I downloaded swat4 demo.
It has too dark swats and shadows.
http://bugs.winehq.org/show_bug.cgi?id=8848 (which is reported here too also with demo)
I think I figured out what is causing it.
I noticed that setting windows registerykey useGLSL=disabled made swats look like normal (see my sent pics).
I debuged the game and there wasn't many different lines.

etc etc
But I think wine is missing the next feature, what's causing the black shadows

"You can include the D3DSGR_CALIBRATE value for the first parameter of SetGammaRamp", well its definitely trying to set gamma, but it's IGNORED.
Here are the pics, before and setting that useGLSL registery key

But setting that registery key dosn't help on shadows which are too dark.
According to my knowledge reading some part of that Microsoft explanation making this setgammaramp function shoulnt be too hard, it just adjust the amount of RGB.
