Have you downloaded the latest driver for your graphics card? If not, you should do so through this link. Also, you could try setting Terraria.exe to low priority in the task manager, assuming you're using Windows.

Click Ctrl+Alt+Delete or Ctrl+Shift+Esc -> Processes -> Right-click Terraria.exe -> Set Priority - Low
