STARRY NIGHT PRO 6 DISABLE OPENGL SOFTWARE

This is a problem that has been brought up here before as well as other astronomy software forums and groups. As Andre mentioned, use SN's customer support. If you were upgrading from XP, this may not be so surprising since Win7 graphics APIs and their processing are organized in a much different fashion and graphics intensive programs that ran under XP may or may not work under Win7, depending upon how the API's are used (which is one reason for the legacy compatibility modes).

STARRY NIGHT PRO 6 DISABLE OPENGL DRIVER

If SNP 6 ran under Windows on the same machine and same graphics card prior to the upgrade, then it may not really be the card itself, but the driver for the card or the OpenGL driver under Win7, which may be solvable. And if its a registred version, I strongly suggest you to write to customer support, they will help you. I find myself very sad SN doesn`t use Direct X instead of OpenGL. Just make sure your video card can do OpenGL.

STARRY NIGHT PRO 6 DISABLE OPENGL WINDOWS 7

Ok, if its an OpenGL issue, that is not related to Windows 7 and SN Pro but your video card. If you have a graphics card with less than 32 MB of RAM, you might want to select Use half size textures.It seems you have found the right section of CN. The OpenGL Performance Options section allows you to optimize and speed up OpenGL performance depending on the video card you have. Selecting Disable OpenGL does just that and graphics are rendered in non- OpenGL mode. When Use Starry Night Settings is selected, Starry Night will use the preferences set in the Preferences Dialog box (File-Preferences menu (Windows) or the Starry Night menu (Macintosh), then choose General from the drop box in the upper left corner of the Preferences dialog box). In addition this section lets you toggle between using the settings set in Starry Night or the option to disable OpenGL. It also provides you with the OpenGL version supported. The OpenGL Hardware Info section displays useful information about the make and model of your video card. The Starry Night Display Settings window is partitioned in two sections. The Video Test application is a tool that displays information about your Starry Night OpenGL Settings and allows you to tweak a number of performance options. What is the Video Test application and what does it do? (Windows only) Use half size textures: Checking this option will save on video graphics memory and should improve performance on slower computers or video cards with less than 32 MB of memory.įorce texture cache size: Specifies the amount of memory cached by your video card.ĥ. On the PC, if your card supports it, turning this feature on can have a speed improvement in how fast stars are drawn if your card doesn't support it, it can result in slow stars or blocky stars. If you are experiencing the 'blocky star' effect on the Mac you can try turning this feature off.

By default polygon smoothed stars on the PC are turned off and on the Mac they are turned on. However, depending on your video card this can cause labels to flicker.ĭraw stars using polygon smoothing: Some video cards have trouble doing what's called polygon smoothing and this can cause 'blocky stars'. Use sub-pixel accuracy when plotting labels: Sub-pixel accuracy gives labels a smooth feel as they move on the screen. If for some reason, you have an OpenGL graphics card but do not wish to run the OpenGL version of Starry Night, uncheck this box. Use OpenGL: Checking this option will enable OpenGL if your video card supports it. The OpenGL dialog box allows you to select a number of options.

OpenGL offers improved graphics on computers whose video hardware supports it. What do the various OpenGL options in the Preferences window mean?
