Hello I have an application running on a machine with a 24bit graphical card, and I want to set the video mode to 24bits, but.... It doesn't seem to be working. I set the driver as (...) GrSetDriver( "win32 gw 800 gh 600 nc 16M" ); (...) and the mode as (...) GrSetMode( GR_NC_width_height_bpp_graphics, XRES, YRES,24); (...) but when I check if it's in 24 bits... it tells me that it's in 32bits. If in the driver I change to 64k or 32k or 256 it will render the same result... I am at a loss. Any ideas? thanks in advance André
