I did some experimentation which confirms Mylenium's analysis. I am using layer exploder with subsequent particle behavior determined by the Velocity Dispersion and some interparticle Repel. Both the Velocity Dispersion and the Repel Force Radius are dimensioned in pixels, so when you lower resolution, pixels get bigger as a fractiion of screen size and the effects change. Dispersion Velocity is faster and the Repel force extends over a wider range giving even more dispersal. I have enough RAM that I can preview the critical frames at full-res. But Thomas is right, AE should be fixed so that when previewing at lower res effects with parameters dimensioned in pixels are adjusted so their effect is the same as measured in fractions of screen width. I think a linear scaling based on the resolution reduction should do it.
