Strange (possibly normal?) Lantern Issue

[TheBlindHouse]

First I'd like to say that I'm sorry if this has been posted before, I couldn't find an answer anywhere. I just got this game via Steam about an hour or 2 ago.

Basically, when I press the "f" key to take out or put away the lantern, Daniel's hand and the lantern sort of...stutter, I suppose. I wish I had a better way to explain it, but that's basically what it is. As he's pulling out or putting away the lantern, the animation sort of hitches as if the frame rate were dropping, but as far as I can tell, it's not. Just the animation itself gives this effect. I do have some overclocked components, so I'll try putting those at stock speeds to see if that fixes anything, but I'm open to any other suggestions.


Here's my system specs:

CPU: AMD Phenom ii x4 965 BE (OC'd to 3.8Ghz)
RAM: 4 Gigs of DDR3 @1333Mhz
GPU: AMD Radeon HD 7850 XFX Double D (OC'd core clock to 1050Mhz)
Motherboard: GA-990FXA-UD3 Rev 1.1
OS: Windows 7 Home Premium 64-bit

Just added hpl.log

Lowering details does not help.
