Hi, I'm actually total newbie so please don't scold me if i had murdered any program 
I'm trying to create little project, so i start from creating display, two bitmaps (one static 800 x800 and 2nd moveable 40x40) and bind lesser one to arrows. After I take first attempt to run program, i was able to see delay in move of lesser one; After long research i found that drawing large bitmap take much more time then expected.
I'll place here most important parts of program:
Resources.h:
1class player
2{
3 public:
4 float player_x;
5 float player_y;
6 int lifes;
7 int firepower;
8 int speed_of_player;
9 ALLEGRO_BITMAP *player_image;
10
11};
12class game
13{
14 public:
15 ALLEGRO_DISPLAY *display;
16 ALLEGRO_EVENT_QUEUE *event_queue;
17 ALLEGRO_TIMER *timer;
18 ALLEGRO_DISPLAY_MODE disp_data;
19 player *tab2;
20 monster *tab;
21 int map[15][15];
22 game();
23 void gejm();
24};
Functions.h

4 kwadrat=al_load_bitmap("square.bmp");
5 player gracz;

7 gracz.player_y=500;
8 gracz.player_image=NULL;
9 gracz.player_image=al_load_bitmap("player.bmp");
10 gracz.speed_of_player=1;
11 bool redraw=false;
12 bool key[4]={false,false,false,false};

14 al_get_display_mode(al_get_num_display_modes() - 1,&disp_data);
15 al_set_new_display_flags(ALLEGRO_FULLSCREEN);
16 display=al_create_display(disp_data.width,disp_data.height);

28 al_wait_for_event(event_queue,&ev);

44 }
45
46 else
47 if(ev.type==ALLEGRO_EVENT_TIMER)
48 {
49 redraw=true;
50 //if(key[KEY_LEFT])
51 gracz.player_x-=gracz.speed_of_player;
52 }
53 if(redraw==true&&al_is_event_queue_empty(event_queue))
54 {
55 al_clear_to_color(al_map_rgb(0,0,0));
56 al_draw_bitmap(square,0,0,0);

So if you would know where did i done mistake, i would be gratefull for pointing it
