Generally quite a nice update, especially the new wake effects look great even if the movements of the water seem too fast and not related to the ships speed, especially at the bow. The new placement of the info tab revealed by pressing "H" is difficult and now conceals ships speed and depending on situation possibly islands and other obstacles that could be avoided if it was in its old position. Also the information displayed on it is difficult to find quickly and in some cases just seems plain wrong. One major issue with the info tab is that it appears when pressing "H" even when typing in chat, which is really annoying.
This maybe the wrong place for this, but after about 6-9 games the frame rates drop drastically (from 70-80 down to around 25-35) making the game unplayable, restarting game client resolves the issue, hence it is not something to do with hardware or graphics card drivers.
