Terraria Errors, Crashes, Connection, Performance Fixes

If you face any error, crash or other graphics and performance issues while playing Terraria, you can refer to the troubleshooting guide below for the workarounds to fix these issues.

1# Install .Net Framework
You must install the .Net Framework 4 otherwise your game will not work. Download the required version 4 from here.

2# Install XNA 4.0
XNA 4.0 is also required – Install .Net Framework first and the XNA 4.0 after.

If you are facing any trouble installing XNA 4, install XNA 3.2.

3# Make sure your video card supports XNA
Check it by going through this list.

4# XNA or DirectX Related Crashes
Re-install DirectX 9.0c and XNA if you encounter any crashes related to these. If you don’t have the DirectX installed already, then you can download it from here.

5# Make sure your drivers are updated
Keep your drivers updated, download them from nVidia and ATI portals.

6# Full Screen Mode is not working
You can enable the full screen mode from the options but if due to some reason it is not working then you can simply press ALT+ENTER for the full screen.

7# Configurations are not changing
If you are not able to setup new controls or change the existing ones then go to
My Documents/My Games/Terrariaand delete the file config.dat and restart the game.

8# Low Frames Rate and Performance Fix
Update your drivers as mentioned above and try reinstalling the game and the required software (XNA, .Net Framework) as well. Make sure you don’t have anything open which may interfere with the performance.
