The new 88 update made fullscreen mode unplayable (framerate is extremely rough.) In addition to of course multiple other new issues related to the resolution and/ or client window.
i 2nd this. i was changing my physical display resolution settings and was getting almost full screen windowed. now its fixed to that little tiny window no matter what i do. my computer resolution continues to change but the game size stays the same.. im not sure what was changed but reinstalled game and everything but no luck. been trying for a few hours..
* I have a workaround for the time-being: keep the game [windowed] and change your desktop resolution (I did this in nvidia c.panel) to 1600x900. This enlarges MapleRoyals window to nearly fullscreen for me + game stays super smooth
when I enter full screen my windows bar is still at the bottom of the screen I cant see my hp bar or anything, sometimes i cant Alt + enter.
