open the patch you downloaded then choose limitted ? or just reinstall your nvidia drivers then launch TF2 with -fullscreen and -freq 75 or -refreshrate 75 ( i don't remember but i think it's -freq )

refresh rate launch options dont change anything, reinstalled nvidia drivers and it didnt change anything either
the patch is as useless as it was for me before

ok honestly this is getting retarded, i put -autoconfig in launch options,
launched the game, removed it and launched it again which somehow fixed the game not being fullscreen
(of course 75hz still didnt work but at this point getting the game to run at fullscreen would be enough)
this worked for a few hours until now when my game just out of nowhere went noborder again
i simply cant get my game to run fullscreen at all, i beg you to help
i can provide hat

Is your monitor 75hz? If I'm not mistaken, 60hz displays can do 75hz because that's their vertical refresh rate, but only if you run the program at the a horizontal res that matches your monitor's vertical res.

my monitors 60hz i overclocked it, idk

I don't know much about monitor OCing, but yeah, I think you're going to have to run tf2 at a lower resolution to do 75hz, sadly.

it really weird because until now it worked without a problem, it just all of a sudden happened
ever since i installed that windows 10 update anyway

honestly its the weirdest thing ive ever experienced with tf2, its basically fullscreen...
i can change monitor gamma without a problem
but as the pirate that i am i also get a windows activation watermark which only shows ingame if you have windowed on
so basically my game thinks im running fullscreen
but im actually running noborder
with all the terrible input lag and shit

try creating a custom resolution on the nvidia panel to match what you want (res and hz)

thats the way i got 75hz in the first place, whatever though
thanks for the help everyone, at this point im just going do a fresh windows 7 install instead
