fps is slowing down

[Jochem Gruter]

My fps is slowing down. I begin at 60 fps and after 5 minutes it is 30 and after 15 minutes it is 5 fps.

@Override
	public void run() {
		Thread.currentThread().setPriority(Thread.MIN_PRIORITY);
		while (true){
			repaint();
			try{
				Thread.sleep(17);
			} catch (InterruptedException e) {
			}
			Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
		}
	}

My paint is in a jPanel and I've just painted some text and rects.

Use a Swing Timer, not Thread#sleep(...) for animation. And never never run an infinite loop or sleep on the EDT.

Also, Thread.sleep(17) will sleep 17 milliseconds, not 17 seconds.

*scratches head*

It's not necessarily on the EDT right? And 17 ms seems like a decent amount to get around 60fps.

Anyway, I don't see why the OP is messing with thread priorities.
