Multiplayer. I haven't fully tested single player.
If the game doesn't stutter or turn in to a slide show, I get an odd sensation of rowing a boat (fast, slow) or the movement of the charter feels like a penguin waddling. (running is fast then slow)
Prey also felt weird but couldn't put my finger on it.
But BF1 was really really broken. If it wasn't the CU or Nvidia drivers (or a combination of both) then it is my hardware.
I'm sure non savvy PC owners would think they have a broken card and would be doing an RMA.
Over the weekend I tried, a clean install of windows and my hardware at stock and still the problem persisted.
Early days yet as I only played a few maps on the Anniversary Edition, but despite performance generally not being fully fluent it was much better than the CU.
Amiens is still the worst performance, but I could see other players complaining in the chat about performance too and lag.
But the kind of performance I was seeing is the kind where your hardware isn't fast enough for the game.

This is the weird thing. I was running the CU since it launched and never had any issues with my 970 and non Gsync display.
Two weeks ago I upgraded to a 1080 and a Gsync 1400p monitor. The 1080 came first so I put that in to existing PC and gamed on it at 1200p for a bit. This is on a PC running the CU and had no issues.
When my monitor arrived I hooked that up and since then I've had nothing but major issues in BF1.
I did overclock my CPU and RAM. But these where tested thoroughly and have stood up to hours and hours of gaming and use since and haven't fallen over. And as mentioned I tried it at stock and the problem persisted.
One thing I didn't try was turning Gsync off yet.
