I use a 28inch monitor at 4k resolution. While game UI scales perfectly there are 2 things that don’t.
1st Is the in game mouse cursor that I believe is a well known issue, and maybe, I say maybe isn’t that easy to fix, BUT the 2nd one…
Is at least pity to see the launcher and the login popup window not scaling to 4k resolutions (or any other than it’s standard) and need a magnifier to read what it shows. And this I believe is an Easy Issue to Fix.
