i did all what saying on this forum, nvidia and on other sites, but no one method does not help me, and recently on geforce forum, people find problem, it's Creators Update and new driver nvidia 38x.xx.
I reinstall my windows to anviersary update and o god, no more stutters in games and bf1!, If you dont wanna reinstall windows, wait patches from microsoft and nvidia, but i dont how much y need wait is
guide where get windows and how reinstall wrote man on geforce forum "barlonemaximus":
Use RUFUS (search it on google) to create a bootable USB with the iso you downloaded (remember to set UEFI and GPT in rufus). If you don't understand what is UEFI and GPT simply search on youtube "how to create a bootable win10 usb with rufus" and just do what they do.
Restart pc, enter in boot options and select your usb drive
At the end of windows installation you will be asked to download and install updates (they ask this just before showing desktop), press SKIP (very important).
Under "manual driver search" select your OS (win 10 x64 for example), your GPU and your language. Then press "start search" and you will have a list for all nvidia driver versions for your os+gpu. select 378 version, download and install.
P.S If you do a clean windows installation you will lose all your data on the ssd (i'm guessing), so make sure to backup all your data and bla bla bla. Don't worry about windows license, if you have bought your laptop with windows 10 your digital license is linked to your mobo.
Good luck, and, sorry for my english, he so bad. I hope it's help all who have stuttering after update
