Chromatic Aberration remover

Tired of the eye-bleeder known as chromatic aberration? Want it to be gone?! Read on my friend!

What is this 'chromatic abomination' you speak of?

Chromatic aberration is a phenomenon which happens when lens (or lenses) fail to focus the whole light spectrum into a single spot (or at least close to it). Instead of natural looking image, you will end up with colour distortion, especially on the edges of viewable area and on objects which contrast well with the background or other objects. CA is also known as colour fringing or colour separation.

CA looks like this:


This issue was solved in various ways and to various degree centruries ago, ranging from introducing multiple lenses into the optic system, their surface treatment (faceting, coating, etc) and in recent times also digital processing algorythms which are filtering out remains of this nasty.

But why is it even in the game when it's considered being a detrimental side effect?!

¯\_(ツ)_/¯

CA has some light usage mostly seen in video editing and perhaps artistic photography, but looking at it in 3D games for extended periods of time might cause increased eye strain, temporary blurry vision, shifted depth perception and general inconvenience to many users.

However, If you read this far the chances are you want to get rid of it already - so without any further ado, let's do this!

Chromatic aberration removal

CA occurs when ingame PostProcessing quality is set to high or epic preset levels. Turning them off or to medium presets gets rid of CA, but unfortunately it also disables other post processing effects like HDR etc which you might want to keep on.

The way to do it is to edit Engine.ini file which is located at your system drive - most likely C:
The path to it should be like this: C:/Users/YourUserName/AppData/Local/redout/Saved/Config/WindowsNoEditor/Engine.ini

Open it with your prefered text editor and add in the following:

[SystemSettings]
r.SceneColorFringeQuality=0
r.SceneColorFringe.Max=0

Save it, close it and you are ready to give it a try without CA!

Steam Cloud note:

If you happen to have steam cloud enabled, you will get a warning where your local data are not matching saved cloud data - this is normal and to proceed with the changes opt to upload your local data into the cloud, otherwise the change won't take effect and the file will be reverted back to its original state prior to editing.

We are done!

That's it, simple as that! Although shouldn't it be included in the options natively?!
Anyway, enjoy the considerably less blurry image with no CA at high/epic postprocessing presets.

Hope it helped you and your sore eyes too!

Note:

If the image still appears way too blurry, it's because of the anti-aliasing method used ingame. Also it's possible that the AA preset is once again tied to more than just a single effect.

P.S. If there is interest in this topic, I will likely edit and expand the guide in the future.
Now go and rip it up!

In order for the setting to apply while changing other, in-game settings, make sure Engine.ini is set to "read-only."

This might also be alleviated by the Gear VR mod.

thanks, i wil try this in the future when i finally care to install this game

Thanks! Anyone care to further expand on Chromatic Abberation?

I have turned off this effect. The race times have improved. The tracks, for example, on Mars or Abruzzo can be played more pleasantly.

I love this fast game, without the chroma effect even more.

I'm not really sensitive to post-processing effects like Chromatic Abberation, Motion Blur, Bloom, or DOF. I love all post-processing effects. Hell, I bought this gaming computer so I could see all of those effects and still maintain a great framerate, however, I think when developers implement post-processing effects, they should always have individual check boxes for each one instead of lumping them into presets so sensitive users can tune the game to their liking without sacrificing other things like texture or model quality.

Great guide my friend
