Turning off AA and turning shaders down to very high from extreme in dx10 is one of two things I tried today to alleviate the crashing I have. The other was to try a bladesmaster instead of a marksman after repeated reports of the shooting being a major contributor to the memory leak etc. I crashed once in 3 hours, yay i guess. It still looks very nice graphically.
The zombot idle animation almost made it worth the long wait to collect the parts alone
Many thanks to Steamrice for his post btw, it explained some stuff much better than the manual does!
Subscriptions were up for an hour or so earlier apparently but is down again atm.
