Lately I've been having a major problem with some type of apparent memory leak in PS2. I tend to live for a long time, sometimes hours. The problem is that over time my FPS will drop and drop from it's normal around 70 down to around 15 and then eventually into single digits making it unplayable. When this eventually causes me to die, my FPS go back to normal on respawn, The fact that this is fixed by dying, and that it is a recent thing without anything changing on my computer, obviously shows that it is a game bug and not a video setup problem. I haven't been able to determine any specific thing that causes it to slow down, but it does seem to start off suddenly and then just get worse and worse. This started a couple major patches ago, before which everything ran pretty perfectly.
It's a balancing feature. If you're on a streak, the game reduces your FPS till newer players get a chance to pop your dome.
Doesn't sound like a memory leak, more like a datastructure that continues to grow in size and the computation over it becomes more and more expensive. Seems to me like a performance bug. A memory leak occurs when memory is not freed but all references to it are forgotten.
