Doom Graphics Performance Tweak Guide

By: Sean Ridgeley | Guides | Posted: Jul 1, 2016 1:10 am

Depth of Field Anti-Aliasing

 

Judging from the name, this setting adjusts the level of aliasing observed on elements affected by depth of field. Again, we could not find examples of this in our testing, so screenshots have been left out of this section.

Nothing to see here. Once again, no performance differences are observed when changing this setting.

 

 

 

HDR Bloom

 

Bloom is a divisive shader effect that sees light emanate from bright spots in a given scene.

In Doom, it's observed rarely and even then, it's subtle. Our screenshots show an example of it in action in the foundry: observe particularly the metal structures to the right of Doomguy which gives off a bright aura with this setting enabled.

The benchmark shows HDR Bloom has a significant impact on performance. Whether you like it or not, it's a non-essential yet somewhat costly effect, and so makes a great candidate for tweaking.

 

 

Lens Flare

 

This setting affects whether or not light is shown as artifacted or hazed, typically when looked at directly. Unfortunately, we again could not find examples of it in our testing, so screenshots have been left out of this section.

The screenshots show Lens Flare has no definitive impact on framerate and so can be enabled or disabled as you see fit.

 

 

Lens Dirt

 

Judging from the name, this setting changes whether dirt and grime show up from a first person perspective in particular environments. Unfortunately, we again could not find examples of it in our testing, so screenshots have been left out of this section.

The screenshots show Lens Dirt has no definitive impact on framerate and so can be enabled or disabled as you see fit.
