If a game is compiled in 64bit with 'IMAGE_FILE_LARGE_ADDRESS_AWARE set' then it has access to a maximum of 8TB of RAM with Windows Vista x64 and above. Having said that, very few games are encoded for 64bit and I'd be surprised if MechWarrior Online was one of them. More likely is that the extra memory improves performance by not taking it away from the operating system. However, I really do hope games start moving to 64bit executables soon as the 4GB limit for 32bit applications on x64 systems is pretty low.
