This setting affects the presence and quality of various light sources in a given scene. Low offers minimal lighting; Medium offers slightly more detail and higher fidelity lighting throughout the scene; High offers more detail and fidelity while introducing sun rays; Ultra brings the sharpest possible lighting throughout the scene.
The benchmark tells us Lighting Quality has no significant impact on framerate and as such, most should be fine to enjoy the benefits of Ultra.
This ever important option controls the appearance of jagged edges (jaggies) seen on various surfaces throughout the game.
Off, distracting aliasing can be observed most noticeably on the beige building in front of Bastion and on the top of the middle building in the distance; FXAA eliminates most aliasing, although it can still be seen on top of the beige building and on Bastion's gun; SMAA Low reduces the aliasing on the gun; SMAA Medium eliminates it completely as well as the aliasing on top of the beige building; no difference is observed between SMAA Medium and SMAA High.
Testing says there is a small but steady hit to framerate as this setting is increased, with the exception of SMAA High, which has no effect (in line with visual results). If you're looking to increase your framerate but don't want distracting aliasing in your face, FXAA offers a nice balance. Otherwise, you're probably best off with SMAA Medium or SMAA High. And of course, if you're desperate, disable it entirely for an extra few frames over FXAA.
Adjusts the quality of light when it bends as it passes through specific types of objects (such as translucent objects, to name one type). This one is extremely difficult to observe in game, but I did capture a decent example in the screens here, which show not strictly better changes in the left windowsill and the lit object above the door on the right.
Benchmarking reveals this setting 3-4 extra frames when switching to the Low setting. Given that, how rare it is, and how it's difficult to argue the results are better when increasing it, Low is strongly recommended.
