Hello!

I have noticed that my FPS goes down overtime. I also realised that even if it's lagging as hard as it is on the video, if I press ESC the FPS jumps to 60FPS while I'm on the main menu.
Settings don't seem to affect this at all. I play it on extreme, and even if I play on lowest settings there are, the problem doesn't change at all. Not even a slight improvement.

Game version:
1.10.153598

My specs are:

CPU:
Intel i5-3350P @ 3.10GHz

GPU:
Nvidia GeForce GTX 1080

RAM:
8GB 1600MHz DDR3
