Everything rendering low-quality all of a sudden.

All my skyboxes, textures, and models are all low quality. I don’t know why but I can’t seem to fix it. All the textures and skyboxes are the defaults so it’s not an import issue. Also, I light-mapped the scene but I don’t think that effected anything quality-wise. here are some screenshots:

Please help. This wasn’t like this yesterday. P.S. I’m using a Mac and this is Unity 4.1.2f1

You switched your build target to one of the mobile devices. Set it back to the desktop and it should be fine.

File->Build-Settings, then click on a desktop platform, and “switch platform”
