In the outside areas tougher things spawn as you increase in level yes, also they move (much/ridculously/stupidly) faster, and appear to be more accurate and do more damage with weapons.
Lvl 16 now and as my Perception is only 6 if I run around too much I can be reduced to about a 1/2 health by mere raiders before they even show up as red lines on the compass and I even know where they are. That is with toughness and cyborg perks and wearing ranger combat armour.
If I play through again in 6 months time when some decent mods have appeared I think I'll be going hvy stealth and assoc. perks and melee/h2h
