How can I download Nvidia's drivers for OS X, or when will 10.8.3 be out and will the graphics be better? This computers graphics SUCK at youtube and it's really irritating. :/
The drivers are usually updated with a new OS X version. Nvidia does not provide extra drivers for the rMBP.
Anyway, what kind of problems do you have with youtube? I never experienced any.
if I fullscreen the youtube video the audio becomes VERY out of sync (a few seconds ahead) and the performance is generally very crappy.
Do you have latest version of Flash installed? Also, try the HTML5 player.
Well, do you have the same problem with a different browser and a standalone Flash installation? What about Chrome Beta?
Chrome includes Flash built in, and I have auto-update enabled.
