I haven't played this since I got my new 4k monitor since the GUI doesn't scale. I also cannot stream the game because of the same reason. This is something that, I believe, should have been addressed when it was first addressed over 4 years ago. Since scaling GUI is not an option and 2k and 4k monitors are becoming more popular DDO is being overlooked because it is really hard to play in higher resolutions. Another option would be to open DDO up to the steam workshop so players could fix this issue or allow for GUI mods.
