Re: Battlefield one suddenly unplayable

I would run a process viewer, or task manager in Win10 and see how much CPU and memory is being used by BF1 and if anything else is maybe hogging some of your CPU when you are trying to play.  I have run into this before with a background process tying up my CPU when I am trying to play and getting horrible FPS from it...it is annoying as * when it happens to me, so it is worth a look at least to rule it out. 

I have also had a driver update go badly(or just got corrupted) and have to do a clean reinstall because for some reason my vid card would only run about half power....
