AMD R9 390 Freezing Issue

[Raist]

Did you make sure your PSU was up to the task? That 390 can consume more than double that of the 760 under full loads--saw some tests tracking peaks exceeding 400 watts even. That is just for the graphics...in addition to the consumption of over devices on the PCI-E bus, memory, CPU, drives, USB, cooling...

Need a pretty strong and stable power supply to run that card with all subsystems full throttle like this game will do because it isn't optimized as well as many other games out there these days.

The crashing after 30 minutes sounds kind of like the old memory management problem in the drivers. May be able to mitigate it somewhat with things that reduce the memory usage--textures, LOD stream cache, etc.
