How to reset resolution without entering the game?

I accidentaly changed my resolution to the lowest there is and now I can't get into the game, I just see a black screen.

Is there anyway to set the resolution to default (maybe a file that can be deleted to set everything to default)?

Solution 1:

This thread suggests that you may need to remove the options.dopt file from within your Steam userdata location - this will be in the folder that you installed Steam into and then the following;

Steam install folder\userdata\[id#]\50650\remote\options.dopt

Backup this file to another location and remove it from this folder, and the game should then start with a default set of settings, including default resolution.

If you are not using Steam, search your computer for options.dopt and then move this file temporarily to another a location to test this resolves your issue.
