Everything Apple (the Mac heads thread)

Are you using the OSX drivers or the Nvidia web drivers? If the former, try the latter.

Edit: I don't think the 1080ti is natively supported so you must be using the web drivers.

The web drivers don't actually support the 1080 so apparently performance is very buggy:

You'll probably just have to wait for Nvidia to improve the driver.

Have a MacPro at work with a 1080ti inside. Performance measured with Cinebench is below a 2014 iMac. Not so happy about this - any ideas?
