I just wanted to share this for anyone else who might have experienced annoying lag when gaming on their HP OMEN "gaming laptop". I've found that you will never get the Synaptics Touchpad driver/software package to NOT interfere with your 3D gaming experience. I wasted a bunch of time following all the suggestions I found on this forum and elsewhere; including rolling back to a a pre-Win10 driver, and none of it worked. I did find a solution though; dump the driver.
A simple example of the problem is if you're playing Minecraft and want to walk and look around at the same time; pretty basic ask for sure, but the stock driver setup on your "gaming" laptop will not let you do that.
To fix this you must go into the "Device Manager" tool, go to "Mice and other pointing devices", double-click the Synaptic touchpad driver, go to the "Driver" tab, and select the "Roll Back Driver" button to remove it and just use the basic "PS/2 Compatible Mouse" driver.
You will loose all the fancy multi-touch features of the touchpad but it seems Synaptics or HP (not sure) doesn't have the technical chops to make a driver/software package that will let you have both productivity and gaming features on one of their laptops: so you must choose. If you want to be able to play a game without an external mouse you'll need to keep it simple and forget the fancies.
