can graphics drivers be the cause of terrible mouse lag in a two-monitor scenario

[TTimR]

I'm running Windows 7 x64 on an ASUS P8H67-I DELUXE m/b, with Intel HD graphics (latest drivers, 1/30/2015, 9.17.10.4101).

Although a Logitech USB-dongle wireless mouse works OK, a Microsoft no-dongle bluetooth-radio "Sculpt" mouse has horrendous lag, but is noticeably worse on the left-hand monitor. I've upgraded the mouse drivers to the latest as well.

Can graphics drivers possibly be implicated in this problem? The "Conflicting Device List" says "No conflicts."

I've seen other references to this two-monitors-mouse-lag problem on the 'net.

The version of Windows I have is 64-bit, but I see only 32-bit versions of the Intel graphics driver. Does it matter?

Hi Mrblint,

I'm just following on this thread to ask you if your issue was resolved with the information provided above. Regards,Hellen.

I have not yet installed. Will I be able to roll back if the driver should happen to create any problems? Should I make my own system restore point, or does the Intel installer create one?

Hi Mrblint,

For sure, you can uninstall the driver it won't be a problem; as a recommendation would be better if you create a Windows® system restore point. Regards,Hellen.
