So I'm working with OpenGL, and DevIL to load some JPEG into my program, and I've had some trouble, I've isolated the program in a simple sample program (uploaded), the program is, that when I load the standard file, that came with the guide ("Geeks3D.jpg") it loades instantly and runs with a CPU usage of 0%, however if I load my own file, I'm getting like a heavy lag, before it loads, and then 100% CPU usage.. My question is, WHY!?
I've uploaded the source code, to change between using: "Geeks3D.jpg" and "Test.jpg", simply comment out "#define _PICTUREONE", in "cdemo.cpp".
The project is made in DevC++, and if you're wanting to use help me out, and only got VC laying around, simply compile with;
freeglut (glut will do) glu32 opengl32 winmm gdi32 devil ilut ilu
Any help, or idea is welcome, kinda hoping to get this to work soon! :)
