macOS High Sierra
Just a warning for Mac users - the game doesn't work well in High Sierra. I haven't been able to play a game without major glitches and freezes during beta testing and it's still not fixed in the final public release. There are reports that the Unity Engine does not work well in High Sierra.

Do you have a discrete video card or integrated Intel graphics?

MBP with integrated NVIDIA GeForce GT 750M 2048 MB.

C:S version 1.9.0-f5

just another data point.

Make sure you system is actually using the GT 750m. Sometimes it tries to use integrated Intel graphics instead.

Monday CO posted on the Paradox forum that a new version of the Unity engine is in QA but no estimate when it will be available.

The game is using Metal API currently, you can force it back to OpenGL with the boot flags:


OpenGL Standard: -force-glcore
OpenGL 4.1 Core Profie: -force-glcore41
Fallback OpenGL 2.1: -force-opengl

I finally had to restore my Mac back to BEFORE High Sierra - Apple was no help - nor was Nvidia - it just doesn't work. Back to Sierra - and all is well.

Today's update should have fixed everything. lol

Can anyone confirm that the game works in High Sierra without any bootflags?

Update did not help me - still at 19 - 21 FPS

That sounds normal to me.

Played for about 10 minutes. I didn't see any graphic glitches but the game performance is still lower than it used to be. There is a 3-5 second lag on most things.

the game is suddenly extremely slow

Mine is working fine. It's High Sierra V 10.13.1 13 inch retina display late 2012.

You may wish to check mods to see whether there's any incompatibility issue there.

Game performance is not impressive but that has been the case for me all along. Sometimes I lose control of the mouse, sometimes zoom works more than I want, in other words some stuff here and there but for a late 2012 machine with 8GB RAM and several mods as well as some 850 assets, together with several themes, I think this is as good as it gets for me at least.

The thing is, with each new release some MAC issues appear, then they stabilize and vanish.

installed High Sierra today and the game is ridiculously slow. After I quit the game, all apps using graphics also have speed problems (Browsers...) really annoying

I'm using a late 2013 27" iMac with 24GB RAM
2GB Nvidia GTX 775M
3.5 GHz Core i7
1.1 TB Fusion Drive

I had planned to play the game between xmas an new years eve :(

Isn't there anything I can do?



UPDATE:
using OSX 10.13.2 (17C88) - High Sierra
Game Launch Option:
-Force-OpenGL
has improved the speed back to almost original speed

@Akeela: I don't have any PC anymore

Play on a PC until Apple fixes the problem.
