Gamma problems in fullscreen mode

[deee]

Hello,

Sorry if I am being redundant, but the search function doesn't work.

Problem:
When testing my game in windowed mode, everything works properly.
Now when I test it in fullscreen Mode (Strg-F5), it all looks fine at first, but when i change the gamma-value and set it back to 1.0, everything gets way too dark.
The same problem appears when I restart the game with the F9 key in fullscreen Mode.

Graphic device : Direct3d

Does anybody know a solution to this or has anybody encountered the same problem ?
I would really like to implement a gamma slider to give the user the opportunity to tune things perfectly, but changing the gamma value in AGS always leads to an odd outcome : 1.0 is too dark overall and setting it higher causes the lighter areas to become too bright while the darker areas still are too dark.

Try the DirectDraw driver; The Direct3D driver is known to have some issues.

Thank you very much, Khris, bist eh der beste

No Direct3d, that leaves me quite sad, I was so happy to find a workaround that fixed framrate problems and other issues I had with Direct3d.
The sprites and basically everything looks much more smooth and fluid in Direct3d, Direct Draw is just a soup of pixels

It would be great if anybody knew a solution to solve the problem and help me avoid being forced into Direct Draw.
It is wonderful to see that there are other guys also working with Direct3D, I just stumbled into Alan v.Drake's thread about fixing the scaling in D3D, so D3D doesn't actually seem to be dead due to the existing bugs.

The sprite difference between DDraw and D3D is huge, as you can see:
