Ok, when it starts for the first time, it boots at 1024x768. This can be changed by editing one of the config files (I forget which one, but it was easy to find). The ingame video options has a LOT of resolutions, though I didn't look for 1280x720 since I don't use that rez. But, it did have 856x480 and 1920x1080 which I use, so I bet it does offer 1280x720. Once you have either edited the config file or changed resolutions via the ingame video options, it boots to that rez from then on out.
