I tried sweetlow's newest windows hidusbf and mouse rate changer problem, I cannot seem to get my WMO above 300hz stable. But can change to 250 stable.
I tried to follow the instructions above, enabled test mode and even booted with digital driver signature enforcement OFF.
Clicked hidusbf and installed the software, restarted (again) into digital driver signature enforcement OFF. Selected device, clicked filter on+select 500hz, and click restart. Nothing seems to be able to get my mouse above 300hz stable (test with mouseratetester: http://www.softpedia.com/get/System/System-Miscellaneous/Mouse-Rate-Checker.shtml)
Anyone can find out why I am experiencing this? Maybe my IME3.0 is broken or something?
I'm just actually pretty sure your laptop is at fault. I have polling issues on mine too. Could be the lesser components or more strict power saving techniques typically associated with those that do this. I haven't experimented around with it much, but there's a plethora of power saving features you can kill to elevate your polling on a laptop, but that won't really be worth it. You can try some harmless stuff first to see how it improves it though: Take out the battery and draw from the AC exclusively. Use the high performance power plan. Disable some CPU power saving stuff (parking, C-states, whatever). These don't require much time or effort and should be good indicators for whether performance is the problem here.
G502 and V8 works 1000hz on M15x
Core parking is disabled and the battery is not used
Cpu in the windows power manager (minimum 0% and 100%) - cooling active
Unparked cores when plugged in
It worked once on 500hz but I was never able to attain the polling rate again.
Well that changes everything doesn't it. Is that on the same port and registered to the same host controller (device manager -> devices by connection)?
If it is then it just doesn't make sense. Since you can set poll rate your Windows is accepting the filter driver and from there I can't see what's possibly the problem. I guess you can look at this:

It could also be some strange quirk of your USB controllers that just don't do full-speed polling for low-speed devices even if you try to trick them into it.
If i have such problem i:
1. Take other mouse which 100% overclockable on other PC and test problem PC.
2. Take problem mouse and test it on other PC.
3. Disable legacy (PS/2) mouse and keyboard emulation of USB devices in BIOS. But BIOS of notebooks usually hide this (and almost all other) option by default.
Somehow it works at 1000hz now, dunno why. Stable @1000 (920-1000).
I did restart a few times here and there though, along with sleep/hibernate.
