Solved: 5 Years, 6 Months ago New Amnesia lagging extremely

[Helsinki]

Hello everyone,,
I'm having heavy lagging problems as in the framerate being low and the mouse hanging behind. I had no problems with the old Amnesia even on highest options.

It runs smoothly at first but once the splash screen shows up it starts lagging which gets more intense in the main menu and becomes unplayable when starting the game with black screen for several minutes (probably because it's taking too long to actually come to where you can see anything as it's lagging so heavily) in-game menu takes several seconds to show up and I have to click multiple times to select an option. The sound however runs smoothly without problems.
