The Maximum amount of triangles
How many triangles are used in your program before it comes to a extreme slowdown (below 8 fps). Is rendering 100.000 triangles in one screen and having extreme slowdowns logical ?
And anybody knows how to set OGL so that it does not display hidden objects. (Objects that is off screen), or it must be done manually ?
well, you touched a BIG issue:
HOW FAST IS MY MACHINE ??!!??
I can tell you that it depends on many parameters, but 100,000 triangles is a lot, so it might be ok to have a slowdown...
On the other topic, removing hidden objets has to be done manually. Check if the object is in the viewing area, and if not, don''t render it.
It will save you a lot of power!! and speed!!
good luck

Of course turning on backface culling never hurts. well unless ure lazy and havent defined ure tirangle verteces in a clock wise direction

IF you''re also using lighting, texturing or any other 3D features, 100,000 visible triangles is a bit extreme for real-time use on most machines right now. I''d aim for more like 20-50,000 triangles at most, and that''s for a relatively high-end gaming machine.
Depends what sort of triangles they are. A GeForce2 can do 20million+ per second if they are simple.

u have to do this yourself. its called culling.
heres what u should be aiming for roughly
1024x768x16 (multitextured and lit)
tnt1,voodoo2 80,000 tris a sec
voodoo3,tnt2 150,000 tris a sec
voodoo5 500,000 tris a sec
geforce/radeon 1-2 million a sec
