Actually i play the game on a 40' screen 3840*2160 res
( no i can't use the usual 1920*1080 cause my screen is way too big , mean it will be tiny )
Even with the lower UI scale option my UI is waaaay too big but i can deal with that ~
The main prob is when i try to open the cash shop i can't even click on items , i have to pull out my cursor at 4-5 cm from the desired area i want to click to make it work , check the gif it's really weird .
( i find a way to put my personal res btw , by editing the general.ini file and put the number i want but it's still big sadly )
