It all depends on how much detail you want to see.
320x200, you didn't need 1080p to spot the enemies in this, no snipers though
640x400 further shrunk for performance
640x480 full screen
800x600 sniping possible
1024x768 gotto be able to spot the enemies in the foliage
Since then games have been cranking up the detail but kept 720p as the target resolution (on consoles anyway)
It's about time all that detail is revealed in 1080p (or 4K for the pc crowd)
