Crashing/lagging/unstable

Been troubleshooting all day now to no avail, including complete erasing and redownload RB 6.5.3 Every time I go to open RB i have to go to rekordbox3.settings and change the disable open gl value from 0 to 1. That allows RB to finally open and not "unexpectedly quit". Once opened the audio waveforms are gltchy/blurry/weird looking. They do not move smoothly and beat grids do not line up. Basically unusable.  Ran the Activity Monitor and it was reading 112% cpu usage playing only 1 track. I did not have any of these problems running RB 6.5.3 all September!!! Please I need some fix here. Im djing with Atrak this friday Oct 15!!!!!
