#### Some Drawbacks with idStudio

- idStudio itself is ~60 GBytes
- Individual map asset packs are 5-10 GBytes
- You will need to login to your Bethesda account to access/publish mods
- You need a fairly powerful PC to optimally run idStudio (32 GBytes of RAM is recommended)
- idStudio may take a some time to do the following  
     - Boot up  
     - Open a map  
     - Load into a map  
     - Package a .map file (packaging decls, strings, textures, &amp; audio will only take a few seconds)
- Packaged map files can range from 500 MByes to 2 GBytes in size depending on how large the maps are
