Need help adjusting latency. THANKS!!!

I have 8 gigs of Ram on my macbook pro 2.26 processor, 10.9.5 operating system. Running Cubase 8
Audio interface is UR 12. Im experiencing lots of latency just using minimal reverb, compressor, and sound plug ins.

Please confirm if these settings are accurate as Im not sure

Activate Multi Processing -checked
Activate Asio Guard -checked Disk Preload - 4 sec
Adjust Record Latency - checked
Asia Guard Level - Normal

Buffer is set to 512.

Out of curiosity… are you using a convolution reverb? These are notorious for adding latency.

Not sure about the rest of your post as I use Windows.
