Hey Im trying to play offline just with bots just to practice and my pc is already kinda of heavy so I dont have steam either.But I am getting weird errors, like sometimes when Im playing with bots the screen freezes and the game keeps frozen till I press ctrl alt del and close it.It'd normally happen when I'd cast a large spell,the same spell several times or when I'd cast a spell too close to someone.And when someone goes on with me I cant even see this person hittin me all I see is this black screen and everything goes back to normal when the melee sequence ends.
