Q: Anyone facing lag on OS X Mavericks ?

Man........... THANK YOU!!!

I simply opened and closed my Autocad 2012 and now it's perfect..

Thanks again....

SINCE 2008 IVE BEEN USING APPLE PRODUCTS .. HONESTLY SPEAKING THIS IS THE FIRST TIME EVER IM ACTUALLY REPLYING TO A THREAD ON APPLE SUPPORT COMMUNITIES .. PEDRO MY BRO - YOU ARE A GENIUS .. YOU SAVED MY LIFE .. YOU JUST DID .. .. THANK YOUUUU SOOOOOOOO MUCH MY FRIEND

Autocad 2013 may be the reason my Mac Pro is now lagging suddenly.  It was corrupted and I had to uninstall it last night, and since that reboot the mac has been horribly glitchy even with nothing else running.  I will try to reinstall 2013 tonight after work.  Hopefully this will fix it.  Problem started last night around 9pm when mac force closed it during a restart. 

I installed autocad 2013 and as soon as it finished booting all of the graphical glitches are fixed.  Didn't even need to restart.  I sincerely hope apple and auto desk look into this issue.

Just chipping in regarding this weird issue on my new mbp 15 with gt750m and 512gb ssd + mavericks 10.9.4. Earlier today I've spend more than an hour on the phone with the Apple Care person just to fix this random issue that occurred out of nowhere. After doing everything they told me to do including doing a system restore, and still cannot fix the problem, I just had to do my own research as the last option before sending it back to the Apple store for repair. Luckily I found this thread and followed the popular consensus solution for the problem by installing Autocad 2014 and opening it once. And what do you know, the screen tearing/lagging problem disappeared just like that.

I dunno what is the cause of the problem when at first I thought it was the gpu hardware problem. But weirdly enough, installing and opening the Autocad even just once seem to do the trick.

I will be calling the Apple Care again tomorrow and let them know this issue because this needs to be fixed asap before the upcoming Yosemite.

I had the same problem since last evening, it surprisingly solved by running AutoCAD 2013.

I think, Autocad was the reason for creating this problem in the first place, and somehow it resolves it by running it again.

Give it a try

Same problem. And I found a lot of users with same problem on google.

The exact same thing happened to me on my Macbook Air! Maya and the next day everything was flickering

In my case, the monitor had switched from 1080p to 1080i (interlace).  Switching back to 1080p (progressive) fixed the graphical tearing issues.
