… or just generate a mapfile and enable profiling and look at that :slight_smile:

My assumption is that SDL_UpdateRect() will be the slowest part of that
loop, but you might be surprised to find that the bottleneck is your own
code. It happens.

Put timers between each stage to see where the bottleneck is.

#include <time.h>
clock_t clock1,clock2;

clock1 = clock();
//put your stage 1 here
clock2 = clock();
printf(“stage 1 completed in %.0f
ms\n”,(double)(clock2-clock1)/CLOCKS_PER_SEC*1000);

clock1 = clock();
//put your stage 2 here
clock2 = clock();
printf(“stage 2 completed in %.0f
ms\n”,(double)(clock2-clock1)/CLOCKS_PER_SEC*1000);

etc.
