Hi sultan_4,
First, with BF1, your CPU will not be powerfull enought to throw 200FPS while processing the game...
Then disable DX12 if it's on.
This is the only game, that i've seen, needing 8 threads to run smoothly without stutturing.
So to "limit" the CPU bottleneck, max every setting you can at an higher resolution. That will put an higher load on the GPU and "relaxe" the CPU.
Also 8Gigs of ram is becoming the low limit of what's needed nowadays.
Rodolphe.
