Issues fixed

Game crashing/freezing/stuttering and weird behavior

Seems to affect mainly Windows 7 users, most likely because of the game not having access to enough RAM. Freeing up RAM by closing background applications or increasing the page file size may help. Also disabling fullscreen optimizations on Windows 10 may solve stutter issues.
Increase page file size (Windows 7)[citation needed]
  1. Press Start
  2. Search View advanced system settings and select it
  3. Under Performance press Settings
  4. Under the Advanced tab press Change
  5. Check Custom size and input your numbers. It is best to put the initial size the same as 'Recommended', and the max size around 1.5-2x that value. Remember to press Set before pressing OK.
  6. You will need to restart the computer for it to take effect
Disabling fullscreen optimizations (Windows 10)[citation needed]
  1. Right-click RainWorld.exe
  2. Click Properties
  3. Under compatibility section there is a checkbox named "Disable fullscreen optimizations"
  4. Check it
  5. Click Apply, then click OK
