Ok ! I have a question about the FrameRate...

I did a few optimizations to the terranin rendering code, and got theese results:

Chopper AND Terrain -> 11-13 FPS
Chopper WITHOUT Terrain -> 14-15 FPS
LowPolyShip WITHOUT Terrain -> 59-60 FPS
LowPolyShip AND Terrain -> 18-19 FPS

I find it a paradox, because the first two test would mean,
that the Terrain engine slows down the game with about 3-4 FPS''s.
15-11=4 right ?
But the second mesaurment, with the low poly model results,
that the terrain engine in fact reduces the spped of the game,
with aprox.: 40-42 FPS-s. How can this be ?

have you disabled vsync on your graphics card?

My graphics card doesn''t have a vSync on-off in it''s control panel.
But if you are reffering to my initialization code,
than it was this: "d3dwindow.SwapEffect = D3DSWAPEFFECT_COPY_VSYNC"
So i guess the answer is NO then...

Why ? Could this be affecting the tests ?
I tried to change it to D3DSWAPEFFECT_FLIP and D3DSWAPEFFECT_Copy, but still no change in the tests.

However i have managed to get up framerate to 20 FPS with the chopper model
So... i guess i''m on the right track

I''l try to fix the sky too, but i don''t know what kind of geometry should i use for the sky...
Any suggestions ?

To get meaningful fps info you need to be running in fullscreen mode with vsync disabled.

Under D3D this means you''ll probably need to specify the D3DPRESENT_INTERVAL_IMMEDIATE flag in the D3DPRESENT_PARAMETERS structure as well as using one of the swap effect parameters that does not force vsync. (it''s been a while since I played with d3d so I''m a bit rusty on this stuff)

I''d recommend starting a thread in the graphics forum if you want to discuss the technical aspects further, or if you prefer I can move this thread.
