Hi i had some problems with lag not konstant lag but Frame Lag.
To make sure you dont have a certain feature turned on that gives you lag tjeck this
In game mode Push: -> Esc -> Video -> Reduce input lag (If this is turned on without any reason, turn it off it will give you alot more frames and reduce lag spikes, if you are in doubt if you should turn it off then just try it you can allways turn it back on if it is a must)
:boxing: Happy lvling
Yup, I've turned this off now and my frame rate has doubled. Much smoother :D
