Just throwing my complaint toward DICE too:
FX 8370 OC at 4.5Ghz x8 All cores running at max Freq. from BIOS. Just to be clear, DICE RECOMMENDS (so not the MIN.)on the Box a FX 8350.. (Also no other game even comes close to 90% Load on this CPU- e.g. BF4 at 140 res.scale runs at CONSTANT 100fps with CPU only at 50-60% Load).
MSI 970 Gaming MOBO
Gtx 1070 (8GB VRAM)
16GB RAM
GAME IS ON A NEW SAMSUNG SSD
8 POWERFUL CASE FANS (I even made a hole in one panel to install one) all Blowing and Sucking Air from all Directions-the result is: under 100% load the CPU only reaches 46°C (114 Fahrenheit) and GPU 58-59°C (137 Fahrenheit). The VRMs dont exceed 60 ° either.
All this powered by Cougar GX 800w PSU - this baby can handle two overclocked RX 480s in Crossfire like it is nothing.
PC WAS BUILT IN January 2017(specifically for Bf1), so all components are almost new. (Only changed two RX 480s with the 1070 in February cus crossfire\SLI sucks on most games).
On a 1080p 75hz Monitor I get:
(THIS ONLY HAPPENS IN MULTIPLAYER, the SINGLE PLAYER runs perfectly).
mostly 50-80fps but drops to 30 are very frequent (at least 2 times a minute depending on what is happening) , but that sound better than it is, because when these 30-ish fps dips come, first the image STOPS for 0.5 seconds or more. It happens randomly, but of course more often when I’m trying to shoot someone who is moving or grenades explode or ALMOST EVERY TIME THE GAME ZOOMS OUT\IN after death.
THESE DROPS \SKIPPED FRAMES happen with DX 11 AND DX 12 equally. Only I play DX 12 because the average FPS is a little higher. (with dx I cant even reach the 75hz my monitor has).DX12 uses better AMDs multicore.
Even if I cap the fps to 60fps (I never use Vsync, either a user.cfg file or the menu option) the Frame Drops still happen often although the CPU usage is now only 70-80% (msi afterburner readings).
I normally play at 125% resolution scale (so not even 2k) but the drops happen equally at 100% res.scale or 150% or higher (although with 150% the average fps is lower cus the gtx1070 is at 100%, whereas with 125% it spikes between 60-90%):
I also tried High or Med. settings (I usually play at ULTRA) and the same problems occur (it is dumb to think that making the game even more CPU dependent would help).
It has ALWAYS been like that since I bought it Dec.2016 regardless of the Bf updates, Windows 10 updates or Nvidia drivers.Also using the custom .cfg file with all those things disabled only helped a very tiny bit.
THAT BEING SAID, these drops don’t happen on all maps equally:
On the SINAI DESERT map it almost never happens(even with 64 players online).
Also SUEZ is almost as good!
Monte Grappa, Ballroom are mediocre.
Amiens and Argonne are THE WORST BY FAR!! NOT ONLY HUGE AND FREQUENT DROPS BUT ALSO LOW AVERAGE FPS (ca.10-15fps lower than the others).
DICE please, this is your flagship game this is not acceptable. I would like to buy the Battlefront 2 when is comes out, but if users will report same problems, you will not see me in stores but on tor*ent sites (yeah, playing only singleplayer is sad, but I’m not spending another 60€ on something that does not work as promised\advertised ever again.
(I also got tricked into buying titanfall 2 cus it was said to support CROSSFIRE but it only does so in Singleplayer 
).
