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:
[ eMachines Official Site - - T5230 Product Details ] Is the base I have
Added:
Nvidia 8500 video card
2gb of ram (total of 2 gb in the system)

Hello and welcome spastic

My apologies for the delay. Might you please download and install Process Explorer to provide more detail about what exactly is going on in your system when it's busy. A screen shot of that detail would be appreciated.
