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...

Community AdminIt can help to run the Resource Monitor when you play, you can tab to that and see what part of your system is under strain.
In Windows Search type in Resource, and you should get the option pop up. Then you can check the various system usage.
Heating issuesand throttling related to it can definitely be a problem. You may want to run a temperature monitor while you play, and if you are seeing high heats, check your ventlation/cooling.
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.
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.
Honestly, I am completely lost. I've probably tried everything - creating task to refresh windows cache, unparking and parking cores, tweaking power options, even using different versions of nvidia drivers, yet none of those manipulations gave any improvements whatsoever. Alt-tab briefly boosting fps makes the issue even more ununderstandable. Could it be that this problem is completely impossible to fix?

What are these temperatures? (GPU & CPU)

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?
Have you tried to run on the power adapter directly? A battery might have a reduced power output curve to save energy. BF1 is a much more needy process then just about anything you can name so it should run a little hotter / worse then all others too. But sufficient cooling will keep the temperatures within a acceptable range it will just cap the FPS when the process is heavier then the cycle can produce (calculated in FPS 1000ms/s). You probably do not have any memory temperature probes that could shed some light on those specifics? Also i would not expect too much from a GTX960-mobile GPU when it comes to BF1 but 30/35FPS on low should be a possibility?
btw you removed all power and clock tweaks and changes yes?
[quote] Could it be that this problem is completely impossible to fix?[/quote] Can you upgrade the CPU?
I don't think I can run my PC directly on power adapter, as it has non-removable battery. Best FPS i could get in BF1 was 40-50 on low settings and 1024x768 resolution, but its barely playable due to how blurry the picture becomes.
I did not do any power or clock tweaks except setting power management to maximum performance. Unfortunately, I cannot upgrade my CPU now.
External cooling will only reduce the heat and with that the CPU behavior it will not increase the maximum framerate that you see when the system is actually cool enough.
Ok a triple-fan 1080Ti is cooler then 80 deg but its not a bad temperature for a GPU. The CPU however is less comfortable with anything higher then 55 Celsius. all being a small form factor machine with low power components makes laptop/ sff systems in general less suitable for high-end games. Also you have all blur settings disabled i hope as these will make things blurry even at 1600x 2540pix?
