I’m having the same experience as quorra.4391. I never had crashes before HOT, and now they are frequent. At first, I only experienced crashes while in HOT maps (e.g., Verdant Brink) However, since the patch a couple of days ago, the game crashes in all PVE and PVP maps, and usually at the worst possible time (i.e. I lose out on rewards, chests, and participation that I’ve accumulated)
I then installed the 64bit beta client a couple of days ago, since some posters and players have reported no crashes since switching. However, the 64 bit client has made no difference . I play on an Alienware system with 32GB of RAM and dual NVidia GTX 780M graphics cards with 4GB of memory. I should not be getting out of memory crashes, and yet I am. Please fix this soon.
