Sometimes everything (mobs, people, myself (ohgod)) will just disappear if they go off my screen and they won't reload.

>mfw I'm punching an invisible mob that aggroed me while I was in one of my blind stupors :(
Like cereally, I can see things on my radar, but their models just won't load.
I've found 2 ways of fixing it: 1 is if I run a significant distance my character model will "blink" per se and everything will act normal and I can see things again.
The other is I simply relog.
My question to you all is does/has anyone else have/had this problem, or does anyone have any suggestions?
I checked my graphics drivers and they seem to be completely updated. I really would not be a happy panda if I needed to go about doing a full re-installation, seeing as how like, yeah, took like a billion hours the first time around.
Anyone who supplies me with any advice/answers will receive a complimentary gallon of PCP:

Thanks in advance
