Can you add a settings menu pre game for those with weaker PC's? Pausing on a low-tier PC in-game causes the graphics driver to crash.
It has been suggested a time or two in the suggestion megapost - As well as defaulting the options to low/off
The suggestion for defaulting to low has been responded to personally by the dev, saying that he plans to lower the default settings.

For the time being however if you can't get to the options in game
you could try getting into the settings file with notepad ++ or a hex editor (seems there's a hex editor addon for notepad ++... not sure, there's another thread showing an image of theirs)
