I want to improve my game engine I wrote for my PocketPC. currently I'm using GAPI for getting a pointer to screen memory, and I get only 30 FPS with just clearing the screen. I guess GAPI is really, REALLY slow and I was wondering, how can I do it faster? and no, I do not want to use any librarys like GAPIDRAW etc... So, I need to use ARM assembly?! Thanks.

I doubt you will do much better than GAPI, it is already very low level IIIC

Are you sure?
I know my PPC is old and slow, but 30fps while doing nothing?
do you mind checking the exe and tell me how much fps it run?

Some of the PocketPCs with video chips are really bus limited. You can't really do anything about it. I'd recommend picking up PocketHal @ www.droneship.com.

It has a few tricks, and sometimes can give you small boost or two.

ok here is the download
so if anyone have a ARM PocketPC and want to check it out for me, it will be great.
the "demo" is drawing 2 surfaces, and clearing the screen, when you press a key, the program will exit, and report average FPS.
please post them here.
Thanks.
