I'm beginning to think it's more to do with the GeForce Optimus switching GPU's. The sticking is more prominent when the indicator is switching between GPU's. Which kinda explains why when I'm using software that uses the GTX660M the sticking pretty much stops.
Ok guys, an update. Fresh installed 8.1 via UEFI boot and let windows update do its thing. Upgraded to 10 via iso with NO issues. Activated fine, clean installed 10 via legacy BIOS rather than UEFI and everything is working well!
I haven't really noticed major mouse lag, the only times I have clocked some sort of lag it always seems to be simultaneous with the HDD indicator being continuously on for 1-2 seconds.
I installed the Intel drivers and removed the hotkey drivers and it still sticks.![]()
Even after an upgrade it assigns a generic key.
That can be very likely. If you google NVIDIA Optimus + Windows 10, you can see a lot of people having issues with it during the Windows 10 Preview. Is it possible to change the Optimus IV's to only use the NVIDIA GPU, completely disabling the Intel GPU? I know it's possible on Lenovo laptops.
EDIT: Also not to mention that Clevo hotkey has not been specifically developed for Windows 10 yet. That software is just a nightmare. Otherwise, have you tried installing the latest Intel GPU driver? https://downloadcenter.intel.com/do...hics-Driver-for-Windows-10-64bit-3rd-Gen-BYT-
Wouldn't be surprised if this was a hotkey issue.. It has always been a dodgy piece of software. If you do a google search for 660M NVIDIA Optimus Windows 10, there's almost no results, so it doesn't seem like other people had any issues with the Optimus system itself. Hotkey is required to switch between Intel GPU and the NVIDIA GPU, right? I know some vendors, like Lenovo, has added support to switch between GPUs in BIOS and the way it presents itself to the OS: View attachment 7000
Also, did you try and do your install, while UEFI is enabled? It seemed to solved Jay_P's issues.
EDIT: Good work, btw![]()
No, didn't try UEFI. I'm trying to keep things as simple as possible! I can't explain why it works for Jay_P, perhaps our different CPUs, SSDs/HDDs, installed RAM (RAM type) make a subtle difference?
I'm absolutely convinced it's a driver issue, almost certainly Hotkey. This laptop has run Windows 7, 8, and 8.1 without issue so I know it's not hardware.
It seems your hardware is almost identical:
