Hi, I'm not very good at programming.
I'm trying to learn more with SFML.
I wrote this joystick input test program to test a maximum of 4 controllers it's got a few problems mostly the fact that it's very sluggish at least for me.
Can anyone tell me why it's so slow? I feel like I'm doing something wrong.
Here's the whole thing
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/System/Vector2.hpp>
#include <SFML/System/String.hpp>
#include <sstream>
#define SSTR( x ) dynamic_cast< std::ostringstream & >( \
( std::ostringstream() << std::dec << x ) ).str()

edit: I didn't write the SSTR() thing, I stole it from the internet because I'm too lazy and stupid to figure out how to cast a number to string on my own
