Playing the 10hour trial too. Just done playing thru the 1st chapter of the campaign. Apparently you have to buy the full game still in order to play the rest of all the campaign and till the day it release (unless you pre-order digital deluxe or ultimate edition). Played some of the multiplayer matches and i am so hyped with it thus far  *BF1942 nostalgic*

Add me up: AeonixG

P.S. I was able to Max Ultra the Graphic Setting in 1080p with my spec. Not as graphic heavy as I thought it will be 

I'm late but here:

i5-4690k almost same spec as i5-6600k

@Apisfires, your cpu is more powerful. Older =/= less Ghz.
And you use gtx 1070, of course run smooth.

@Hongki what GPU you use?

Considering that BF1 min requirement is i5-6600k (3.5Ghz) and your i5-6400 (2.7GHz), its obvious the lag come from your CPU. BF game eat your CPU hard with their levolution physics. I think your GPU make the min cut.
Try turning off some setting especially AA.
Keeping your PC clean of dust can also fork out some 5-10 fps.

balance is the best. a high end cpu can last you for yearssss..... 
i plan to use my 4770k until 7nm proc 

slap a CM TX-3 on the 6400 and OC to 3.5ghz.
change gpu. i used 7870xt previously to play Grid 2, so i know kinda how weak it is 

OC is a really easy as 1,2,3 things once you know it.
1. Increase the BCLK mhz to obtain 3.5ghz (turbo) (Additional 200mhz should be obtain easily since the stock is 2.7/3.3ghz)
2. Get a 3rd party cooler - Tx-3 is really a good performer for its price. (stock cooler should not be used for OC) - suit your budget
3. if unable to boot into window or shutdown upon entering bios, turn off the power plug, take out CMOS battery for 5 min and it shall reset your bios settings back to default.
4. install hardware monitor/temp. monitor. stress your OC with gaming - should be stable as again, its just 200mhz increase unless you get lemon proc 

well, you only mess with the core mhz and leave other default, 200mhz is a peanut oc. once you get more confident/knowledge, try to get the max OC you able to squeeze from your proc

here a guide to OC 6400 - don't try to increase BCLK as the guide tho - later fried
