hi,
i’ve written a small programm with GLUT, where you can see a cube and its shadow on a plane.
windowsize is standart 100 x 100
when I make the window bigger (e.g. 800x600) the framerate is VERY low.(2 - 10 fps) 
Is there anything to fix it?
thanx
Ak
I suppose it’s a software renderer. Post some spec… OS, CPU, graphics card, driver, driver ver…
yooyo
… desktop color depth and your glutInitDisplayMode call, too.
ok, I fixed the problem I think. I installed the actual nvidia graphic driver. now everything is too fast(but this is no problem 
)
now only those programs are Very slow, where stencil calc are there or reflection features
is this normal?
thank you
