biotouch.exe
 

Is this actually being used? I see it runs by default.

On the HTC Touch I had, I disabled the TouchFlo stuff and biotouch.exe was one of the files I "eliminated" for memory and speed.

Has anyone done any research to see if this is actually part of TF3d and/or needed?

I notice quite a few other processes like RSShub and Opera items are also starting with the OS.
