[Dev-C++] Graphics

[<ste...@ge...>]

Hi there.

I'm working in DOS. I know all about getting into 320x200x256, and it's =
working really fast and great :-)
But I really would like to go into 640x480x256 or even with more than =
256 colors. I have managed to do that, but it seems really slow useless. =
Can anybody help???

Thanks! :-/

In DOS graphics modes, graphics output usually result in writing to =
individual pixels in video ram, so the amount of pixels will determine =
how fast/slow your program runs. 640*480 instead of 320*200 means the =
speed will be about  4-5 times slower. Unless you use hardware =
acceleration, you can't do anything about that. (If your program runs =
more than 4-5 times slower, something is wrong - in this case you should =
give more info what exactly you are doing.)
