I am having these problems too. I am using an Nvidia 1080 Ti. I've tried fixing it by:
-Capping Framerate
-Disabling G-sync
-Downgrading windows 10 to before creators update (version 1607, clean install)
-Updating to Windows 10 1709
-Tried Nvidia drivers 387.92, 388.00, 388.31
-Changing pre-rendered frames from 1 to 3 and vice versa
-Game installed on SSD and HDD, no difference
-DX12 (worse stuttering, but DX12 typically has issues on Frostbite)
-HPET on and off, no change
-Turning off all my overclocks, no change
-Game mode on or off, no change
Nothing seems to help, but I did discover it happens when loading new assets (first time loading a character model, sound, texture, etc.) I noticed when monitoring GPU usage that GPU usage drops to 0 every time it stutters and then back up to 100% afterwards. It's definitely this game, because Battlefront 1 works great on the exact same setup. I would love to help the devs figure this out so I can enjoy the game.
Intel 4790k 4.5GHz
EVGA Nvidia 1080 Ti 11GB FTW3
16GB 2133MHz DDR3 RAM
Same here! Only thing that helped a little bit was, turning V-Sync on and capping the FPS. It stops the stutter a little bit, but it's still unplayable on multiplayer.
Hope they'll see these posts soon and fixes the bug.
