Notes Using Mac OS Catalina 10.15.6 on 3GHz 6 cores i6 and 32GB DDR4
I am a beginner with Unity game development but not in development. I would like to use this project as a starter to learn and try. Could someone tell me if it is possible to reduce the memory usage of this project so it can be adaptated to a lighter game ?
Thanks for the issue report, @mushu8! Did you try and check why the game lags? It would be great to know. You could try and use the profiler? Since you mention you are a beginner with Unity, this talk might come in handy.
You might also have to rebuild the app for Mac using "Development Build", so that you can attach to it and profile:
If the task is outside of your knowledge don't worry, we will do it (as we get some time) or hopefully another member of the community.
I tried to google this MacOS specific performance issue and came across this log from Unity Answers: https://answers.unity.com/questions/1695529/is-it-expected-to-see-worse-performance-on-mac-osx.html
It might be some thing to retrofit in 2019.x LTS or we wait for 2020.x LTS version to get this solved...
this MacOS specific performance issue
Hmm, I'm not specific if you're talking about the issue @mushu8 is describing? Sounds to me like a framerate issue, more than specifically on the input. But I'm not too sure.
While I understood how to create the development build and attach to it for profiling from the video, not familiar enough with the codebase to figure out why the PlayerLoop in each frame hovers from 14.5-19ms per frame. Is there an easy way to share my profile data for someone else to review so that they don't have to build? I'm on MacOS Big Sur 11.12.3 with 2.9GHz 6-core i9 with 32GB DDR4.

Hey, yes, the Profiler has a Saving functionality, you can export a file and share it here so we can take a look. Could be useful and fun for learning too!
Thanks!
That's what I did the other day, but when I tried to upload it here, GitHub said the file type (.data) wasn't supported. My brain was so fried that I didn't realize I could convert it to .gz using gzip and upload it, so I'm trying that now and the file (~41MB) is too big (needs to be <10MB)! Guess it'll be for personal edification after all, heh.
I guess you can link it using Google Drive, or Dropbox, or similar? (if you want to)
Been so swamped lately that have only now gotten a chance to update to the latest code and re-profile, so here's a Dropbox link to a ZIP file of me starting the game on the beach, taking a few steps, attacking the air a few times, and jumping.
