Your latest and greatest is data from MRO. The software from USGS called ISIS and another called GDAL is what I used in the past. MEX is another good data source.

This was posted in error. I was looking at a different folder.

It will be a cold day in hell.

Also: I can play Witcher 3 with full graphics, having no issues, but Celestia 1.7 Qt destroys my GPU? :think: OpenGL Checker can reach 50%-60% of GPU resources and it shows that the graphic card has excellent results in OpenGL. I don't think it is a GPU resource or graphic card issue on the hardwar...

The installer I uploaded last year is still available on page one of this topic]. Did you try that recently?

If he already has one it may be failing. So my PC's power supply is failing at Celestia Qt, but it is not failing at Celestia win32? Not likely. Qt is slow for many others, so there must be a reason. Maybe more cpu resources. Gpu resources, whatever. Anyhow the system at full load should not exceed...

Selden, I was not sure what John71 meant by 4 x 3.2 ghz. Does he have a 3.2 with 4 cores or a motherboard that supports 4 processors. If the latter, I would think he would need at least a 1000 w power supply in good condition. If he already has one it may be failing.

I found a setting in windows you may want to try. I'm not sure how Windows 10 did it but it must be similar. I have Windows 11. I was able to go to Settings/Display/Graphics and there was a list of apps I have the option to change the settings. Celestia was not listed. But I was able to browse for C...

I heard about some talk here that qt5 is slow, but my system is not affected with qt5 running Windows or Linux. Both run fine and get good fps. Even with Wine, The vsync setting should be available for your card though Nvidia. When I used to run a desktop and had a Nvidia graphics card, I did have a...

Registry issues could be an issue but only for file associations. When you click on a *.cel or *.celx, it will start either 1.6.2.2 or 1.7. That should have nothing to do with frame rates though. Since 1.6 and 1.7 are using the same registry keys, the last one to get installed is the one that should...

Try using the Shift "~" key to see what is loading at start up and while you travel about. Also you can see 1.6.2.2 and 1.7 are in different folders. If they are, they should have nothing to do with each other except cel, celx, file associations. They should not be using each others dep dl...

When you use windows to uninstall programs, the only files that are deleted are those that were installed. Anything that was added to the installed folder remains. So. As I stated in a previous post, When I uploaded the first installer this month, I forgot to give it a unique GUID. So it would have ...

You don't seem to need a stress test. But when you used the 1.7 installer, did you install it to a new location or on top of another installation? If it was a new location and nothing else was added, I'm out of ideas.

I read about one person who had low frame rates cleaning the card contacts and reinstalling it to get rid of their problem. Also maybe you should take a look at BIOS settings. And as Selden suggested, install and test your card with Furmark. For comparisons sake, my laptop specs are in my signature....

In Celestia: Do you have the hires textures installed? (I don't.) In hardware: What's your screen resolution? 4K, maybe? (Mine's 1080p ) It is a clean install from Cartrite's file, nothing more. It runs in a window at 1080p. I have the latest driver AND I can run almost any modern game with it. I h...

This is version c23206e7 and is for testing the galaxy rendering committed today. I had a slight problem I found. When I first started the win32 version, all the stars were about 5+ pixel squares, the screen was frozen, and Celestia crashed. On all other attempts, the win32 version started with thes...

I modified start.cel to start at about the time of the crashes. The qt version failed to start once but there was no output to show why. The little cursor was bouncing up and down but then it disappeared and nothing. The splash screen never appeared. So I tried running in a terminal. Didn't do it ag...

I booted into windows and ran the demo with the win32 version. During the star tour with the constellations on I got as low as 60 fps. During all the other parts of the demo, I averaged between 150 and 220 fps. I even got as high as 300+ at the end watching the milky way. Not sure why your fps would...

I was able to install the installer I downloaded this morning on my linux system via wine. They take forever to start but once they do both the win32 and qt5 versions run normally. No crashes. The FPS got as low as 3 during the star and constellation parts. During the solar system part the FPS hover...

I know Selden used the installer from last week and didn't have these crashes. At least he didn't mention it. So something must have changed between now and then. The only thing I can think of is a code change to globulars that was committed since. Try turning globulars off. I can't reproduce a cras...
