I've not had the guts to move the network slider, I didn't want to upset anything!
any tips?
copied this from battlelog forums;
3) Improve Network Smoothing
We have made some improvements to the ”Network Smoothing” functionality that you can find in the OPTIONS>GAMEPLAY menu. The Network Smoothing slider governs a group of settings that aim to produce a tighter multiplayer experience based on your specific packet loss situation.
If you’ve been experimenting with the Network Smoothing slider earlier, it might now yield better results. If you haven’t tried it before, please explore this setting and set it to the lowest value you can without experiencing graphical glitches in the game. By setting it lower, you can get a tighter multiplayer experience, depending on your specific network situation.
I have read on these forums also, set at 50% then experiment from there.
hope this helps
