Was running a random heroic and had my FPS drop to 0 in combat im using Demonic and Enyo. Not sure what the cause ended up having to alt F4 out of wow as it became none responsive.
seems to have the same problem with Singular spent some time on the training dummies to see if that would trigger the freeze but seems to be only when i go into an instance with a grp (sorry for the log arse log)
2 more logs same issue both with enyo using the lock and a monk, also attempting to use questing had a insta dc but sofar on the 2nd attempt there are no issues
Usually, FPS problems are caused by plugins or botbases that use bad techniques. However, we see no offending plugins in your log, and Enyo and LazyRaider are solid botbases.
At the moment, this looks suspiciously like a video driver problem. But, to cover all the bases, please see if this article can help you isolate the problem:
tried updating driver, swapped from DirectX versions removed all addons, gonna run a virus check and try again as that seems to be the last option i have using the info in your link
