i recently upgraded my OS to windows 10 because i had issues with windows 8.1(which was shit anyways but stuff like dota worked fine).after that i installed wc3, new installer, patch, etc...and its all fine, i can enter the server and game, but it all laggs like hell, i have spikes even in menu of wc3.its so shitty that i even wont join games.does anyone know the reason or have some idea how i can fix this?
