So the game does not play nice with the windows DPI setting. For a while after setting it as 4K and playing a bit. I was thinking there is some duff scaling going on it looks 1080p or like the setting in the launcher is ignored.
Had a reddit search and found that only by changing the windows 10 text size change for the whole machine back to 100% does the game run in the correct resolution. (I expect it was upscaling then downscaling).
It makes my system almost unusable (the text is too small to read on a 4k monitor). And a pain to change every time I login, then back. But wowsers it makes a difference. No blurry UI or Text, pin sharp resolution running as it was set in the launcher.
Is this going to get fixed for launch? It seems like a really strange massive basic bug to be getting wrong this late in the game.
