new to this list, so this subject may have been discussed before..
currently writing a game in a 320x240x24 resolution, so i started out by
creating an unsigned char Array wish I wanted to contain my pixels ( doing a
lot of pixel based operations )
but my problem is that I only get 20 fps on a K6-2 350 and 60fps on a Cel
466 BOTH running with a TNT2 under windows .. have i made a serious error
somewhere in my "Copy-from-array-to-screen"-routine or ?
anyways.. it goes like this:
if ( SDL_LockSurface(video) == 0 )
Uint8 *src, *dst;
src = myscreen;
dst = (Uint8 *)video->pixels;
memcpy(dst,src,230400); // ( 320*240*3 = 230400)
SDL_UpdateRect(video, 0, 0, 0, 0);
