I've had this problem a few times now... I'll be sitting in some sim, and if I watch my FPS, it starts to slow down... despite no change in the sim that anyone is able to determine. It doesn't drop for anyone else either, but it will slowly grind its way down to about 0.5 fps... And never go back up. If I teleport away, and come back, it's normally fine. Sometimes even when I teleport away, though, the FPS drop remains and I have to relog. Not always, however.

Anyone got any ideas what the problem is?

Sounds like the classical behavior of a memory leak. Whether it is in the SL Client, OpenGL libraries or lower level drivers. I've experienced the same phenomenon, with the same "fixes" working at unpredictable times. The only regularity I've noticed is that is seems to be induced by going to prim and AV heavy zones. Minimizing the SL window and re-opening can often have the same effect.

reitsuki have you tried doing this with the alt+2 frame console open.. it may give you an idea of what the computer is spending the most time doing. (it splits up each frame into the time the client spends in each operation, the network access, getting the geometry, transforming it for rendering, doing the texturing, the lighting, etc etc)

if all of them go up, but they stay relatively evenly it may not even be SL but your actual computer slowing down... if one specific part goes up (say network latency) it could be a problem with yout connection... or say its geometry, could be a problem with your video drivers, etc

I was noticing a slowdown as well, but I thought it had something to do with my recent switch to DSL. I percevied that the frame rate slowed with the network activity but maybe the reality is that itt's the other way 'round. *shrug*

Anyway, it's been a bit better for me lately (last day or two).
