Znalazłem takie coś przy poszukiwania crasha w sterowniku:
"there some driver bug that's been around since driver version 6.14, driver support i think it is, and ATI never fixed it because, well, not everybody plays wurm.... i use omega driver 6.14 to fix this, i would recommend everybody else to as well, and CCC is a waste of time, the CC you get with the omega drivers is much more customizable and not overruled by the AI... if this doesn't fix the problem, I've no idea what will."
Cały wątek jest o problemach ze sterownikami ATI przy dużej ilości tekstur co pasuje do naszej sytuacji. Spróbujesz zainstalować drivery Omega?
