mfc, opengl & performance: inconsistent?

[lukla]

hello!
i have a problem concerning opengl and mfc.
at the moment i'm doing a degree dissertation for
school leaving examination in opengl,
but now i'm fraught with problems:

it's a simulation of the assembly of a
printed board by a roboter.

so the problem is:

when starting the process cpu usage is about 30% (PIII 1.2GHz),
but after about 2 minutes of assembling usage increases
to 100% and the glwindow jerks, later on the app crashes.

framerate also decreases.

so the glbox is in form of a picturebox in a mfc dialog.

who knows the problem and what to do?

thanks,
luk

You are probably having some form of resource leak in your program. These things are unfortunately very hard to track down. You should check your code if every object/handle you're allocating is being properly disposed of.
