4G Just means it's the 4th Generation of Razer's mice. Thus using a 4th generation sensor.

Not really, everyone can agree a smooth travel and accurate tracking are what you want.

Only DPI/Speed are subjective.

And guess what?

It's still a Philips Twin Eye!

smooth travel and accuracy seem like basic functions of any mouse. performance is based on how the mouse works in certain, in this case, gaming applications, and given that most modern mice use mostly the same parts superiority is going to come down to the end users opinion. I guess im saying that its just hard to quantify mouse performance

Perhaps a thread combination and multiple sources cited.

Andddd I hope they make a DA like this.

There are several basic things that do:

1) There should be no positive/negative acceleration due to sensor/calculation inaccuracies. It should only happen if enabled in software by the user.

2) It should be able to track perfectly as fast as the user can move his/her hand (after a certain speed tracking becomes erratic, with any mouse).

3) It should not jitter.

4) It should have as low of a liftoff distance as possible.

Sure, whether you think a mouse is comfortable or has enough buttons or whatever is all subjective. IMO comfort is the most important thing anyway. Just don't forget about the performance that is measurable, because no matter who you are they do make a difference.

I agree. When I look for a mouse, I make sure it meets every single one of these criteria. Since I am a low speed player, I also look for a high cutoff distance with speed in order to ensure it doesn't crap out at high speeds.

Everyone can talk crap about razer, but their 1800DPI Deathadder is one of the best mice ever made. It meets every one of those requirements and then some.

However, I don't see everyone's problems with liftoff distance. I'm a low sens player so I'm applicable to complaints, but I've had no problem with the ~2mm liftoff distance of the deathadder 1800.

And then some would include the bottom of the mouse digging into surfaces because of the defective shell design mixed with their super thin recessed teflon feet. And I have used the 3G deathadder and two of the 3.5G deathadders, all of them had a higher lift off distance than 2mm on all of my cloth pads.

Sensor performance wise yes, the 3G DA was awesome.

If you have two sensors looking at the same thing but from different angles, they might see different things because of light/laser sources, improving accuracy. It also allows for depth perception, by calculating how far apart the images from the sensors are from each other (if not flat against a surface, it will be like it's seeing 'crosseyed'). That allows for a 0mm liftoff distance if you want it, and for improved tracking on uneven surfaces (like a worn out desk top) because it will be able to calculate the speed of the moving surface vs how far away it is from the mouse.

Of course, this is Razer we're talking about, and two different sensors (and therefore always two different images) so I doubt they actually did these things. Most likely they just compare the two images and average the speed between them.
There are a few problems.

First of all (unlike GEIL) the used laser sensor is almost certainly a Philips twin-eye. That sensor works differently, it doesn't take images.

Also, current sensors don't actually compare the whole images, only pixels, so it doesn't really work with 2 pictures from different angles.

For a mouse manufacturer there are a few other problems.
The sensors make images at a microscopic level an work best at a certain distance. Because the sensors are too big you would have problems to get an image of the same area without putting the sensors out of their comfort zone (distance, too extreme angle).

Sensors are also designed to send movement data (delta x/y) to the MCU of the mouse, not images. You can read the current frame of the sensor but it would most likely not work a couple of thousand times per second.

As a sensor manufacturer like Avago you could theoretically make such a sensor but you would most likely end up with a way too expensive sensor.

Same thing most likely.
.. but with different sensors.
