2. Improve your network connection. Terraria lag may be noticeable if there is a problem with bandwidth, network congestion, bad routing, or an unstable connection. Try using a wired connection, increasing your bandwidth, or switching to a better ISP to improve your network connection. You should also look to see if there are too many applications running in the background, such as chrome tabs, as these can seriously impair the performance of your computer configuration.

What Can I Do If Terraria FPS Drop?

If you want to boost Terraria FPS, try these suggestions as follows:

  • OS: Windows Xp, Vista, 7, 8/8.1, 10
  • Processor: 2.0 Ghz
  • Memory: 2.5GB
  • Hard Disk Space: 200MB
  • Video Card: 128mb Video Memory, capable of Shader Model 2.0+
  • DirectX®: 9.0c or Greater

2. Use the full-screen mode. The game requires more computer processing power to run in full-screen mode.

3. Both the graphics settings and the in-game resolution are far too high.

4. There are far too many background programs. If you have a lot of Chrome tabs open, for example, they will consume a lot of energy, leaving only a few to run Terraria. As a result, FPS drops in Terraria are common.

5. Terraria's game files are corrupted. This game could be reinstalled.

6. Insufficient network connectivity. For example, if your network or bandwidth is congested, data transmission speed and the number of frames displayed on the monitor will both decrease.
