Now, this is not bannable but keep in mind to edit your game files at your own risk. This should fix your antialiasing-related FPS drops and make your game look squeaky clean again.

1. You're going to want to get to the engine.ini file. The file should be located under C: \ Users \ Your Account Name HERE \ AppData \ Local \ DeadByDaylight \ Saved \ Config \ WindowsNoEditor

2. After you've reached this location open the engine.ini file and paste the following lines in;

[/script/engine.rendereroverridesettings]

r.DefaultFeature.AntiAliasing=0

3. Save the file. ggez.

Additional Information
An ini file is just a config file, where various game settings are stored (graphics quality, mouse sensitivity, that kind of thing). It is human-readable and editable, and no reasonable developer would ever try to ban a user over editing such a file, since there's no way to cheat here. In fact, the only reason this particular ini file (WindowsNoEditor) ever comes up is because you can manually tweak certain settings -- such as frame rate and anti-aliasing.

Before and afters
Upon request I've decided to add a before and after photo section for reference, quality may differ for each of you though, some may be experiencing worse quality than this but this was my experience and enough to make me disable AA. Everything from character models, to obstacles looks horrible for me with AA enabled. These screenshots alone don't even begin to reflect how horrible it looks in game. You have ZERO visibility as killer or survivor, and can no longer see clearly a few meters in front of you, and auras look like complete blobs.

I would have taken more photos but I refuse to subject myself to motion sickness anymore, for my own health :') BUT IF ANYONE HAS ANY REFERENCE PHOTOS THAT REPRESENT THIS ISSUE FEEL FREE TO SEND THEM TO ME, AND I WILL ADD YOUR BEFORE/AFTER PHOTOS BELOW!

Left = Before I disabled AA (blurry)
Right = After I disabled AA (clear)
Top = Before I disabled AA (blurry)
Bottom = After I disabled AA (clear)

Totems, two different angles here, but holy ♥♥♥♥ ew.

1. Does this actually work?
Yes. This can actually work for you, so long as you correctly input the information directed by this guide. On another note, it's probably a good idea to keep in mind that, this doesn't work for everyone, and I've seen a few players saying that this just made their game look worse, in which case, just revert the changes you have made.

2. What can I do if this doesn't work?
I know of one other option, some people have fixed the blurriness by adjusting the resolution in-game. However, if I come across any other possible fixes, I will add them here.

3.Have the devs said this was okay or safe to do?

Peanits addressed this subject a long time ago. As he states, disabling antialiasing should be fine, and if anything were to change about that in the future, all you'd have to do is revert the changes you made to disable it.


What if I edit the wrong file, or make a mistake?
Please Don't. Double check everything just to be sure you're doing everything correctly. Don't mess with ANYTHING else, while ini. files are normally fine, I strongly can't recommend you messing with any other file but the one specified in the guide. If you do so, do it at your own risk. Also, it should be clear that anything that gives you a competitive advantage over another player in any shape or form is not allowed (as shown above).

I have more questions, can I message you directly?
Yes. Comment on my profile or request me and I'll get back to you and answer your questions.
