Switching characters loads the characters into memory but never frees up memory when switching. So I had my memory (RAM) hit as high as 2GB! Switching characters would cause it to climb higher.

Workaround:

• Remove the other character folders you are not using. This way you load into your custom model / preferred model. When loading HONK this should make it so only your character loads in.
• Always start a fresh instance of HONK so memory is freed.

I went from 2GB memory usage to 250MB usage after making this change. 

I made a model at a very high resolution which is why I have such a high memory usage. Default models would only take 50MB.
