Celestia Forums

The newer version graticule-cmod-150 slows my computer down to a crawl when I am in OpenGL 2.0 mode. In basic, multi and GL there is no issue.

To test whether it was definitely the graticules, I loaded a fresh copy of Celestia on my system. I tested other addons in GL2 and found that only the graticules had this slow down effect.

Can others duplicate this? I fear that it might be time for a new video card...

A guess would be that openGL Lines are being drawn using software routines (which surprises me).

Did you try another Addon that uses OpenGL Lines?
Cham's Magnetic Earth would be a good example.

Will try.
