of your computer's RAM to act as a disk drive. That's the fastest kind of disk you can have.

[danielj]

You mean a pen drive?

[Fenerit]

Danielj, can you tell how many RAM is free on your system before you start Celestia?

[selden]

You mean a pen drive?

No. The USB bus is very slow compared to the internal disk's SATA connection.

I mean a simulated disk which actually is in your RAM.
I don't use one, but it looks like DataRam's RAMdisk is one of the better ones. It's free because they want to sell you more RAM

[danielj]

Before I start Celestia,only using internet and with Norton,BOINC and Steam in the background,I have aproximatedely 1.5 GB used and 2.5 GB free.It?s my guess,but I can verify for sure.

[danielj]

But only 4 GB is free.More than that,you have to register and pay for it.I don?t think an extra 4 GB will be enough...

I supposing you have the icon of the Nvidia control panel on the systray: what value is set for the antialiasing? 1x 2x 4x 8x 16x... or none (application controlled).

[danielj]

None (aplication controlled)

[Fenerit]

daniel, if you have the possibility, do assemble another, less powerfull, computer to surf on the net and leave your most performant for the rest. No antivirus, no redundant services and so on and the computer surely will goes best.

[danielj]

It wasn?t necessary.The problem was that I have a single GPU,and I put the option "mixed display perfomance".I enabled single display perfomance,put the image quality to perfomance and with only galaxies enabled from the DSOs,I have 50-75 fps in 8k 3dtextures of Valle Marineris on Mars2 and above 25 fps in Io?s volcanoes animation.
