WoW lag when moving Master toon

So, when I first started using ISboxer, everything ran smoothly. No lag, no stutter, no skipping, etc. After a while of playing and learning how best to configure my key bindings, I decided to go to bed for the night, thus turning off the computer. The next morning, I turned the computer back on, turned on ISboxer, and started running my 3 toons again. Only, this time, I experienced a large amount of stuttering whenever I moved the master toon. If I switched windows, thus switching master toons, same problem. It mostly happens when I turn in circles, and less likely to happen when just moving straight. I played with the CPU settings (Round robin, no dedicated CPUs, etc) to no avail. I turned off foreground framerate for all slots with no avail either. What should I do next?

PC specs:
Intel Core I7-3770
Gigabyte GA-Z77x-UD5H
Sapphire Radeon 7870 Ghz Edition

Provide a diagnostic.

I'm assuming this is a freezing issue, but I'm not completely freezing. I simply just stutter. Plus, when I attempt to make one after running around a bit and stuttering, it says the attempt failed anyway. I am multiboxing 3 toons, so I tried all 3 instances with no luck. However, the crash report is: http://privatepaste.com/cd2bc68fce <-- of me opening the game through launcher by the way.

First try shutting down:

Code:

70. raptr - Process ID: 7792 (C:\PROGRA~2\Raptr\raptr.exe)
71. raptr_encoder_server64 - Process ID: 9736
72. raptr_ep64 - Process ID: 4280
73. raptr_im - Process ID: 9060 (C:\PROGRA~2\Raptr\raptr_im.exe)

If that doesn't work then continue shutting down all background programs which don't require you to multibox, and if that doesn't work, then try completely uninstalling AVG, restarting your computer, and trying again.

Ending those processes worked. Why would those processes have affected my game so much? Its part of the AMD update process, so I thought it would try to IMPROVE gameplay, not restrict it.

While it seems that AMD and Raptr have some sort of contract/deal, its main focus is:

Raptr is a social networking website and instant messenger, targeted towards video game players.

It's likely incompatible with Inner Space because of its intrusive behavior when attempting to track your gameplay and provide an in-game overlay.

Ah, I see. The Raptr app that I have attempts at optimizing certain games for higher performance, but it does seem to focus mainly on IM stuff. Thank you for all your help, though.
