Time to upgrade the hardware?

In the computer gaming world there is a way to increase the fps rate by adding a fog to the world. This way the drawing distance is lower and the stress on GPU is lower and thus the game runs smoother.

The fog on games starts to bug after a while even though it sometimes is realistic to have ridiculously low visibility. Unfortunately on some games, especially the older ones, the fog is there 24/7.

Nevertheless it is pretty neat to experience such a fog in real life every now and then.
