I am having a strange problem.
Anytime I am polling for events, my frame rate drops incredibly. Even more so if I am moving the mouse while polling for events.
For example, with this code:
#include <SFML/Graphics.hpp>
int main()
{
sf::RenderWindow window(sf::VideoMode(800, 800), "SFML window");
while (window.IsOpened())
{
window.Clear();
/*
sf::Event event;
while (window.PollEvent(event))
{
if (event.Type == sf::Event::Closed)
window.Close();
if (event.Type == sf::Event::KeyPressed)
{
if (event.Key.Code == sf::Keyboard::Key::Escape)
window.Close();
}
}
*/
window.Display();
}
return EXIT_SUCCESS;
I get well over 1000 FPS with this code. When I uncomment the block polling for events, I get around 50 fps, and if I move my mouse around the window (slowly or quickly), it drops to a range of 1-20.
My specs are:
Q6600 Intel Core2Quad 2.66ghz
Nvidia GeForce GTX 260
3.5GB of RAM
I am using SFML 2.0
I don't think this is an SFML problem, as old programs I made in SFML 1.6 on a different computer, run slow as well on this computer. Also, my friend who also uses SFML 2.0, sent me a program he made that just displays the FPS in the graphics window. As I expected, I get the same low fps problem.
Are there any known issues that would cause this? I've already tried updating my graphics card drivers, and it hasn't helped.
Thanks.
Edit:
Operating system is Windows 7 32bit
Also, I have tried compiling my programs in both debug and release mode, as well as both dynamic linking and static linking, and I have the same issue.
