So today i was testing new update to my game basically i hosted a server another client joined in and we were enjoying a gameplay. After a couple minutes ago i looked at the task manager and my game where i was hosting a server took about 2GB of ram and it was jumping up 5MB every second so i closed it and return to game after next 15minutes the game crashed. I looked at the crash log and found that the game has run out of memory. So my question is can i somehow optimize my game without unity pro? I looked allover the internet found some information about unloadAssetbundle but i don’t know how can i do it / write it in a script im so upset 
. Thanks for any help!
