Tips and tricks:
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.
Run the game in a borderless window: Use the aptly-named Borderless Gaming program. See here for a usage guide.
Note: You can purchase the program on Steam for USD$4 or your regional equivalent if you're feeling charitable.

Enable VR mode: Append -vr to the launch options/target line field (see "Set a custom/>1080p resolution" for instructions on how to access the launch options/target line). (Credit to Tain.)
Note: VR mode is, as you might expect, very demanding; a slightly customised low settings configuration is recommended for a 970 and GPUs of similar power. (Credit to Durante.)
