After update(new sky) OSX has terrible FPS

My mac used to play rust not all that good but it was fine. I hoped and saw that on trello the issue concerning slow FPS on OSX was fixed…
But after the new update my FPS is much more lower then ever!

Does anyone has the same problems?

bump!

can anyone tell me IF they are playing in OSX and it is running smooth, which version they have?

It actually doubled my FPS. I’m getting about 60 now… On 10.8.5
