Update 2.

In this update:

Mouse Inversion: Now inverts rotation only along the Y axis; previously, there was a bug that inverted all axes.

Improved performance of sound sources on rivers: previously, the position of these sounds was always calculated, regardless of your location. Now, only nearby sound sources are calculated. This reduces CPU usage by 10 times, and even completely disables all unnecessary calculations if you're far from rivers.

When driving, vehicles consume less CPU resources.

A vehicle that's not in use and simply parked places almost no CPU usage.

Some quest items could be picked up, and they would reappear after restarting the game. Now, they can only be picked up once.

Animals consume 10 times less water.
