After playing on my MacBook Pro with Boot Camp for the past couple years, I found that if you lower the resolution to something custom like 745 x 425, disable those horrible ht texture packs that available for free Download, then use the mod to force fullscreen while you have "windowed mode" checked the game works flawlessly with 60fps inside, and 25-40fps outside, at least that's what I found I'm also using an Intel HD 3000 integrated video card... When I get home, I will look up the exact mod that I'm using to force the full-screen mode while I'm windowed mode... I can also copy and paste my Skyrim INI files if you would like.
