Thanks for replying, using a small ammount of noise in the force field WITHOUT hairy dinamycs enabled help to create a lite animation for a large ammount of hair particles without need for long bakes and physics configuration for the hair particles effect, things that (for me at least) usually takes a lot less time without quality loss in much scenes, configuring physics and baking everything takes much more time for pretty much the same result on not important things, the force field noise animation without hair dynamics enabled is a feature that i personally use a lot, and i wouldd really like to use it in 2.8, so i created this post... (For the people that says it is just a glitch animation, it is not, in the example file in this post i just made a random situation to se the animation bug, with a bit of configuration the result is really enjoyable for a lot of situations)
