@Electro40 There are a lot of particles in this save, and your computer is having trouble keeping up. Disabling heat simulation reduces the amount of computation that your computer needs to do, improving your frame rate.
disabling heat simulation will make it render faster for some reason
Image 2. Oh and, THIS IS SOME GPU LEVEL RENDERING CRAP
this was not on FP long enough
@mark2222 Thanks mark2222!
@thepowdertoy12 Thanks! If you have any questions, feel free to ask me in PM or IRC. Also, I'll be starting a tutorial series in a few days, so watch out for that. And oops, I realized that I haven't updated the Subframe Handbook to include the new particle-order manipulation technique... I'll get to that someday, maybe.
I think I have difficult to communication at IRC channel, because I'm korean. I'll pratice myself with your subframe handbook. Your handbook save is amazing. Thank you.
