Hardware (blting) acceleration in window on windows |

Forgive me if this has been asked before:
Is there any chance that SDL will be modified to use hardware blitting acceleration when running in a window on MS Windows? I ask because there is another graphics library (not as functional as SDL and for windows only) called CDX, which allows this. Using CDX in my application (an action game) I am getting frames rates of around 400 fps. Using SDL I get 40 fps. I did have a look through the code myself but was a bit baffled by all the DirectX stuff (the reason i am using a Blitting library in the first place ). Anyone else want this feature? Any comments?

Hi,
yes, there is another way.... you could use glSDL. In my website (www.megastormsystems.com) I have a little benchmark utility and you can see the differences between ddraw,d3d,software and glSDL. Further information of glSDL can be found here: http://icps.u-strasbg.fr/~marchesin/sdl/glsdl.html and latest SDL with glSDL included can be downloaded here: http://icps.u-strasbg.fr/~marchesin/sdl Cheers ----- Original Message ----- From: Dean Ware To: sdl at libsdl.org Sent: Thursday, January 05, 2006 5:53 AM Subject: [SDL] Hardware (blting) acceleration in window on windows Forgive me if this has been asked before: Is there any chance that SDL will be modified to use hardware blitting acceleration when running in a window on MS Windows?
