Ive a Logitech non ff wheel from 1998 on the Gameport. This wheel has a
digital analog converter receives pot readings which is then interpreted by
the Logitech digital protocol (drivers).
Im told it does this so that it bypasses the inefficient Gameport which is
relatively poor for sampling pot values.
I am interested in finding out just how much more precise the software
driven wheels are compared to a generic device.
If for example we had an analog wheel with the same calibration range as
Logi, then how much more precise is the Logi wheel.
IE: Does the Logi wheel have its pot values sampled more often than the
gameport wheel. If so, by what sort of percentage.
Id luv to know the situation here. I would hate to build a generic device
which is physically more accurate (better wheel rotation, longer pedal
travel etc..) only to find it actually gets less grip in game bcos its not
using drivers.
Also,
From what i gather the USB controllers offer greater precision and
smoothness compared to gameport devices.
But just how much more precise is the USB.
IE: how does the pot sampling rate compare to a gameport device
Is the actual latency time less (reduced deadzone) ?
Now for the second smaller question on optical pots:
In what ways is the optical pot superior to our humble old potentiometer for
precision.
Does it have any latency issues ?
Does it offer more precision, if so, why - (higher resolution than pot?)
and is a USB interface needed to take advantage of the greater precision?
Thx in advance,
