Severe Windows 10 Mouse Lag

Greetings.

So since I bought my Mid 2017 27'' iMac in December I have ridiculous mouse lag that is happening everyday all day long.

In macOS everything seems fine, while in Windows 10 Pro mouse randomly jumps around, clicking things with right button, hanging, slowing down for ten or so seconds and sometimes just stopping to work until turned off and back on. It can happen up to hundred times a day. Interestingly enough, I had not a single issue with my wireless keyboard whatsoever. I tried two of them. Not a single lag.

So I though, it might a hardware and gone through tree Magic Mice 2. All lag. Obviously I tried reinstalling Windows and drivers. Lag kicks in on clean Windows 10 installation after I install drivers anyways.

I tried disabling all electronics around and my router antennas. And since there're no problems with keyboard I am starting to think it's not a Bluetooth issue.

Everything is up to date and none of the updates either Apple or Microsoft ever fixed a thing.

Are there any people here running Windows 10 on new machines? Any issues or suggestions?

Thanks for reply. No, in macOS everything is brilliant. In Windows 10 it's pretty horrible and absolutely random.

Bluetooth coexistence/collaboration was the first thing I tried. And I am not using wi-fi on this machine, it uses Ethernet cable. I even tried disabling wireless adapter in device manager.

We actually spoke in different topic on this forum about same issue. Topic just went closed.

I've gone through all kinds of router manipulations and the fact that I can't find much people like me and the fact that it happens only in Windows 10 and only with mouse (not keyboard) making case very strange.

As a test, if you have a wired USB mouse, can you run the same test and report the behavior you see? Do not disable the wireless adapter.

Do you have any USBc storage connected to the the iMac? Please also check if BT driver is allowed to turn off the device to save power.

Just tested $3 USB-mouse. No issues with it. Also, in device manager, Bluetooth radio itself had this "allow to turn off" thing disabled by default. I unchecked it on mouse and keyboard as well, but it had no effect.

As for connected devices, mouse lags even if nothing is connected.

I tried that numerous times. If you unpair mouse in Windows it will never pair again. It will say "Try connecting again" or something like that. The only way to pair mouse is to do so in macOS and then, after reboot it will appear in Windows. I believe it's they way it is on newest Macs.

Ultimately I cannot pair mouse in Windows. I click on button to add a Bluetooth device in settings, choosing category where it says about manipulation devices etc., and when I select mouse in the list it fails to connect to it.

Okay. I narrowed problem to Apple Wireless Mouse driver. If I uninstall it, no lag whole day, but no scrolling as well as you might imagine.

I tried drivers from Boot Camp 5.1 and 6.0 with no luck. They won't fit. Also tried Magic Utilities (like third party app), but they use same latest driver that lags. Any Ideas?

Can you right-click on the Apple Wireless driver and look at Properties. Post a screen shot, if possible.

Trying older drivers can lead to new problems.

Does the mouse the show the same laggy behavior when you boot in macOS, in the same environment?

Have you checked if BT/WiFi collaboration is enabled or automatic?

Can you reboot and test? Sometimes I have seen Windows needs a reboot after changing these two settings.

No, it didn't. I tried older drivers from Boot Camp 6.0 also, but they don't fit since the hardware was refreshed it sees.

Use a USB Mouse/Keyboard, un-pair the BT Keyboard/Mouse from all known devices, pair them to Windows first and test and verify. If they work properly, pair them to macOS and test.
