Doom Graphics Performance Tweak Guide

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

Rendering Mode

 

Changes the filter the game is rendered with, offering a slightly different aesthetic with each one. 'Cinematic' is also letterboxed for a movie-like feel.

Testing tells us this setting has no effect on framerate, so feel free to use whichever you like best.

Sharpening Amount

 

A filter that affects how sharp the entire scene appears. At 0, it's quite muddy; the default 2 offers a much clearer view, and 4 offers a very appreciable crispness that 2 doesn't offer.

The benchmarks show this setting has no discernible performance hit. As such, most everyone should be good to keep at the maximum.

Film Grain

 

Alters the presence of grain in the game image for a gritty feel. It's a highly preferential setting, but if you like it, definitely try it out with the Rendering Mode options.

As you'd probably expect, this setting has no effect on performance whatsoever. Use however much you like without fear.

UI Opacity

 

Changes how transparent Doom's interface is; lowering it means an arguably more immersive experience at some expense to awareness.

Unsurprisingly, this setting has no effect on performance.

Final Thoughts

 

Doom offers a massive amount of graphics options, although as you can see, a lot have little or no effect on visuals or performance (as far as we could tell anyway).

 

In any case, to help you sort through it all, the key options are Anti-aliasing, Chromatic Aberration, Field of View, Player Self-Shadow, Directional Occlusion Quality, Reflections Quality, Motion Blur Quality, HDR Bloom, and Sharpening Amount. Most of these affect performance moderately or majorly, which a few only affect visuals (and greatly).

 

Happy tweaking!
