Ok so closed most apps ran game watched the overlay ram monitor. Not running any apps, it displays 3189MB memory. When in game it shows last 2689 MB before crash.
I assume this is remaining amount of RAM.
Managed to play 1 story mode with no problems. Then crash with this log.
Code:
Could not allocate memory: System out of memory!
Trying to allocate: 4194304B with 16 alignment. MemoryLabel: GfxDevice
