This is my machine:
iMac (Retina 5K, 27-inch, Late 2015)
3.2 GHz Intel Core i5
32 GB 1867 MHz DDR3
AMD Radeon R9 M380 2048 MB
All I can say is the engine runs like rubbish on it, so I'm flat out astonished to hear it runs 'very well' on your 2012 macbook.
This is the compile time for running a 'hello world' project with a few tests:
[2016.03.20-09.44.43:606][ 0]Log file open, 03/20/16 17:44:43
[2016.03.20-09.44.53:841][261]Display: Running Automation: 'NppTests' (Class Name: 'FNppTests')

real 6m47.566s
user 3m58.869s
sys 0m41.303s
That's not a full rebuild, just running:
./Engine/Build/BatchFiles/Mac/Build.sh TestProjectEditor Mac Development TestProject.uproject
UnrealEngine/Engine/Binaries/Mac/UE4Editor.app/Contents/MacOS/UE4Editor TestProject.uproject -Game -ExecCmds="Automation RunTests TestProject" -unattended -nopause -testexit="Automation Test Queue Empty" -log="TestResults.txt"
ie. It's only compiling the local project files and relinking the engine files. That takes 7 minutes.
With the quality settings dialed back completely, games are... kind of playable.
This doesn't match your experience?
I'm deeply deeply interested to know what you're doing, because it doesn't run like you describe on any apple device I've ever used.
What engine version?
Did you build it yourself? Which branch are you running? Did you change any of the build settings?
What quality settings are you using?
Seriously, I'm not trolling. If there's a magic 'make this actually work' setting some where I'm missing, I want to know about it, because the engine is monstrously slow in my experience, unless you're running it on a windows machine.
My recommendation for people using UE is 'dont use a mac'; I've never once varied from that position in the last year, I'm really interested if you have a different experience.
- pmoriarty 11y agoMy experience mirrors yours. I have a high-end Mac laptop, 16 gigs of memory, 1 TB SSD drive. Unreal Engine runs like total garbage on it. Moving around in a simple scene is incredibly slow and painful. Their keyboard controls are also pretty confusing and awful. I'd really like them to support something like the 3Dconnexion mouse[1], which would at least make moving around intuitive and easy, but it doesn't.[2] [1] - http://www.amazon.com/3Dconnexion-3DX-700028-SpaceNavigator-3D-Mouse/dp/B000LB7G00/ref=sr_1_cc_1 http://www.amazon.com/3Dconnexion-3DX-700028-SpaceNavigator-...

- iamcreasy 11y agoWould I be wrong to say Apple doesn't prioritize GPU performance. Ergo, for game development it's undoubtedly safer to buy non-apple brand machines?
- jaegerpicker 11y agoyes you would be wrong I have the same model and the hello world example runs WAY faster. I'm not sure how to explain the difference but I do not believe it's an issue with apple.
- jaegerpicker 11y agoI have a MacBook Pro mid-2015 2.5 i7 16GB Ram 1tb ssd AMD Radeon R9 M370x. Here are my compile times for a non trivial game set to maximum settings. Literally straight up standard download from Epic version 4.10.4. Building the game itself: Total build time: 20.36 seconds Not quite a exact same test as yours but I've honestly never used the engine in the way you are compiling it there. I understand it's a basic compile and execute tests but I usually run my tests via xcode and build/launch the game from either xcode or the unreal editor both are very fast.
- shadowmint 11y agoDoes that include relaunching the editor? (tests obviously are not supported for hot reload)
- jaegerpicker 11y agoThat's the compile time for the game only launching the game editor takes an additional Full Startup: 12.02 seconds (BP compile: 0.17 seconds) according to the unreal engine logs. It feels a little longer than that but not much. I'm always honestly a little surprised but that Java webapps we have at my day job take a lot longer to compile and launch than Unreal does in my experience. I will say to be fair in Windows 10 on the same hardware (bootcamp dual boot) Unreal is at least twice as fast. It's kinda crazy and bums me out a bit.
- shadowmint 11y agoInteresting. Out of curiosity, what proportion of your game code is blueprint vs. C++? Mine would be probably 80/20 in favour of C++; I wonder if using C++ heavily has a disproportional effect on the editor speed somehow. Certainly sounds like you're having a much better time of it than I am...
- jaegerpicker 11y agoMostly C++, probably a 80/20 split or so also. Two other things, I've noticed that performance has improved greatly over the last couple of releases and my older MacBook pro (2012 model, 1gb nvidia gpu) wasn't nearly as good. I wonder if it's a case of Epic really only testing on certain Mac Laptops? Not sure I'd still use the engine if I was getting your level of performance on my machine.
- larryweya 11y agoPerhaps very well was an overstatment, it runs well enough to use on OSX, I always build from source and I've just done a fresh build of 4.11 on El-Capitan. Build took about an hour. Initial build of the FPS template takes about 90 seconds and runs at an average FPS of 30-35. The Blueprints template runs at about 15fps at Epic setting and about 20-25fps on high. For scenes like this, I set the engine scalability to high or medium and material quality to medium. I often work from within Windows where it all runs better.
