Why do packaged games for Mac run so slow?

I’m getting started with Unreal Engine and I packaged a third person template project for Mac.

I did run it in a Macbook Pro from 2014 and it is extremely slow. Absolutely unplayable. Very low frame rate and the controls react 2 or 3 seconds after they are triggered.

Has anyone of you faced this situation? How have you solved it? Thanks

I run it on a Macbook Pro Retina:
Retina, 15-inch, Late 2013
Processor 2.3 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 750M 2048 MB
Serial Number C02M455MFD57
Software OS X 10.9.5 (13F1077)

I also tried by unchecking all post-procesing effects in the render section of the project settings and the build still runs very slow.

Any help would be appreciated,

Check if Intel is not turning on as rendering GPU, also how much fps you get as “slow” is relative :stuck_out_tongue:

Hi, thanks for your reply! I’ve reviewed in the preferences and in Plugin-Graphics section, the Renderer ID is set to the graphics card, not the Intel processor.

The game runs smoothly in the engine editor, where it runs slow is in the Mac build, so maybe I’m missing another setting for the graphics renderer specific to the builds?

About FPS I don’t know how to get the exact value but I think it is between 20 and 30 by eye.

I also checked the Open GL version that the computer is running and it is 4.1

I haven’t been able to solve the problem, but I downloaded and run Unreal Tournament and it runs beautifully smooth in the same machine, so it must be a problem of packaging or project settings.

Found the solution!
