I am working on some installation on my Mac machine, but the installation will be actually displayed on a PC. Yesterday I tried for the first time my patch on a PC and the render was very different. The patch runs a particle system that has no textures - it's just geometry matrix. And the way that that mass of points and lines is displayed is very different (regardless of the color variations).

1. Do I need to install anything specific on a PC machine for a optimal working of jitter on a PC?

2. Is the problem only in various graphic cards?

A screenshot of each render would help the forum in trying to identify the problem.
