I wish it could simply hook into the game, but the launch process of Steam titles makes it tricky. The only reason the mod hooks into Steam is so that it can then hook into the game as soon as it starts. I'm not particularly fond of that feature either. You are of course right that it seems a bit shady to inject into Steam, and that it might be a security risk. I will do some more testing on the Anniversary Edition update, thanks! :) Please let me know if it works for you, or ask away if you have any questions. The source code and binaries are on github: Ĭheck out for some comparisons between the built-in anti-aliasing solution and the mod, and the README for more details. The mod implements an algorithm similar to Unreal Engine 4, Uncharted 4, and Inside. This allows it to remove the shimmering of moving edges at a reasonable cost. Temporal anti-aliasing blends multiple frames together using a content-aware filter.
SMAA (Enhanced Subpixel Morphological Antialiasing) which shipped in the game isn't enough to remove the high intensity aliasing on edges of shiny surfaces, so there's crawlies everywhere in the game. The mod does all of its work in the memory of a running process, which means that no tinkering with the game's files is necessary.
It works by hooking subroutines in the game, injecting extra code, and replacing a few shaders. I wrote a mod for Alien: Isolation which adds temporal anti-aliasing.
