Lag/ Stuttering in Amnesia

[plutomaniac]

You say that this problem occurs on other games as well meaning that this is a system-wise issue and not directly related to FG games. For FG games, I suggest you do a file integrity check via steam (or a reinstallation for retail versions) in case the lags occur because of corrupted files or similar. Also, make sure you have the latest AMD drivers installed for your graphics card and even if you do, do a clean reinstallation as mentioned at the graphics card troubleshooting guide.
