Strange fps drops in Battlefield 1
I am having a problem with BF1's FPS. It runs around 25-30 fps when I join any server, but when I alt-tab and open the game again, it suddenly runs at very good 60-70 FPS before slowly dropping to us...

I ran temperature monitor, and it seems heat levels are same for both bf1 and bf4, however 4 doesn't lag and 1 does. So, heat doesn't appear to be a problem.
What are these temperatures? (GPU & CPU)

Regarding nvidia settings - I tried to set bf1 to maximum performance, but it had no effect. In fact, fps drops are the same whether I use nvidia or integrated GPU, so it doesn't appear to be a GPU problem either.
So you did set BF1 to use your NVIDIA GPU as describe in my last post, and you kept it that way?
I ask because setting it to maximum performance mode is also an option inside the NVIDIA control panel, but that is a completely different thing.
Please preform a clean boot and test the game in clean boot mode.
I downloaded another temperature monitor and looks like GPU temperature is in fact involved in problem. It reaches about 72-80 °C when game is open but after alt-tab GPU cools to around 60-65 °C (with big FPS increase), and then heats back to >72 °C when game is reopened, causing FPS to drop. Temperature fluctuations seem to be independent from resolution and graphics quality (ranging from 60 to 80 °C on any setting), but of course at same temperature, higher resolution yields lower FPS. Do I need to physically cool my laptop down with external fans, or this problem can be resolved through OS/BF1 settings?
Regarding GPU settings - yes, I set BF1 to use NVIDIA GPU.
Forget my last remarks, should read carefully.
GPU boost will throttle the GPU at this temperatures.
You should clean or let someone clean your Notebook fan system.
There are guides easy to find with google.
Is it very hot in the region you are in?
