well, judging by the window caption on your screenshot, you may be used, or even prefer viewing small fonts with no antialiasing whatsoever... which will obviously produce a crisp and sharp rendering of the glyphs, but with more visible jaggies on curved features.
You say that i should just turn antyaliasing off in api call used in this
prog to draw fonts or second option just correct gamma this ? - maybe this is as simple, I overlooked this (As I said this is not my program but i was wandering what cause of this problem is, i thought it is maybegeneral problem, but maybe it is just easy as you say, TNX)
