Low fps in Terrain tutorial

Hi,
I've a question. Is it normal, that in the Terrain tutorial the fps only be 60 - 70?

I mean, this is an very small Terrain, and there are no Objects or game logic.
Is there a better wax to generate a terrain with a heigher performance?

In my opinion there is no Problem with my hardware, the Demo runs with 200 fps.
I'm using Linux Suse 10.2

Thanks Paul

original or self built terrain demo?

eek hmm.. testing... i get.. 150 totally zoomed out with no culling.

it starts around 70... I have an ati 9550 not X not the express pci crap.

i don't like pci express performance from what I have seen (it may be normal for you) and I'm not sure about your card if it doesn't improve a bit when you move around and stuff then yes you have a problem of some sort. how good is that card? mine is older and 256mb... look up reviews on it thats my best guess.

also try rebuilding it just to rule a fucky build out.

than it seems to be normal. When I've zoomed out, I've around 170fps. And while looking to the sky, ~700fps.
Maybe it dosn't use VBO's?

Of course it does not. Irrlicht does not support VBOs, yet.

vertex buffer objects. Store the geometry information on the gfx card instead of sending all data from CPU to GPU each render.
