Hello, I have a Razer Lachesis, and am currently having a problem which I can't resolve. First off I have driver version installed 1.10, and firmware version 1.91.

The problem i am having is when in a game (which can use a lot of resources) (Aion & World of Warcraft WOTLK) anything that causes a load on the system, the mouse getting really erratic. It will get really slow moving and then just freak out going all over the place. Sometime I will right-click (press and hold) and my characters will just start spinning in circles.

I haven't been able to pin-point the exact thing causing it, but it only happens while a game is up (not while internet browser or anything such as that is open). It is almost to the point where it makes the game un-playable.

The exact settings though Razer software I am using is
Polling Rate: 500hz
DPI: 4000
Sensitivity: 2.5
Acceleration: (on) 8
Win Pointer Speed: 4.5
X Axis: 10
Y Axis: 10
Universal Scroll: Yes
On-The-Fly (Show of Screen): Yes
Double Click Speed: about half
Auto Switching Override: Yes
Enable OSD: No
System Tray Default: Yes
Logos On.

I am really at a loss for words with this. I have Google'd this numerous of times hoping someone would find the answer to it, but so far no luck.

For my system specs:
