I’m not sure it’s a problem. On my laptop, pIllusion uses 90%+ cpu when the
preview is animating a complex super emitter. If the preview window isn’t
doing anything, it uses 0%. Simple emitters use less cpu % (some are only
5% or so).
So a dual cpu machine would max out at 50% since it’s only using a single
cpu (as I understand it).
I wouldn’t reinstall Windows.
