viewport extremely slow with max 2011

so i'm trying the demo of box#3 on my 3ds max 2011 64bit and i can't make it work properly, my viewport is extremely slow and there are not even so many particles in the scene. It takes over 2 minutes to update the scene at any change, and if i increase the number of particles it can take over 2 hours to get nowhere. I'm using OpenGL, but there's no big difference with directx 9 or 10. I read on a forum that pflow is not desisgned to work on machines with AMD cpu and ATI gpu, is that true? No particles for me on this machine?

these are my specs:
CPU: AMD Phenom II x4 3.2 ghz
GPU: Sapphire 5770 HD 1gb
ram: 4 gbs ddr3
OS: win7 64 bit

False.

The update speed can be related to the vewport shading mode. First, check if the Display operator is set to "Ticks" for viewport show. Second, check what you have for viewport shading, and see if switching to Wireframe makes any difference.

If the issue is with some specific Box#3 data setup then please upload your scene - so we can look on what's going on.

Thanks,
Oleg B.

i resume this topic, cause i'd really like to use pflow and krakatoa. Since it was almost impossible to work with a decent amount of particles, i switched for a while to cinema 4d, and the mograph and particle system update in real time whatever the settings are. I wish my pflow worked this good.
Searching on the internet i learned that pflow is singlethreaded, so even with a quad-core CPU it'll always use only 1 core. I could disable the multithreading, so that pflow could use the whole CPU to work, but of course this will give me problems with the native multithread elements of 3ds max, like mental ray. I can't switch back and forth from single to multithread, it'd be impossible to work like this.
Isn't there a better way to give pflow a little help?
