Complete system lockup loading/running sample project
TLDR: This model of macbook seems to be faulty in the GPU/gpu drivers department. If other users also report this problem, consider blacklisting this model and throwing up a warning dialog to save other users from an unexpected lockup.
Steps to reproduce (I’ve done this twice, and both times had to force shutdown the machine):
Launch UE 4.8.1 via Epic Games Launcher.
Load advanced vehicle sample project (scalable graphics, targeting desktops).
System will lock within a few seconds, or (in my second test) after attempting to run the game.
On the first occasion, the viewer window originally appeared to render the scene, but soon displayed blocky black and white noise. After that the machine became effectively unresponsive, and I resorted to crashing it after 25 minutes.
UE version: 4.8.1
OS: Osx 10.10.3
Model: MacbookPro6,2 (mid 2010)
Gpu: Nvidia Geforce 330m GT w/ 512MB vram (hybrid configuration, and seemingly the cause of many of the problems)
CPU: First gen i7, hyper-threaded dual core 2.66Ghz
8GB ram.
Other notes: running aftermarket kingston ssd, upgraded to 8gb ram, usb hub and mouse attached. Running on AC power. Running editor on external screen. F.Lux colour tinter was running - not that it’s ever appeared to make much difference with other similar problems.
I’m inclined to blame osx and the gpu drivers for this one. The machine demonstrates minor graphical glitches in a number of other contexts. Small chunks of rendered content on webpages will sometimes jump out of alignment and back in. Nuke (from The Foundry) crashed regularly and displayed numerous graphical glitches before doing so. This would be the first time I remember a gpu issue actually locking up the machine mind you.
