G9 laser imprecision

Greetings,

I'd like to know who should I contact in case the G9 mouse I've just bought isn't working as intended (read:the laser device not working well).

 

In order to be precise, whenever I make a fast movement of -let's say-  35 cms, the pointer in reality does 5-15 cms on the screen depending on either higher and lower  speed.

I tried to increase the DPI till the max (3200) and then to lower the sensibility via SetPoint to have roughly the same precision , but even if at 3200 DPI the cursor is way faster the problem still occurs.

 

To summarize, I can not make any fast movement at all.

 

I tried it both in-game (Enemy Territory-Quake Wars) and then on the desktop, but the pointer will instant-slow down anyway.

 

Thanks in advance

Hi a1b2,

 

maybe it's defective or maybe this is because it's a laser mouse. Laser mice are still weak in tracking fast movements. The G9 is no competition for the MX518(for example) when it comes to tracking fast movements. Too bad it's not written on the package or on the Logitech website.

 

What kind of mousepad are you using?

Re: G9 laser imprecision

I'm currently using a Razer Destructor which is supposed to give 37% more accuracy combined with laser mouses,and has been specifically studied for better performance with those (heh).

I even tried using no pad at all, it works better but the problem still occurs,even if in a far less noticeable way.

Using a white sheet of normal printer paper however there's no problem at all.

Since using such a kind of mousepad for gaming would definitely not be the brightest idea,I'd like to hear any advice.

 

According to the Manual the mice was provided with: "Your G9 delivers the most advanced technology for superior tracking precision and speed. [...] . The gaming-grade 3200 DPI Laser Engine gives you pixel-precise tracking at any speed".

 

This means that either the informations Logitech gives to  their customers regarding their products are blatantly untrue, or that the mouse I bought is unfortunately broken; I guess that in both cases I should have the right to ask for a refund,or at least a change.

 

Thanks in advance

Well, it better be defective, because if a gaming mouse is working best on a white sheet of paper, then I don't understand what the "gaming" stands for. I've never seen a pro-gamer playing on a sheet of paper on a tournament for example.

 

Anyway, some time ago I found out something very interesting. I was reading the specifications of the MX518, G5 and G9 and especially the maximum speed specs. According to the official Logitech website the max speed for the MX518 is supposed to be 1m/s while for the G5 and G9 it's said to be 1.1 - 1.6m/s. This is simply not true. I've used all three models and trying on a few different surfaces I was unable to make the MX518 skip or lag while the G5 and G9 skipped on the same surfaces(I was using the same settings for each mouse). Those specs on the website are definitely wrong, no doubt about it. We can hope someone from Logitech will clarify those things.

 

If you have a friend who also owns a G9 maybe you can try it out and see if his/hers one has the same problem.

Re: G9 laser imprecision

Though these replies don't help my morale, I'm still grateful for all of them.

Is there any Logitech employer who could at least give me feedback on this?

Hi:smileyhappy:,

 

The best way to check this is to compare your G9 with another G9. Testing it on a different computer (on similar surfaces) will also help to check if it is a hardware defect (which seems possible, based onyour description).

Re: G9 laser imprecision

Thanks for your feedback.

However, you may agree that buying (as I don't have any stores in my area who let customers try the mices before buyin them) another G9 with the sole purpose of checking if it's working as intended or not isn't simply an option.

I've been trying it on a laptop (HP pavilion dv 6000), which I guess may cause problems. I'll check it as soon as possible on my normal,faster,PC.

You can't really blame Logitech for that becuase that are the specs provided by the sensor manufacturer (Avago Technologies) which are based on White Paper, Photo Paper, White Formica, Black Formice and Spruce/White Pine for theG5 and G9. The specs of the MX518 are afaik based on White Paper, Manila, Burl, Black Walnut and Black Copy.

 

So specs don't say much about gaming performance.

 

The specs oft the G9x ("up to 150 ips on most popular gaming-mousepad surfaces") also don't guarantee you very good performance on your specific mousepad, although I believe the G9x will perform very well. :smileywink:

Re: G9 laser imprecision

So if the specs of a gaming mouse don't say much about it's gaming performance isn't that wrong? Isn't it wrong to post specs for a gaming mouse which has been tested on non gaming surfaces? Plus the specs provided by Avago Technologies are not exactly the same as those on the Logitech website.

 

I don't blame anybody, I just see discrepancies in all these specs. I'm not competent enough to know everything about the subject so it would be nice if someone explains all these discrepancies. And obviously I'm not the only one who needs clarifications.

 

As for the little tests I made with the MX518, G5 and G9. The surfaces I tried were SteelSeries QcK, Icemat Black, my wooden desk, white A4 sheet of paper and an old Everglide Attack Optical Smoke mousepad. The laser mice performed best on the Everglide mousepad and on the white paper but I was still able to make them skip and lag without much effort.

Hi:smileyhappy:,

 

Is there a signnificant difference in the G9 performance on different surfaces?
