I do my primary development on a Late 2013 and on a Six-Core Nehalem desktop machine running Windows 8. Both machines have powerful GPUs and CPUs, and UE4 works like a dream.
However, sometimes I like to work on my laptop. Early on, UE (4.1, 4.2) was basically unusable on my Mid-2012 MacBook Pro. The last couple of releases, especially running under Yosemite, Mac performance has improved tremendously and I’ve been able to do productive work on my laptop.
However, the current release (4.4.3), I’m having huge problems with animation when I run on my laptop. Sometimes characters will animate. Sometimes they’ll animate at a very very slow frame rate (like 1 frame every 3 or 4 seconds). Mostly, they’ll just move around in the idle position. Sometimes portions of the character will bulge upward, usually the back/torso area. Characters controlled by AI characters suffer the same fate, but also MoveTo often doesn’t work. Sometimes they will animate but not move, sometimes they’ll move but not animate, sometimes they’ll move a little ways and then get stuck.
I’ve turned off GPU switching so that it always uses the discrete GPU. Running in separate window or as standalone game doesn’t seem to help.
Any thoughts on settings I could change to reduce or eliminate this problem would be greatly appreciated.
