Turning around the office lags in Fnaf 1

[MisterJ143]

So...It's my first time playing a FNAF game and I was trying to beat the 20/20/20/20 night and it's just then that I notice (probably because the other nights were easier) that, on Fullscreen, I move SLOWLY in my office with the rest of the game not being slowed down but in windowed mode there's absolutely no lag.

I already used my task manager to make FNAF 1 into my top priorities program but no result. I tried to use windowed mode in my advantage by trying to adjust window but it resulted in black border line around the game. However, when i shut down/restart my PC, miraculously the game sometimes runs fine on fullscreen (with a tiny bit of lag sometimes) but it vanishes as soon as I leave the game (or use my monitor too quickly to check Foxy prior to look around the office...)

And those who want to know, yes my computer does have the needed requirement to run the game (or else I wouldn't have bought it). So now my only option is to beat the most diffcult night in windowed mode which is kind of unbearable but I can still deal with it somehow.

I would gladly appreciate if anyone could help resolve this (because it's been bugging me for multiple days and I don't want to buy other FNAF games if I have a problem with the first one...)

F11 or hold Fn and F11 if the Fn lock isn't on.
