Cannot disable DirectDraw/D3D Acceleration

[Pio]

Honored you,

first of all sorry for my bad english and sorry if I post this one to the wrong forum, but I don't really know that is this a video card or monitor or driver problem.

So I wanted to disable DirectDraw Acceleration in dxdiag. On winXP the method was:
dxdiag to the Run...
Display pane
In DirectX Features there was a button next to the DirectDraw acceleration to disable it.

Here is a picture about that:

But in win7 these Disable buttons ara not available for me:

There was another option to disable directdraw acceleration, but it is not available too.
It was:

It is now:

I tried:
- reinstall monitor driver
- reinstall video card driver
- disable Aero
But didn't help.

My monitor is: Samsung SyncMaster 225MW on DVI port (1.0 driver, this is the only one available)
Video card: GeForce 8800GT (185.85 win7 driver)
I have 32bit win7 RC(7100)

Can anybody help me to disable directdraw accelaration?

Thank you for your help!

Pio

Why are you needing to disable DirectDraw?

 

[bokica]

To play some older games like panzer general.
DirectDraw acceleration must be disabled or the colors are mixed.
I done it on xp without problem , like that guy pio posted year ago.
It seems to be some driver problem.

Bumb,

same problem. I can't get fallout 3 to work (without crashing every 5 minutes) and someone suggested turning of "AGP Texture Acceleration" Which is also un-editable as in the first picture...

Please anyone?
