Surface Book 2 Trackpad and Keyboard Lag

I too have the same problem.  Much worse when on battery but have to say it's maddening on a machine that cost this much $$.  My old Surface Pro 3 was a much more pleasant experience to use and cost a whole lot less.  

I hope MS has something coming soon to fix it.

Thanks for posting this.  I know that this is what Microsoft initially suggests but unfortunately, this is not the answer.  The problem has something to do with power settings combined some kind of issue related to display drivers.

Follow these steps to work around the scroll lag issue:

• Type in Mouse & Touchpad into the search bar.
• Roll down till you find the Use a two finger pinch to zoom setting.
• Change the feature from On to Off.

The downside to this fix is that, once you make the change, you will need to use the touchscreen to pinch and zoom.

Hopefully, Microsoft will address the trackpad lag issue with an update to the touchpad driver or firmware in the near future.

I have been experiencing this lag issue as well on my 15" Surface Book 2 and while researching the other day came across a solution that someone reported fixing the same lag issue on the Surface Pro 4. 

The problem seems to be an issue with power management. I don't experience the problem while connected to power or at max battery performance. Running on battery saver also alleviates the lag. The keyboard, pen and trackpad are all responsive now while maximizing battery life and overall performance is in line with the Recommended battery performance level. 

To clarify, here's my experience:

1. The worst touchpad and keyboard lag is when on battery life and the performance slider is set to either "Recommended" or "Better performance."
2. When on battery life, moving the slider to "Best battery life" or "Best performance" alleviates much of the lag, but not all of it.
3. Much less often, I also get the lag when plugged in. During those moments, moving the slider to "Best performance" seems to alleviate most of the lag.

So, it definitely appears that whatever Microsoft is doing with the power adjustments is messing with the input queue somehow, since by all accounts this affects the keyboard, the touchpad, and the pen. Assuming that Microsoft's engineering team is aware of this issue, there has to be hope that they're working on a fix and that it won't be terribly difficult.

But it really does need to be stressed that this issue makes the Surface Book 2 very difficult to use efficiently and wouldn't be acceptable in a $700 notebook, let alone one that costs $3,300.
