Framerate low, when window big

[Andi96943]

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) :confused:

Is there anything to fix it?

thanx

I suppose it's a software renderer. Post some spec... OS, CPU, graphics card, driver, driver ver...

... 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 :cool: )

now only those programs are Very slow, where stencil calc are there or reflection features
:(

is this normal?

thank you
