Which special effects in World of Warcraft must be turned on and which special effects do not need to be turned on?

When opened, the shadows of your characters and mounts will be displayed according to the sunlight. The higher the effect, the clearer it is.

The interface should be open. But that thing doesn't accelerate when it's on. So it's still a question of sound and video. Video, ordinary FB, games, all minimum online.

Other effects can be ignored. Another influence is the weather, which affects the sight distance. You can adjust it according to what you see. It doesn't really matter. If it is the lowest, it will not affect your PVE and PVP. I just can't see the grand vision.

Although the effect of full clearance is a little poor, when you are stuck and don't know where you are, you will be very idle, so it is better to close it all. However, the option of projecting these three lines of material is suggested to be checked. When you get off FB, you can see the trap of BOSS and some special skills. It's important to save your life. Otherwise, there will be no output and treatment.

This configuration, I suggest you turn it off completely, or there will be more people, and you will be stuck in the city. Although the effect of full clearance is a little poor, when you are stuck and don't know where you are, you will be very idle, so it is better to close it all.
