Amnesia--Severe Fraps lag

[freeloaderfreddy]

Hello all, I just recently downloaded the demo for Amnesia: The Dark Descent, and it runs very smooth on high specs, getting 60 or more frames per second. I decided to record gameplay of the demo with Fraps to see my reactions after I've finished the demo, and if that went well, I'd buy the full version of the game and do a "Let's Play" type of thing. However, when I start recording, the frames drop from 60 all the way down to 10, which is basically unplayable. I've tried putting the resolution and other graphics options to the lowest possible settings and still no luck, it still runs at 10 frames while recording. There are no background programs running, just Fraps and Amnesia is all. I even tried using an external hard drive, having Fraps run from and record to the external one while Amnesia ran from the main C Drive, and that didn't help at all either. I haven't found any other threads where somebody is experiencing the same problem as me, so I'm at a loss...

My PC Specs are as follows:
- NVIDIA GeForce GTX 560 Ti GPU
- AMD FX-4100 3.60 GHz Quad-core Processor
- 8 GB DDR3 RAM
- Windows 7 64-bit OS

Anyway, I have no clue what to do, so any input would be very much appreciated!
