Ok so I've been getting this same issue over and over the past few days. The problem has gotten progressively worse happening more often till now it occurs every few minutes, making playing impossible.
Basically warband functions as per normal, till eventually without warning the game will freeze and switch between 2 or 3 frames over and over. The game will continue to run, sounds of the battlefield running normally, I am just stuck in the 2-3 frames looping. I will alt tab, then tab back in the game is then back to normal. After this happens 5 or 6 times, the game will crash. The game almost certainly crashes when the server switches map ( no idea if that is related)
ive uninstalled warband, crpg, and my GFX drivers(installed updated ones)
I'm at a loss, please help me!
