Spectator Mode Eye Settings

The first thing you need to decide is Audience perspective. You can choose left eye or right eye for this. Valve recommends that you choose the eye you want to aim down. So if you tend to close your left eye when aiming at your target, choose your right eye.

Onlooker mode smooth setting

In the same menu, you can also choose to turn smoothing on or off. That setting Eliminate jitter This is the result of fast turns in the game. Once turned on, you can start from Low, medium or high. Of course, this only applies to the viewer view.

This effect is applied in real time and has a small impact on performance.

HUD is another element that may not always be shown to the audience. This option allows you to turn certain HUD elements on / off specifically for the audience view. By default, the HUD displays health, ammunition, resin counts, and any items you carry.

But you can turn off the HUD completely, or you can control the size of the HUD by: Small, medium and largee.
