Hi! Me and some other guys are building a engine("City Engine" that is) and today i''ve build the image/texture part.But the problem is with gluBuild2DMipmaps.Bellow is my computer config and the problem: AMD Palomino 1.4 GeForce4 MMX 64 MB 512 RAM The problem is that the gluBuild2DMipmaps works extremely slow!!!It is called 10 times for 5 seconds!!!I need to call it 10 times for 1 second.Is the function slow or i''m doing something wrong??? What will happend if i use glTexImage2D insted? 10x The PAIN is coming...this summer!!!In cinemas everywhere.

Youre not calling it every frame, are you??

If so, why?

If not, whys it matter that it must be called 10 times in a second?
