File write speed seems lower than it should be

Hi all.

I am currently, using Dxtory, trying to record WoW at a lossless 1920x1080 at 60fps. I have tried a number of codecs, including Dxtory's own, Lagarith and Utvideo.

Although my ingame FPS is constantly above 60fps ,I am simply unable to reach a consistent file write speed of 60fps. It seems to hang around 40-50 fps.

Is this expected with my following setup? If not, what might I do to alleviate this?


Operating System
Windows 7 Home Premium 64-bit SP1

CPU
Intel Core i5 2500 @ 3.30GHz
Sandy Bridge 32nm Technology

RAM
8.00GB Dual-Channel DDR3 @ 668MHz (9-9-9-24)

Motherboard
ASUSTeK Computer INC. P8Z68-V LX (LGA1155)

Graphics
S240HL (1920x1080@60Hz)
2047MB NVIDIA GeForce GTX 660 Ti (ASUStek Computer Inc)

232GB Samsung SSD 850 EVO 250GB ATA Device (SSD) (WRITE SPEED: 478 MB/SEC)
931GB Seagate ST31000528AS ATA Device (SATA) 31 °C (WRITE SPEED: 88 MB/SEC)


As a note, I am writing to the (more or less empty) SSD and WoW is installed on my C.

Many thanks!

Thanks for the reply, kapitalistas.

You are right that lowering the settings would help, but I do not want to sacrifice quality without needing to, and, it seems to me that I shouldn't have to with the drives I have.

Further to my OP; it would seem it's not my CPU that is bottlenecking my file write speed: I'm not sure if this is a valuable measure of CPU bottlenecking, but Windows Task Manager indicates that my CPU Usage never goes above 55-60% during recording.
