I would love a 21x9 UI for 1512x648 resolution. I've found that Icewind Dale 2 will run at this resolution via the widescreen mod as long as you create a custom resolution in the Nvidia control panel. Not sure how it works on AMD. I've been playing IW2 successfully on 1512x648 and 1680x720. These resolutions allow you to use your entire Ultrawide without being super zoomed out. Is it too much to ask for a custom UI for 1512x648? I've tried doing it myself via Near Infinity, and got as far as editing the MOS files, but in game it still would not work.
