Alien Isolation has some wonderful graphics and performance right out of the box. The graphics options themselves lead you to believe the far right choices are the highest quality, but this is not true.
In this article, you can see the difference between the best 2 forms of anti-aliasing.
Notice that the option “SMAA-T1x” is on the far right, but if you go left one option, you get “SMAA-T2x.”
Looking at the side-by-side comparison, SMAA-T2x is the better graphics option. The performance hit is probably not going to be noticed at all.
SMAA-T1x (Enhanced Subpixel Morphological Antialiasing) is like the older version of AA known as FXAA, which probably doesnt mean much to you, but it means less blur.
SMAA-T2x improves on 1x and uses a technique called “Temporal Anti-Aliasing,” which sounds like time travel, but results in the better picture above.
The atmosphere, lighting, particle effects, textures, and frame rate in this game are top notch. Finally, an Aliens game worth of the franchise. Although, for a hermetically sealed space station, there sure is a lot of dust falling everywhere when things explode and collapse.
Solid Tip: If you run multiple GPUs, SMAA-T2x is not compatible with your configuration. Stick with T1x if that is the case.
