Why MyGUI always 30-40 fps On directX platform

Hi
I used 3.02RC1 and modified :
mD3dpp.PresentationInterval = D3DPRESENT_INTERVAL_IMMEDIATE;
fps increase from 30 to 40, still very slow. I do some profile like:

DrawPrimitive 9 vetex 3480 square 580 time 0
Clear 0 drawOneFrame 2 EndScene 0 Present 22
DrawPrimitive 9 vetex 3480 square 580 time 0
Clear 0 drawOneFrame 1 EndScene 0 Present 21
DrawPrimitive 9 vetex 3480 square 580 time 0
Clear 0 drawOneFrame 2 EndScene 0 Present 22

you can see the DP is very slow just 9 but the
mDevice->Present(NULL, NULL, 0, NULL)
cost too much

if hide all window just show fps text

DrawPrimitive 1 vetex 96 square 16 time 0
Clear 0 drawOneFrame 2 EndScene 0 Present 19
DrawPrimitive 1 vetex 96 square 16 time 0
Clear 0 drawOneFrame 2 EndScene 0 Present 17
DrawPrimitive 1 vetex 96 square 16 time 1
Clear 0 drawOneFrame 2 EndScene 0 Present 19

just 2 DP and Present near 20

Well, on my system it is always 60 with original options and 600-700 with D3DPRESENT_INTERVAL_IMMEDIATE in most demos, so it's hard to tell why yours fps is so low.
(Mobility Radeon HD3650, Core 2 Duo P8600, Windows 7 SP1).

I don't understand most of those values that you provided. What do you measure?

By the way - I have almost same fast results with OGRE's render.

You are right, Altren. I changed a Mechine and get the same result as you.
MyGUI is quick! I feel stupid to sumbit such a result not test enough, forgive me.

Now I guess it because video card. My video card is
Intel(R) G41 Express Chipset

Several users used MyGUI on iPhone, so may be it should work not so slow even on such chipset. And since it support Microsoft DirectX 10, Shader Model 4.0 I guess this chipset is not really so slow and problem might be in videodrivers or something else.
