Hi, when I try to blt from the backbuffer to the window i''m running in the picture gets blurred / antialiased. I''m using Direct Draw 7. Is there an option to disable anti-aliasing in blits or something? Thanks, Johan Ersvik

maybe: source_rect<>dest_rect => streching?

No, in my case, source and dest have the same size

Since I last checked direct draw does not perform antialiasing. The "Aliasing effect" occurs when there is a source to dest size discrepancy. Also please note that blitting rects are strange in DirectDraw. To fill the screen you dont do (0,0,799,599) but (0,0,801,601).
