Hey guys! Just thought I would share some information with those of you that are on OS X running UE4.
I have a Mac Pro 1,1 tower with dual Quad Xeons 2.66 and 32GB DDR2(yeah, I know) and a Radeon 5770. As you may already know, this is well below UE4 min specs. I was running Yosemite 10.10.5 for the last few months and UE4 was barely playable, even on low settings in the demo scenes provided with the engine. However, I’ve recently upgraded to El Capitan and WOW is there a huge difference. Not only is it playable, but I’m running 30+ FPS on Epic engine settings. Highly recommended for those of you on an older Mac.
Tonight, I’ll be replacing the 5770 with a GTX 560Ti and updating this thread.
Edit: this model Mac Pro is from 2006 and was purchased for only $200 + $100 for the 32GB RAM kit on Amazon and CPU upgraded from 2 dual-cores to 2 quad-cores. The 560Ti is going to run me a whopping $50. That puts me at $350 for a PC that runs unreal smoothly on high settings(in a decently put together project), can run OS X/Linux/Windows, can run all my music apps(Logic, Pro Tools, etc.), and can build all general Apple applications. I’d say this is a pretty sweet deal if you have the know how.
