Precipitation performance problem

Hi there,
I was looking through Tim Aste's great content pack(s) and was thinking about trying the environment stuff.
So I created a mission for my game and added the precipitation blocks from the example mission files, just to see how it worked.
I got it to work, but it really killed the frame rate on my Power Mac G5 2x2GHz with 1,5GB ram and a ATI Radeon 9600XT card.
According to OpenGL profiler the FPS is at 0-2 with the precipitation active.
I ran Shark and the OpenGL profiler but I really couldn't see anything there so I'm not sure what to do, is this a known issue?
EDIT:
Forgot to mention that I'm on Mac OS 10.3.8 and using TGE 1.3 with synapse's lighting pack
Thanks for any help

I changed that to a much lower number (300) and the frame rate is up again.

Oh, now I feel kind of stupid... I looked through the mission file again and I saw that the variable numDrops was at 3000.I changed that to a much lower number (300) and the frame rate is up again.

Yeah... lots of particles are costly to render. Glad you got it resolved! :)

And i only have a 1g with gforce 5200 without any huge fps drops.
I dont have Astes enviroment pack so i cant give you any clues.
But i think sonething else must be wrong.
But this is on a PC :)

running it in the defualt mission is fine though.
might have to lower the particles and see what happens :)
this was on a p4 2.8 pc .

Odd. I recently ported over the same precip data blocks from the enviro pack into our machine and framerate died down to 1-2 fps.running it in the defualt mission is fine though.
