I started an episode of multiple crashes after playing about an hour. I tallied 9 crashes.
I then found this:
I know it sounds cheesy, but I run 64 bit and have tried all sorts of potential fixes. So, far. I have not crashed once.
I've stood in one position until it logs me off, I have run dailies where I was just constantly crashing. Especially the Gree dailies (Ilum)
Give it a try. I will let you know if my stability continues.
Not sure this will fix 32 bit. I still believe there is some sort of memory leak issue there.
Now I play Windowed mode as well.
On a side note: My game startup and loading time seems much faster too.
