Performance issues on macOS
This game performs great on my Windows PC, but performance is sluggish on my Macbook Pro*—even with lowest resolution and lowest quality settings. I recorded some footage if that's useful 😄

Cheers, Lee 🍻
PS: I absolutely love this game!!!
What are your Windows PC specs? I don't think the issue is related to macOS necessary just poor optimization, I'll do some test and see if I can find the problem :)
My Windows PC is an aging MSI laptop ~
- Intel Core i7-4710HQ (2.5GHz, 6MB Cache)
- NVIDIA Geforce GTX980M with 8GB GDDR5 VRAM
- 32GB DDR3L 1600 MHz
Let me know if you need a hand testing 😁
Actually, I do. Since I don't have a Mac could you run this new version and tell me how the performance goes? Neon Skylines - Mac x86.zip
I definitely see an improvement, but it still jerky/laggy compared to the Windows version. Playing with the lowest quality settings is slightly better than player with the highest. Would it be helpful if I shared a video showing performance?
Yes, please do so I can compare it to the first one you showed me. The slight performance difference between the lowest and highest graphic settings must be because the game is CPU-bound
I've tried distributing some of the heavy chunk loading across frame which should in theory produce less jerkiness. Here is the new build can you tell me how it goes? Neon Skylines 1.0.2 - Mac Universal.zip
1.02 performance is much, much better - probably up to about 90% compared to how it handles in Windows. The graphics are completely different though - not sure if that's intentional? Here's some gameplay footage starting out with lowest quality settings then jumping to highest...
Getting close! 🤘
The graphics were definitely not intentional. This last build should be the golden one, it should fix the graphics and mantain the performance improvements. Thank you very much for your help in solving the issue. 😁 Neon Skylines 1.0.3 - Mac x86.zip
You're welcome! Thanks for fixing bugs reported by a random guy on the Internet!!!
The ship now flies super smoothly - at maximum resolution and quality! 🚀
There's still a little bit of jerkiness/stuttering, but on closer look it looks like the ship position/camera might be changing on the Y-axis. Perhaps as more things are coming into view?
GIF to illustrate below. The blue line is static - I believe the ship should always be level with it as long as W and S haven't been pressed..?
You are right, it should always be in level with the line. I suspect it's an interpolation issue and I took care of it on commit 25b01015f57065e4098216be364cef6ff63b3022. Here is the latest mac build Neon Skylines 1.0.3 - Mac x86.zip
Assuming that's the correct .zip file above (the previous file was also named 1.0.3) I don't think I see a noticeable difference at higher resolutions / quality? Here's some footage showing performance at 640x480 (very low quality), 1600x1200 (medium quality), and 2560x1440 (ultra quality).
Yes, It was the correct .zip . The build fixed some small jerkiness that was also in the windows build, I thought that was the problem but this to me seems more framerate related/physics timestep. Do you know what is your average framerate while playing? Do you notice big framedrops?
I'm not sure what the best way to give you accurate average framerate information is, but here's some more video footage showing gameplay and framerate windowed at 2560x1440 (high quality). Note: the mangled audio at the start is me messing up with the video capture.
Here's the ~short~ GIF version:
Please let me know if I can do something / provide anything better than that info. Is there some debugging info / logging you can sneak into a build that might be useful?
Sorry for the delay, here is a build with some debug info on the screen, it should let me know where the bottleneck is. Neon Skylines Debug 1.0 - Mac x86.zip
Hi @Zaphyk - here's some footage showing gameplay (i) 2560x1440 @ Ultra and (ii) 600x480 (Medium) with debugging info. Let me know if I can do anything else 🤘
Hey, someone suggested me a fix for this. I implemented it and here is the build. Let me know if it works. Neon Skylines 1.0.4 - Mac x86.zip
Hi - thanks @Zaphyk! I checked it out, but unfortunately I didn't notice any difference between it and the 1.0.3 version from https://github.com/Zaphyk/project-skylines/issues/3#issuecomment-345544072.
I'd like to also report having the same problem on macOS. The game looks good but it's unplayable at 800x600 on Very Low settings.
Same story here, I can confirm this on a new macbook pro running high sierra.
