Game crashing when using waypoints
Yep, I get it too, I think a fair amount of mid-end computers get the problem.
The cause, I’m not sure exactly, probably memory related.
I was getting this error frequently when I was running 32bit vista, it resolved itself when I upgraded to win8 64 bit. It’s a known issue (taken from another post): “There is indeed a known issue with Windows 32-bit operating systems and certain Nvidia cards, primarily the GTX cards. We’re still looking into this but at this time there is no ETA for a fix. Players with 32-bit operating systems would be limited to the lower graphics settings as this is meant to prevent the “Out of Memory” crashes.
So unless you are able to upgrade to a 64-bit operating system (and probably add a bit more RAM as well) I am in agreement that lowering some of the graphics options may lessen if not stop the Out of Memory crashes.”
