I recently was shipped a G500 mouse after having problems with a previous G3, after time it seems the mouse stops functioning properly. The dpi becomes very random, and the speed and accuracy of the mouse starts changing on it's own. This usually happens every restart or upon idling the cpu and coming back. I have not been able to find a fix for this anywhere and I do not know if it's the mouse or CPU related. I have had this problem before thinking it was the cpu but now I have built a brand new cpu and I am clueless. I would really like to find a solution to this problem. I am currently using Windows 7, and have the drivers installed. I tried uninstalling/reinstalling drivers several times.
Basically let me explain it a little better. My mouse is currently set at 2000 dpi and max sens at 1000 Hz polling rate. The mouse does not move like 2000 DPI at max sense @ 1000 Hz polling rate. The mouse initially worked fine, there was nothing wrong but nothing has changed on my cpu either. Any idea what the problem is? This is really a headache.

I've done what you've said. Clearly there is a difference between using OS pointer speed/accel and the drivers. With the drivers I've noticed the mouse is faster, however It's still not at it's actual DPI. Now I had the G3 previously and had the same problem. If it's polite to ask, how technical are the mods here? I mean are you simply trained in basic principles regarding tech support or would you know enough about the mice, and CPUs in general to help me find the cause of the problem?
I recently tried reinstalling windows XP instead of using Windows 7 and the mouse was running fine upon installation. I left the computer on IDLE and came back this morning to find that It switched to the higher DPI on it's own, and not only that but It was also SLOWER at the lower DPI then when orginally installed in a fresh installation. I seriously don't understand the problem, is there a possible conflict with the computer and mice due to the power usage when idling a cpu?
Are there any diagnostic tools out there that could possibly pin point the problem or maybe analyze my DPI? Clearly if we know the mouse is supposedly running at the correct DPI etc. that the problem is not with the mouse but rather something in the CPU.
Now both the G5 and G3 are DPI changing mice, is it theoritically possible the mouse is malfunctioning internally, or how likely is that? I don't think it would make sense that I'd have two mice from logitech which are both bad, and because the mouse initially worked that also baffles me.
What about device conflict, registry conflicts, or anything else? If there was a diagnostics tool of some sort that would probably help a lot because we could rule out many possibilities. I suppose there isn't though. Any recommendations?
If I can't find a fix for this then I'm afraid I'm done with logitech. Regardless of bad luck with two bad mice or not this is too much stress and hassle for a hardcore gamer like myself to deal with. I hope this is something simple and something on my part. The complexity and uniqueness of the problem makes me fear otherwise.

Well, FYI, I am fairly technical, which is why this issue is confusing me. If you did what I instructed above, then you have set the Logitech driver to issue a 1:1 DPI command from the mouse to the system, which means the driver is performing no manipulation of the pointer speed. I am unsure of how the 1k refresh rate is tying into your perception of pointer speed: the refresh rate is simply the number of times that the mouse reports it's updated position to the driver. If you have a mouse set at 500hz and 1khz and move it the exact same distance on your desk, both would move the same distance on the screen. The only difference would be the number of times the computer was updated on the position of the mouse.
What you are describing is likely to be unrelated to the mouse, as you have had now two different generations of mice and two different generations of the OS, and you've had issues where the mouse is chaging DPI on it's own AND it's on the exact same computer. If I am to guess, I believe it's switching to one of the middle DPI on your mice. What this leads me to believe is that what could be happening is a USB bus reset. On this computer, how many devices do you have installed on the USB bus? Do you have the mouse plugged into a hub? Have you tested this mouse on a different computer? Do you have the latest northbridge or USB controller drivers installed? You can try burning the current profile to the mouse's memory on the G500 as well, which might prevent issues where the bus flickers and SetPoint is unable to properly reapply the pointer settings to the mouse.

I have got a problem with the G500 aswell.
When my pc is idle for a while i have problems with it. It seems that the left arrow key is switched on and its keeping pressed.
And before my pc is idle i can't click anything on my taskbar, it just doesnt lite up.
I have a G5 aswell without any problems. When i reconnect the G5 after having the problems with the G500 i just restart my pc and my problems are gone.
I run W7 64bit btw.
I am going to bring mine back to the store and get my money back untill there is a good expenation or solution because i do like the speed and the feel of it!

I also have a G500 movement problem.
Its as the mouse moves as normally then slows down dramatically for just a moment (maybe 1/4-1/2 second) then speeds back up again. Its like it just randomly "hangs". Motion is not always fluid. This problem shows itself about every 5-10 full motion horizontal swipes across the screen, so its alot.
I just noticed it for the first time about a week ago. Ive had the mouse for maybe 8 months and my "new" computer 11 months. I had not updated any system drivers of any kind recently (unless windows did automatically without my knowledge, which I dont think it can) and had been just using the windows mouse drivers when I noticed this problem. Since then I installed SetPoint6.x and disabeled "use OS drivers for speed/accel". I tried a few different settings for speed, accel, and refresh with no avail.
MSI P55-GD85 Motherboard
Steelseries mouse pad (that is clean btw)
I also went to MSI's website and installed all the latest chipset drivers for the GD85 and STILL have the problem.

Sorry if this is not the right place, but I am having similar issues with my Logitech G400. It seems to have random changes in both the DPI settings, and also this mouse is so annoying, as every so often it just seems to change sensitivity or speed, just for a split second. It has gotten to the point where I am looking to get another mouse again. I just bought this mouse, and it has been driving me crazy. I thought it might have been a problem with Windows 8, so I reinstalled Windows 7, no luck, the problem still remains. And I have tried this mouse with and without the software installed, I have tried all the settings, DPI settings, polling settings, I have tried changing the sensitivity in the windows mouse control panel, tried it with or without the "enhance pointer precision", etc. I am wondering if it is some sort of software issue or driver issue.. I know others here are having issues with the G500, and I am wondering if the software or drivers used are similar or the same code base at all.
Anyway, hope my post helps.

I've had this same issue for quite some time now and no one from logitech has ever responded. Their LGS 8.40 software is junk but I haven't had the horizontal mouse "hang" or "stutter" as often using it over the setpoint 6.X software. Its ashame since the setpoint software is superior and is not some thrown-together POS that should never have been released unlike LGS...
My problem will soon be fixed since I have just ordered this beauty: http://www.feenixcollection.com/nascita.html
Now thats a real mouse children.
