To fix this problem, right-click your game's name in your library from the Steam menu and select the last option: Properties.

In this new window, select the "Local Files" tab to bring up the directory where you've install the game. Locate the game's executable file (.exe file) and right click it, then select the last option again: Properties.

This will bring up a new window for the game itself. Head over to the second tab: Compatability. Check the box "Override high DPI scaling behavior. Scaling performed by:" and then in the drop down box select "Application" if it isn't already selected.

That's all you need to do. Now, re-load the game and you should be good to go. If you already changed the in game sensitivty, I'd recommend either setting it back to default or your previous settings. Now go kill some giant insects!
