Do Particles use CCD for Collisions?

I didn’t find any info on this.

I am wondering if it’s possible to do things like projectiles etc. with CPU-based particles. So I’d like to know if particle collisions work reliably at (very) high velocities. I want to trigger collision-callback-functions with them (though I’m not sure how yet - the class I am meant to derive from I can’t find…).

And it would also be interesting to know how this is handled for GPU-based (and other kind of) particles. I figured out that event-callbacks don’t work with GPU-particles, but no idea about CCD.

Today is bumping day.
