One thing gamers seek above all else is an edge; an advantage that gives them the ability to take that 1st place position with ease; the sleek design, light weight and almost instant response time of the Razer Lachesis does just that. The revolutionary 4000DPI (Dots Per Inch) of the Lachesis, 800DPI higher than the competition, will get the crosshairs of your gun on your enemy before he can blink. Combine this with the pulsating light of the Razer emblem on the back of the mouse, the glowing mouse wheel and the gold plated USB head, the Razer Lachesis is literally “drop dead gorgeous.” For the high sensitivity gamers out there this mouse is an answer to your ever higher demands.
However given the Lachesis’s small size, the lower sensitivity player may have a difficult time getting a good grip when they need to reposition the mouse on the mouse pad. If you perspire, like me, the mouse can become somewhat of a “wet fish” and occasionally go flying across the room. Experiencing this exact situation gave me the opportunity to test the durability of the mouse. After 3 or 4 times of the mouse hitting the floor, combined with the occasional aggravated smash on the table, I found this mouse to be surprisingly tough for its small size. I did not notice a single difference in usability.
The 3G laser in this mouse addresses one of the key issues with lifting a mouse. The optical LED based sensors of the last generation of gaming mice could still move the cursor at 2-3cm above the pad. The 3G laser has it down to about 3mm, limiting the recoil when you pick up and put down the mouse.
The body of the Lachesis has 3 Zero-acoustic Ultraslick Teflon feet that allow for the use of very little force to get the mouse moving, decreasing the chance of over or under shooting the target. Nine independently programmable buttons line the outside of the mouse. There is also a profile button on the bottom of the mouse. The primary mouse buttons are very sensitive to pressure much like a hair trigger, which can be a good thing or a bad thing depending upon your style of play. There are 2 LED’s one placed at the mouse wheel and the other under the Razer Emblem at the back of the mouse. The one under the emblem pulsates on and off approximately every 5 seconds. You can choose to turn the pulsating off in the configuration panel if that is a distraction.
The Razer Lachesis also has a fully customizable configuration panel with a 32KB onboard memory.
Some specific points of interest are the Polling rate, Dpi Switcher, the Advanced Function Input tab and the Profile Options tab.
Every second counts in high-paced game play. The Lachesis’s Polling rate (how many reference messages are sent from the mouse to the computer per second) is maxed at 1000Hz = 1000 messages per second. This is equivalent to a reaction time of one millisecond. Setting the Polling rate at less Hz equals slower reaction time from the mouse. If you’re on a laptop not plugged into an outlet, this feature can be beneficial in conserving battery life by turning down the Hz.
The Dpi Switcher allows you to set 5 keys to different sensitivities between the range of 125 and 4000 with incremental settings you can switch to or from with the DPI settings selection shown below.
The Advanced Function Input tab is accessed by clicking the advanced functions selection located directly above the DPI Settings selection. This tab allows you to set the selected button to do any number of things including those listed on the menus below. However, using the macros feature is difficult and not always reliable. When trying to assign macros, you highlight the macros feature and any button on the keyboard you push after that will then be activated inside the box, (which includes releasing pressed keys). If you hold keys down, they’ll repetitively duplicate—not allowing you to assign it to single button activation/deactivation. The single button feature which is to the left of the macro feature, works perfectly. It is easily set up to throw grenades, cast spells, change weapons in any number of assorted ways to increase your gaming experience for all fast-paced FPS’s (First Person Shooter) and RPG’s (Role Playing Games).
The configuration panel of the Lachesis allows for 5 fully customizable profiles. The Lachesis lets you independently program each of the 9 buttons differently for each game. The Profile Options Tab allows you to set a profile to be activated when a game executable starts, giving you the ability to instantly change to your optimum settings for any game. You can also manually control the profile settings in case you want to set them up for multiple vehicles or weapons in one specific game. The Master Guide that comes with the mouse goes into more detail about all of the setting capabilities. Coming in three colors; Wraith red, Phantom white, and Banshee blue there is a Razer Lachesis to fit almost any PC system.
I have found one of the biggest advantages that the Razer Lachesis gives in games such as Battlefield 2 (BF2) and Crysis is that you can program the individual buttons and profiles to meet any of your in game situation needs. Games such as BF2 and Crysis have many different vehicles and abilities, that far exceed the number of buttons on any mouse. This usually requires you to sacrifice one of the fingers you are using for movement, (usually on the W, A, S, D keys), making it more difficult to juke (dodge) oncoming vehicles and bullets. As an example, to solve this challenge with the Lachesis, in BF2 I programmed profile 1 on the 4 and 5 buttons using the advanced function selection single key option shown below, to “E” (enter vehicle) and “Z” (prone/lay down) allowing me to juke and bunny hop (jump then lay down repeatedly) through the enemy lines and steal their tank(s).
The tanks in BF2 have a slower turret spin speed than your character making it seem like you just lost half your DPI. When I got in the tank, I changed to profile 2, (as shown below), setting the DPI from what was 1750 to 3500 changing the “Z” (prone/lay down) setting, which doesn’t do anything while in a tank, to “X” (deploy smoke grenade).
Using the Lachesis in this way gave me a clear advantage. I earned 120+ points when the average was 60-70 points a game. The Lachesis can be programmed similarly for Crysis. However, Crysis has 5 additional commands for bonus strength, speed, armor, invisibility, and weapon add-ons. These are normally set to keyboard keys and are selectable through holding down the universal scrolling button. I like to set these to the Lachesis buttons 3, 4, 5, 8, and 9 decreasing the time it takes to use them while allowing me to juke.
The effectiveness of the easily pressed primary buttons, Teflon feet, light weight, 1ms reaction time and high sensitivity became apparent in games such as CSS (Counter Strike Source) and COD4 (Call of Duty 4) is another benefit of the Razer Lachesis. In these games the last man standing is usually the first man to shoot. Because you have a high probability of dying from only one bullet,(compared to BF2 and Crysis which takes an average of 7 bullets to kill), the ability to get your crosshairs on your enemy and let the bullets fly is paramount. In these games the proof is in the results. I averaged a 3.00 KDR (3/1 kill per death ratio) where the pros normally get a 2.50 KDR.
