I have done lots of good searching and there are about 10 threads and not one has a solution. What are you hiding Riot?
Like I said I get negative percentages for players on loading screen. After I load in, the game is unplayable. My character moves across the map in 3 seconds but teleports back to the correct position. Framerate never goes above 25FPS which is impossible for my hardware. I have tweaked every in-game setting, checked any firewall, tried disabling cpu cores, repaired and restarted computer multiple times, checked AMD Control Center to see if graphics card settings were interfering, made sure gpu drivers and all drivers were up-to-date. Sounds like i'm **** out of luck?
