Dunno whats going on but no one knows how to run it higher than or as equal as the youtube video shows.

The game supports these resolutions:

800x600
1024x768
1280x720
1280x1024
1366x768
1440x900
1600x900
1680x1050
1920x1080
1920x1200
2560x1440
2560x1600

If you can't select one of them then it's because the game isn't getting data from.. wherever it gets it, that your monitor supports the resolution.

In your case, you're not getting 1366x768 because of your native res being 1360x768. My monitor only has native support for 1360x768, so I can't select 1366x768 ingame either.

I tried setting a custom resolution of one I couldn't select (2560x1440) but it didn't appear in game.

It's possible the EDID data is read directly; I'll have to play around with powerstrip and see what I can do..
