Hi, i display my model (about 10000 triangles) without texturing and i have about 200 fps with the per fragment lighting. But when i execute the texturing code i just have about 7 or 10 fps... these are code parts :
int main(int argc, char *argv[])
{
	myLoader= new loader3ds() ;
		
	glutInit (&argc, argv) ;
	glutInitDisplayMode (GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH) ;
	glutInitWindowSize (640, 640) ;
	glutInitWindowPosition (250,250) ;
	glutCreateWindow (argv [0]) ;
	glewInit();

	glEnable( GL_DEPTH_TEST );
	glClearColor(0, 0, 1, 0);
	
	myLoader->lighting() ;
	myLoader->loadTextures() ;
	
	glutReshapeFunc (reshape) ;
	glutKeyboardFunc (keyboard) ;
	glutDisplayFunc (display) ;
	glutIdleFunc(display);


	loadShader *myShaderLoader = new loadShader("vertexShader.vert", "fragmentShader.frag");

	glutMainLoop () ;
	return 0 ;
}



void loader3ds::loadTextures ()
{
	glGenTextures (myLoader->getCounterObj()+1, texname);	
	int i ;
	for(i=0 ; i <=/*1*/ myLoader->getCounterObj() ; i++)
	{
		if(strlen(myLoader->myObjects[i].textureNames) > 0)
		{ 
			SDL_Surface *texture=IMG_Load(myLoader->myObjects[i].textureNames/*"wood_b.jpg"*//*"bois.bmp""eyeball.tif"*//*"eyeball.JPG"*//*myLoader->myObjects[i].textureNames*//*"wood_b.TGA""herbe.bmp"*/);
			cout<<"texture "<<texture<<" nomTex "<<myLoader->myObjects[i].textureNames<<endl ;//gérer le compteur d'objets dans 0xa300
			
			glBindTexture (GL_TEXTURE_2D, texname[i]) ;
	
			glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_BASE_LEVEL, 0);
			glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MAX_LEVEL, 0);
			glTexParameteri (GL_TEXTURE_2D,	GL_TEXTURE_MAG_FILTER,GL_LINEAR);
			glTexParameteri (GL_TEXTURE_2D,	GL_TEXTURE_MIN_FILTER,GL_LINEAR);
	
			glTexImage2D(GL_TEXTURE_2D, 0, 3, texture->w, texture->h,
					0, GL_RGB, GL_UNSIGNED_BYTE, texture->pixels);
	
	          }
	}
        //delete texture
	glEnable(GL_TEXTURE_2D) ;
}
