Does anyone know what the level cap is for skyrim? And when you stop obtaining perk points? I heard that level 50 was the last time you received a perk point but i just leveled to 52 and im still getting perk points...

If you level all skills to 100, you can reach level 81. You keep getting perk points all the way through.

Edit: Enemies stop leveling with you after 50, though. That means no tougher dragons, no higher level bandits/draugr/what-have-you. For all intents and purposes, once you hit 50, there's nothing new to see.
