memory fragmentation

hey, in my particle system i am freeing and recreating lots of particles. will this lead to bad memory fragmentation. and if it does will the slowdown be that noticeable?
thanks

Not sure about memory fragmentation but the extra CPU cycles required to create and free lots of particles will lead to a noticible slowdown - how much depends on how many particles you are creating/freeing.
It will be faster to use a pool of a fixed number of particles and just cycle the EntityAlpha value and do a HideEntity when Alpha = 0.
To re-use the particle do a ShowEntity and set Alpha = 1.

good idea and thanks for the response. if will cause computers to be unstable and slow then i'll just use the pool thing that you suggested. thanks :)
