Mirror's Edge Catalyst Graphics Performance Tweak Guide

By: Sean Ridgeley | Guides | Posted: Sep 25, 2016 11:31 pm

Overall Quality

 

The presets allow for easy changes in visual fidelity in performance by affecting all graphics settings. They are imprecise and don't cater to individual preferences, however, so it's very unlikely you'll see the optimal result by playing with these, but it's useful to observe the cumulative effect of changing multiple settings at once.

The benchmark shows Overall Quality has an unsurprisingly major effect on performance, although only between the Low, Medium, and High settings; the performance differences between High, Ultra, and Hyper are much less pronounced, which is perfectly in line with the visual differences. To put it another way, High makes for a good balance between image quality and performance.

Texture Quality

 

Affects the quality and sharpness of textures. In Mirror's Edge: Catalyst, the difference is difficult to notice in many scenes; in the one below, it's only obvious in the ground textures and the graffiti on the wall, but even then the only change really is seen between High and Medium.

As is often the case with Texture Quality, no definitive impact on framerate is observed when changing this setting, although this could well change if you lack in VRAM. Most should keep it at the maximum setting; if you're on a lower-end card, try High and work downward from there.

Lighting Quality

 

Affects the resolution of various lighting in a given scene. In the screens here, it's noticeable on the couch to the left as well as on the ground in front of Faith, much moreso when changing between High and Medium and Medium and Low.

In these screenshots, the differences are most noticeable on the wooden railings and ground surfaces; quality improves significantly between 1X and 2X settings, as well as between 2X and 4X.

Testing reveals this setting comes with a significant framerate hit at all levels. Given how difficult it is to notice any improvement on Ultra and Hyper and the startling degradation at Medium and Low, High makes for a great choice if you're looking to save on frames without sacrificing much visually. You can save further with Medium and Low, but it's nothing to write home about.

 

 

Reflection Quality

 

Affects the presence and quality of reflections off certain lights and objects. There's no meaningful difference observed in the screenshots here between Hyper and Ultra or Ultra and High, but you can see a slight change between High and Medium, where the reflections on the floor become more vivid – less realistic perhaps, but not necessarily less appealing visually. At Low, Reflections are almost completely absent and make for a very ugly sight.

Corresponding to the lack of visual differences, the only truly major performance discrepancy here is seen when employing the Low setting, which offers about an extra four frames across the board. Most should leave this setting at Hyper.
