In the beginning, SoW will be just like IL2 was on initial release. No one will be able to play it on maximum graphic settings. Then slowly, over time the hardware will catch up, just like it did with the various upgrades of IL2.
And we all remember how ground breaking IL2 looked back then, even on our 1.3 gig Pentiums with 512 of ram and a GF4 Ti 4400.
