    Yeah I was just going to give an update. :D

    Today I tried it plugged in and there's no signs of throttling whatsoever.
    I tried Divinity original sin 2 again even with a more demanding configuration and had a steady 40-45 fps all time.
    Obviously I tried best performance too but it seems to me the machine gets too streessed up that way for a prolonged use. Not mentioning the fan noise is only bearable if you live alone and play with headphone on.

    Hello all. New Surface Book 2 owner for the past couple weeks and love it except for the battery drain issue. Battery will drain even while encoding on Adobe Premier Pro 2018, so it isn't just a gaming problem. It doesn't drain MUCH, maybe 1-2% per hour, but it would be nice if it drained a lot less. I found the only 100w USB adapter.

    The Book 2's adapter is 102w but I found out that it will only supply 95w to the computer. 7w goes to the stupid phone usb port. I don't know why they did this, especially if it's not in use! 100w will give it that 5 extra which would be hugely significant. Am I missing anything here? This power supply is $79 and made by Wacom. It is expensive as heck but still cheaper than Microsoft's charger. I'd like to own a second charger anyway so I'm thinking of going this route, but I won't bother if it won't help with this issue.

    Edit: Just noticed my signature says Dell Venue 11 Pro i5... rofl. :D

    @jyan_osu I have to correct myself: I'm here in bed now, I'm plugged in and in Better Performance and the machine gpu still throttle like hell after like three minutes of playing, passing from 40fps to a steady and unplayable 15fps.

    I have no clue what's going on. Does this thing knows it's on my lap instead of a desk so it purposedly reduces the performance to prevent getting too hot?
    I'm out of ideas how to solve this problem.

    Working with Geoff, a Microsoft engineer for the Windows Mixed Reality team on my Samsung Odyssey review using a Surface Book 2. I heard of many great improvements for WMR with the Spring Update.

    Looks like I was able to create a case of lag with it though and they're looking into it. He was able to duplicate some of the performance issues and told me to hold off on updating to the Spring Update in the Insider's Program.

    No, it shouldn't. I don't know why it's doing that. I haven't had any issues with mine in that regards to playing games and I've gone through a gamet of Steam games myself.

    What NVIDIA driver version are you using? 388.08 seems to be the one recommended by Microsoft currently.

    If you just got it, I'd do a complete refresh from recovery as well. I was told using the recovery image from https://support.microsoft.com/en-us/surfacerecoveryimage would eliminate a lot of variables compared to using the factory reset option.

    You could try updating the NVIDIA drivers, see if that helps.

    OOOH. Try this.. I wonder when you unplugged it if it's defaulting to using the Integrated GPU instead of the NVIDIA GPU.. set it up to use the NVIDIA processor like this:

    Thank you for the info. It says that the The Surface Book 2 with USB type-C accepts up to 20V via the USB power delivery 2.x/3.x standard. The 102w PSU 15V@6.33amps (95 watts) + 5V@1.5amp which is what I thought when it comes to the wattage distribution on that device. USB PD allows a maximum of 20 volts at 5 amps (100 W). IDK if that wacom supply is a waste of time or not. Only one person used it on the 13" and was able to charge at full power, so that's comforting.

    Nevermind. It's a total waste of time to even try a usb-c connector that supplies 100w. My kil-a-watt meter is telling me the Book 2 is drawing 100w from its PSU as it is. The 95w thing I read must only apply to Book 2 13"...

    I'm using the Nvidia GeForce experience to tune the game.
    I updated the drivers and it seems to be throttling less frequently but it's still throttling nonetheless.
    I will have to investigate further: I was playing fine for several minutes after the updating, then I closed the game and reversed the clipboard so I could play more comfortably and then after a few minutes the throttling happened again. Don't know if it's related.

    I also reminded I'm on the latest Windows insider build, so who knows if it's that?
    I might try a fresh windows install tomorrow to see if things get better although It means I will have to install and setup everything again. Ouch!

    Edit:
    Prior to refreshing windows though I'm going to install The Witcher 3 and see if that has important frame rate drops too. Who knows, it might just be that game...

    @jyan_osu today I installed The Witcher 3 and investigated this issue further…

    The game went well for something like 3 minutes with a steady 40-50fps and then during a cutscene as usual got down to 10-15.
    This gave the opportunity to formulate an hypotesis though: I try to play with the clipboard reversed 180° facing outwards and it seems to me the computer throttle the cpu down after some time in that configuration. More, if you quit the game, reverse the clipboard to laptop mode and then start the game again the same throttling behaviour occurs. You have to restart the machine if you want to run things smoothly without having reduced performance.
    In fact I also tried having the Surface Book in full laptop mode, restarting the machine, run Witcher 3 and this time I played the game for half a hour (cutscenes included) with zero frame rate issues at all.
    Playing this way won't be as comfortable but well, if it works...
