Act 3 cruel drowned city crashes the game to desktop, high prio

I entered drowned city in act 3 cruel, and as soon as my char was able to move it started slowing down the framerate to a standstill follow by the entire aplication quitting to desktop.

It happened again after reloging, character takes no more than a few steps before the entire application freeses up.

This issue has not occured for me in any area leading up to drowned city.

Ill play some LE in the meantime, as this issue is gamebreaking and hinderes progression entirely.

Maybe the 15 min reset will work, but aint nobody got time for that.

So tested again, the game still crashes. I managed to walk what im asuming is a few tiles, about half a screen to one side, then it imidiately lagged and crashed to desktop.

Maybe there is some issue when loading in terrain in the drowned city.

Please investigate as the game remains unplayable.
