If you supply an implementation of Direct X for all non-M$ platforms that Stellarium supports it might be worth doing.

It's ATI's fault they don't have a proper OpenGL implementation for all platforms.

It just means that Stellarium is not suited for general consumers and that is fine, we dont all have the luxury of understanding the finer detail of software. I bought the Laptop before I even knew about Stellarium.

Anyway there are other programs out there, I would have liked to try Stellarium but I know that is not going to be possible until I get another computer.

More likely the problem is that Microsoft have made Direct X so that software manufactures have to hand over the money to have access to Direct X don't forget Stellarium is provided free. In my opinion something like Direct X should be able to be available for software makers if Microsoft want their Direct X to be the standard. Or have ATI make drivers for OPENGL which is available to all for free. So I don't see how we can blame Stellarium for the greed of others.

Just for those with "resource" constraints, you can force the frame rate down so that it doesnt hog your cpu. I have mine set a 5 fps and you cannot notice the degradation in screen performance. If i dont set, it tries to give me 40fps.

You edit the config file with a text editor and look for the maximum frame rate entry.

I set this, but it doesn't seem to believe me.

Stellarium uses OpenGL because it is a requirement of the GPL Licence. Direct X is the Proprietory garaphics accelerated owned by MS. It can never be used by stellarium because they don't distribute source code.

ATI has been quite tardy in distributing drivers for their video system that keep up with the development of OpenGL but the situation is improving and there are drivers available now for most systems. Stellarium has also included some work arounds that let it display video quite well on chipset drivers that are not up to date.

Version 0.10.3 which is about to be released has a greatly improved video card compatability.

However Stellarium may not be everyone's "cup of tea" which is quite a pity because it has a marvelous 3D display in real time and it will always be free. Remember the old saying "never look a gift horse in the mouth"

Trevor has a later version of stellarium than the distributed version 0.10.2. 0.10.2 had some bugs that were quickly rectified and one of them I believe was the frame rate adjuster not working correctly.

The patch I made for 0.10.2 to make the 0.10.2 version a lot better is still available from www.iceinspace.com.au/uploads/4747.zip (I think)
