Low settings, 3 times lower than native resolution and you call it playable?
A year ago I would of been delighted to play Skyrim on low at 800 x 600. :P
At that point I still had my old laptop and could barely play Oblivion on low at 800 x 600. I can't believe I used to be fine with that. I played Oblivion for over 100 hours on that machine.
