Thanks for looking into the problem!
I did as you told me - but everything is as slow as before :(
Greetings, Dietrich
PS: I attached the glxinfo output.
Here the changes I made following your instructions:
===
source/blender/windowmanager/intern/wm_draw.c:
---
static int wm_triple_gen_textures(wmWindow *win, wmDrawTriple *triple)
{
GLint maxsize;
int x, y;
/* compute texture sizes */
/*
if(GLEW_ARB_texture_rectangle || GLEW_NV_texture_rectangle ||
GLEW_EXT_texture_rectangle) {
triple->target= GL_TEXTURE_RECTANGLE_ARB;
triple->nx= 1;
triple->ny= 1;
triple->x[0]= win->sizex;
triple->y[0]= win->sizey;
}
else if(GLEW_ARB_texture_non_power_of_two) {
triple->target= GL_TEXTURE_2D;
triple->nx= 1;
triple->ny= 1;
triple->x[0]= win->sizex;
triple->y[0]= win->sizey;
}
else {
*/
triple->target= GL_TEXTURE_2D;
triple->nx= 0;
triple->ny= 0;
split_width(win->sizex, MAX_N_TEX, triple->x, &triple->nx);
split_width(win->sizey, MAX_N_TEX, triple->y, &triple->ny);
/*
}
*/
/* generate texture names */
glGenTextures(triple->nx*triple->ny, triple->bind);
