Two days ago (20/04/2021) , LoL starts having some FpS issues in my desktop so i go check out if theres any new update of the GPU software , in the next day (21/04/2021) I've already downloaded the new 21.4.1 driver and everything seemed fine till for no reason at all , the FPS ratio starts flickering and stuttering all of the sudden making it unplayable and the problem seems to appear after I start League and after I Alt+Tab in any circumstances . In the driver notes this is marked as a known issue but there isn't anything I can do to sove it , can anybody help me out in this situation with any sort of information pleaase ! Thanks !
