PC 30 FPS Lock

Proxy

Cultist
This has Bothered me for quite some time now.
but it wasn't allways there.
Sometimes the Game likes to Lock at 30 FPS, and fter a Random amount of Time goes back to 60.
It is Horrible in 30 FPS, and my Settings are already Low/Auto, and Frameskip is on.
my PC should be able to handle Terraria so Easily, but it Still Locks at 30 FPS...
what can i do?
 
That sounds like your GPU is V-Syncing.

What brand of graphics card do you have? Does it come with a settings manager?
 
Nvidia GeForce GTX 750 Ti
Alrighty, please try these steps (courtesy of @Marcus101RR):

Q: I am experiencing low frame rate for Terraria, but the machine passes as recommended?

A: If you are using nVidia Control Panel, you can select Terraria.exe process and change the specifications on how your graphic card handles the game. Follow these instructions:
  1. Open nVidia Control Panel.
  2. Select Manage 3D Settings.
  3. Choose Program Settings Tab.
  4. Select Terraria as current program.
  5. Turn Triple buffering and Vertical sync to On.
  6. Run Terraria and turn Frame Skip to Off.
  7. The application should be running better than your current setup.

It was Kinda Hard to Setup.
since my PC is German, so are the Names of Options and they are also in a Different Position.
but it seems to work. (still not 100% Stable 60 FPS, but no 30 FPS Lock as far as i saw)
Thank you.

Can you please tell me how to do this on AMD?

Unfortunately, I don't think that'll make a difference. This AMD FAQ gives instructions on how to turn off V-Sync, but according to that page V-Sync only works for OpenGL applications anyway, while Terraria uses DirectX. You could try it, see if it solves your issue, but I don't think it will.
 
I am also having this issue with the 30 fps cap. I tried your solution but it didnt work. Any suggestions? I dont think it is a performance thing because it was running at 60 fps just a week ago.
