New MacBook Pro 2017. KSP totally umplayble due to lag and stuttering.

[Apartment_Panda]

I used to play ksp religiously on my MacBook Pro 2013 model. Worked fine in orbit, always suffered low FPS on launch but I just suffered through it. Ksp is worth it.

Wanted to jump back into some KSP, however the game is unplayable on my new 2017 MacBook Pro. The game stutteres and the menues barely work. What’s going on? Laptop is brand new and I have installed no mods, so it’s nothing to do with the game at my end.

 

Is there a patch planned in the near future?

Known concerns and a handful of possible workarounds with KSP on High Sierra are documented in this thread. 

As well as those suggestions, if you're on a 15" MacBook Pro, it may be worth trying to force using the higher-performance discrete graphics card.

EDIT: I've just gotten home and tried running the game on my 13" 2017 MacBook Pro, that I picked up from the store a week ago. Running the game with the default settings was horrible, getting the same stuttering and lag all through. I was able to launch a Kerbal X, but it was a slideshow.

Added the `-force-opengl` argument, and it seems a lot smoother. Launched a Kerbal X, in a new sandbox game, with all default settings. The MET timer flickered between green and yellow a fair bit, but the game ran smoothly all the way to orbit.
