UI Minimized and Game Runs Extremely Slow

[Lantsubari]

I've been playing the game for a while on PC and was file earlier this morning. But I started tinkering around with the display settings just to see what Bordered Windowed, Fullscreen and the Higher resolution settings would look like. I always play in Windowed mode and I think the UI resolution is 100% at the Standard HD level. However when I started clicking on the different settings my UI started getting small so I clicked default to go back to how it was except it messed up the game even moreso. The UI is so small I can't even see it and when I tried to play in windowed mode it shrinks the game window down so that it's only encompassing part of my screen. When I maximize the window the frame rate crawls to about 8fps. I've tried tinkering with the settings and the best I can do is go full screen mode at 200% resolution. But things such as my cursor and all the text are huge as well as the game looks fuzzier. I tried uninstalling and reinstalling the game per the support chats instruction but it just came back to the wrong version as how I left it. Does anyone have an idea or can help?
