[QUOTE=Mustang;495609]On the two occasions this was confirmed in the past it was said to be raw input, but whether this is just unreal’s version of raw or an aftermarket custom coded by Dann with an exact one-one mapping and zero latency version of raw I do not know.
But it would be nice if the floaty/laggy/unsmooth issue could be investigated further again.[/QUOTE]
Regardless of what has or has not been confirmed in the past…
There is no denying that the mouse movement feels just as awful as all other unreal engine 3 games.
The rare exception is when you are around the 250 - 300 fps mark it starts to feel better but no way its not got smoothing or something on there because doing the flick tests my mouse never lands in the same place when moving at different speeds.
IF this is not a mouse input issue then they should look at frame timings and how often the game recieves the mouse input / calculates. if its only calculating it per frame and the frames are all over the place latency wise that COULD explain why it feels inconsistant in some circumstances but it still does not explain the 1:1 ratio on 800dpi optical mice that have no issue on Source, Quake, IW and ID engines… (bar titanfall that has some of the worst mouse movement of the modern age!)
