Hi All, I'm working on a game prototype in Unity, simple 2D platformer gameplay, using the keyboard as the primary controller. The problem i'm continually running into no matter what i do is some amount of input lag from the keyboard. Using the FPS walker script as is ( and later modifying it to make sure that the delay isn't cause by the 'if(grounded)' check ), i sometimes get delays in jumping. It's a few hundred milliseconds, but it's definitely noticeable in my game. Is this a Unity core issue, that the engine lags a bit and that affects input? I thought for a while that it was just on my netbook, but after i sent the link to a few friends, they also mentioned it's a bit annoying and basically makes the game unplayable at points. I really like Unity, so i'd hate to have to leave it for something like XNA for this game. I'm pretty technical ( C++ programmer by day ), so please don't hold back in any answers Game is up here and the controls are standard Horiz Axis and space for jump. Note that on some jumps, you hit space, but it doesn't respond immediately or at all.
