I am testing the MAC client.
Initial things I noticed are that my FPS are:
lower than with the older one (~19-25 compared to 49 with the older version),
needs debug so it's not black every time I start it (at high quality the FPS drop even more),
thermal serp sword looks like normal serp when worn (looks fine in storage and inventory),
and there are no leaves on the trees at all (not sure about bushes).
I hope that was helpfull
