Thanks @Korina, I've done it. However, I think that is a workaround, and that the problem will be still there (for instance, changing the window between different frequency monitors).

Hi. I've just tried windy in a 300Hz monitor, and the wind particle trails (and so, the own particles) are almost invisible. I tried lowering the monitor's framerate to 60Hz, and that solved the problem, particles and their trails were Ok.

So I guess the lifetime of a particle is depending of a number of frames, rather than a timer, creating very different visualization experience depending on the display device.
