enghel ewwow :D

just kidding,
very informative video!

check this video too

I would love to work in such a place!!

If I get rich I will definitely start my own mouse company and I will make the best gaming mouse ever :-)

90g WMO with an amazing sensor and low latency all round.

Also a light version at around 65g.

THEN THE OPTICAL FREEHANDED DEVICE.

Logitech distinguishes itself from other mouse manufacturers (roccat, steelseries and especially razer) by not hopping on the DPI train. I respect how honest this guy is about interpolated resolutions on modern day mice, also seems to know his stuff about sensors.

"Logitech distinguishes itself from other mouse manufacturers (roccat, steelseries and especially razer) by not hopping on the DPI train"

Yeh they do...

I know they have max. 4000 interpolated dpi on the g400 (sensor default steps), but afaik they have no models with excessively high dpi values like the razer mice have. G100s is being advertised with max. 2500 dpi which i think is a bold move considering all newer mice have 5000+ dpi.

g500/g600/g700...

Well they are laser models they have higher dpi, i was talking about opticals :p

so they are on the DPI train.

Yeah i guess so, laser wise... but in the optical segment there's a huge gap between for example the logitech g100s (2500 dpi) and razer da 2013 (6400 dpi) was just trying to point that out.

among opticals only razer got higher dpi cause they got somewhat exclusive sensor

So infact it isn't really logitech not hopping on the DPI train, it's more about razer being one step ahead in the dpi marketing :D

also g400/g400s 4000dpi are native

noe, 800/3600 are native increments steps

http://www.avagotech.com/docs/AV02-3346EN

I'm reading everywhere (including in that OCN thread about mouse sensors) that the g400(s) uses a variant of the 3090 sensor called the S3095 which utilizes 800 and 3600 dpi as native resolutions, all others are interpolated... where is that Skylit dude maybe he can shed some light on this

whatever, noone is using that much anyway

G400 800/3600
G400S 800/4000

They differ by SROM enhancement.

The above video doesn't change anything in terms of Logitech product placement and competing in the high DPI market.

This is simply a campaign to help users understand technicalities such as DPI.

The engeneer in the video clip said there is only one real "native" dpi step, but then they divid it. How can you have 2 native dpi steps?

The numbers I referred to are native registries to the sensor(s) SROM code.

The senior engineer in the video is talking about the native pixel by pixel imaging matrix. Also referred to as an Array.

Ex:
http://cdn.overclock.net/0/08/08738628_pixelmatrix_ph.jpeg

The above matrix size is 30*30 or a coverage area of 900.

To increase CPI capability, the matrix is divided and multiplied emulating a higher ceiling, but as mentioned, this opens up the doors for negative side effects as you cut each pixel over and over again.

In this video, a logi representative explains that higher DPI doesn't mean better tracking or a better product overall, it's almost as if higher DPI can cause more issues rather than benefits.

Razer representatives on the other hand keep promoting the DPI as groundbreaking and crucial for your gaming needs.

I think this is what padawan was trying to say

More or less, razer puts alot more emphasis on the dpi indeed.

p.s. have a plus, even though it looks like you aren't in need of them

I don't need them so I'm kindly giving it back

I am cheap. :(

inb4 RAZER ULTRAOBLIVIONIZER WITH 64000 DPI

so how is g100s shapewise? is it similar to mx300 and pilot or has some another feel?

absolute copy of mx300/g1/g100
the only thing i don't like is fairly low max speed and 1000dpi/500hz without drivers

meh 1000dpi is not good. but the price is!

what isn't good about 1000dpi?

noctis switched to it as well..

pretty cool, but not really that much into it, would love some deeper stuff about how DSP algorithms work including framerate operations, afaik they're the only company who actually got access to avago DSP documentation and able to make their own sroms and stuff. Though it seems razer also got it lately.

bookmark this and throw it at anyone claiming dpi matters :>

well it does

it's just sometimes less is more ;]

I've always been confused by my g400. Since 800 is a "native" DPI setting, why does 400 dpi feel so much better for so many people? Most people I know, including myself, use 400 dpi @ 500hz. I've only had 1 person tell me they use 3600 dpi because it makes the tracking feel better.

To me, 400 dpi feels much more responsive and accurate. 800 dpi and over feel "floaty." Tested on Linux and Windows XP.

People make up subjective shit. There is probably no difference. Of course, different dpis can still feel different because of the movement speed and how everything works together, but actual response time and sensitivity? Nahhhhh.

Is the g100s better than the g1 if you don't mind mouse prediction? much cheaper.

@byce

dpi depends on screen resolution.
low reso for low dpi, high reso for high dpi

Thanks, makes sense. I use a low resolution on a CRT.

I'm glad that he said angle snapping is a "nightmare" for gamers.

Logitech was originally madly in love with angle snapping (prediction).

Well I don't think anyone was really aware of mouse prediction at the time, and as far as i understand, I don't think there is a mouse with no angle snapping at all, just different levels of angle snapping.
Personally, I actually prefer higher levels of angle snapping. I was using an abyssus for about a year or two and recently decided to screw the abyssus shell top onto my old salmosa and I must say I prefer it much more. I know that noctis/winz/av3k/etc have also used or are still using a salmosa/abyssus mod, so I guess I'm not the only player to prefer higher mouse prediction.
From my experience playing quake with many different mice, sensors with higher levels of angle snapping are better for hit-scan trace weapons, such as LG, but are overall worse for rail. I think it's no coincidence that some of the best LG aimers (strenx,evil) use the SS kinzu which probably features the highest level of angle snapping among gaming mice; I've noticed that many other lg-heavy players often use m_filter or low values of cg_filter_angles which act similar to angle snapping.
Ideally, gaming mice should allow you to enable/disable mouse different values of prediction via firmware.

There's an inherit algorithm in certain sensors rooting from the Agilent 2020 architecture, but an angle snapping "effect" can be caused by certain coding additions or even errors on mice that share the same sensor specifics.

But is there such as a thing as a mouse with no angle snapping at all?
Btw, I need a new mouse and I'm debating whether to get the Logitech G1 or the Logitech g100s. I have recently bought a roccat lua, which uses the same sensor (avago A3050) as the g100s if I'm not mistaken, and the tracking felt great. Unfortunately, the mouse was just a bit too small and way too narrow, especially at front.

Now i'm really not sure whether to buy a logitech g1 or a g100s, can you maybe help out with this decision?

G1 cause hal_9000 uses/used it :D
