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 well (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, & 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
