Druid looks nice, I just played through the Nautiloid to the Beach. Lip sync was a little better, though Lae'zel is still zipper lip'd during the flip the switch dialogue. Cinematics looks a little cleaner, still some chop but smoother than before, and the crash looks better at night. Double shadowheart at the door is gone, but she still had the zipper lip for line there.
What changed about the UI? I can't tell any major differences from patch 3.
Hotbar still unlocking automatically after reload, just noticed after first save out. I don't note the cursor delay for the hotbar as much, though its still same bar for everything (no separate spellbar yet) but inventory cursor delay still going on.
Camera control feels basically the same, Z axis still locked.
I have kind of given up on trying to enjoy the ISO cam, and just play it in driving view max zoom-in as much as possible.
Least we have something to play around with now though
