I'm working on this game: yt alpha preview

I came into a huge game-breaking problem - after 10-15 min of gameplay the FPS drops from 60 to 30 and is very unstable. I'm using tons of physics and particles, I'm deleting and nulling everything I can after it's supposed to be removed, I remove objects from vectors etc. The memory usage is stable at around 150mb so a leak is unlikely (or invisible?)- after a round ends and I delete everything, play a new round and performance is still terrible. I spent two days trying to figure this out and I just can't fix it. Maybe I'm missing something? I know it's hard to help with no code but I would just have to post my whole source.

I've been looking for a solution to this for years, but nothing is conclusively documented. There are many Shoutcast Flash players out there (e.g. radio.de) so I know it's possible. However, most of my research leads to this: s = new Sound(); s.loadSound ("url.of.shoutcaststream:8003",true); Which… >>> More
