Hi Alan
I run pIllusion for the first time after more than one year; I downloaded all new libraries and also a sw upgraded, that made me impossible to run PI again; I had the same problems reported in this post and in a previous one:

I copied the old EXE (as you suggested) and now PI works again.

Any new solution since May? What am I missing in 3.0.4.c?

Hi Vincent, Alan, Elvis and everybody.
I had the same problems of Vincent when updated to 3.02: all examples and all my old project were extremely slow; also emitters preview was very slow. Only particleView showed emitters at normal speed.

I have Parhelia 128 too. After reading last Alan’s post I downloaded from Matrox website drivers version 2.5.1.30, sep 11 2007.
I had some trobles after installing (I had to reboot several time, and reset PI preferences and video card settings), but now PI runs at normal speed again.

Thanks.
