Tips and tricks:
Various CPU/GPU benchmarks and data: See this GameGPU article.
Note: The article is in Russian, but the data is presented via graphs.
Cap the framerate/potentially improve frametimes: Download RivaTuner Statistics Server, input your desired framerate limit in the "Framerate limit" box, and hit enter (the program comes bundled with MSI Afterburner and earlier versions of EVGA PrecisionX). Alternatively, those with an Nvidia GPU have the option of Nvidia Inspector, which can also be used to impose a framerate cap, either in a similar manner to RTSS or by way of forcing a different vsync interval (click the small tool icon to open the game profile section).
Note: Useful if you your system can't maintain, say, 60fps and you're sensitive to the wild fluctuations, or you're experiencing uneven frametimes. The greater window the engine has to render a given frame, if you're imposing a lower framerate than the game can otherwise provide, may also help in alleviating stuttering related to data streaming.
Stop the game from crashing after 15 minutes on touch-capable systems running Windows 10: Open the task manager, switch to the Services tab and disable TabletInputService.
Proper 21:9 support: Open C:\Users\[username]\Documents\My Games\XCOM2\XComGame\Config\XComEngine.ini and change AspectRatioAxisConstraint=AspectRatio_MaintainXFOV to AspectRatioAxisConstraint=AspectRatio_MaintainYFOV. (Credit to Human_me.)
Improve performance: Lowering the "Decals" setting may notably improve the framerate when in base view. (Credit to LurkerPrime.) Additionally, have a read of RPS' performance guide. (Credit to SalsaShark.)
Mitigate stuttering: See the "Fix stuttering" section of this guide. (Credit to reyqune @ Steam Community via CynicalBastard.)
Shorten post-mission load times: Hit the caps lock key during the loading screen. (Credit to someone @ Reddit via MonorailCat.)
Skip intro videos: Right-click on the game in your Steam library -> Properties -> Set launch options... -> Input -nostartupmovies. (Credit to someone @ PCGamingWiki.)
