Playing on 64 bit is much better than previously, and thanks for bringing game to this era - better overall game performance - however the bugs:

Camels & player's cat mounts:


After transformation into Werewolf:


Missing faces of random NPCs:


Naked female cats:


And humans:


Also strange stuck - allows me to find holes in wall inside Sandblown Mine in Alik'r Desert - when I use the skill to rush to enemy who stands close to a wall.
This chessboard like dimension is quite interesting, just a pity it's cubic, not endless and has a bottom - checked with painful death - curious was I could respawn at the bottom and run there a bit:








Also in this mine are areas where spiders sometimes stuck in walls, so this whole mine seems leaky:


I almost forgot - that mine was also "haunted" by those annoying hissing sounds.
Please check that mine because is there!

As for the crashing, I noticed that ESO is somehow more sensible if I log into game some time after another game (no matter the time from last game). But after last patch it's quite stable when logged in from fresh PC start or restart. I get no crashes (knock knock) when my PC is fresh, when I encountered few crashes after eg. playing CS:GO, quitting and logging to ESO after few minutes.

PC config:
i5-3570@3.40, 8 GB, Asus GTX 660 Ti, Standard HDD320GB and cable internet
