When it crashed my CPU usage went from 16% to 30%
Oh, I see. I crashed, it says Memory read/Write error. Implying that either your memory is corrupt, edited in a strange way, or all RAM is used up (Latter is much more likely). So I believe that particals have a RAM adress storing their data, velocity, X,Y, tmp, temp, Heading, life etc.
And Constantly accellerating them causes the velocity numbers to become bigger, and the X and Y changes faster, meaning more memory accessing, and the increased mem use of all of those Photons add up.
Creating two scenarios, 1. You run out of memory, end of story, game crashes. 2. The velocities grow so big that it causes a stack overflow creating an exeption that TPT does not know how to handle, leading to a crash. #1 is much more likely, but I cannot tell for certain what occurred.
I got the bluescreen. The mods should figure out why this is happening... +1
Also with Protons you can make a bunch of elements using this acel grid like noble gas, hydrogen, co2, plasma (probably made from the ionising noble gasses)
