cleaning up GL

How important is it to delete textures and display lists from the GL after the program finishes? I’m sorta used to the computer doing all the necessary clean-up from programs, but windows is sorta new to me. Should I go and make sure things get tossed when I’m done? If I don’t does it degrade system performance? Or is there a single call to ‘refresh’ the GL?

It depends on the drivers, but it is safest to delete your display lists and textures. If you don’t, then you may be leaking driver/AGP/video memory.

It’s just good programming practice to always clean up, no matter what.

It’s a good habit to get into.
