With Analog controllers you send tons of signals to the computer which
can slow down the game, so thrustmaster sells a port to fix that, but I
think Direct X 5 fixes most of the problems by itself, under direct
input.

Is this true
Would I benefit from the Wheel port
Has anyone tested this stuff

Thanks In Advance

Thanks for the info,

When I run moto racer I get a slower response with analog steering more
so with the analog gas and brake, I thought that was improved by Direct
X 5.o  

Everythings seems to be fine as far as control, so I will proably push
off the purchase.  I will also experiment to see if I can still see the
problem after the new Monster 3d.

A dedicated gamecard (such as Thrustmaster's ACM) is not designed to
handle the "polling" load.  And I highly doubt that gameport polling is
slowing down games.  The real purpose of the ACM card was to provide
accurate data to the program when it polls the gameport.  The 2 real
major issues with gameports on soundcards are bus speed and thermal
drift.  The ACM is adjustable so that one can get an accurate reading of
the gameport with any speed computer.  It is also built to a much higher
standard than the gameports on most soundcards (or even dedicated
gamecards) to elminate as much as possible thermal drift.  Thermal drift
will cause a gamecard/port to report different values as the inside of
the computer heats up.  The ACM also had 4 ports (2 dual ports).  None
of these issues are addressed by DirectX (at least to my knowledge).  As
a matter of fact the calibration routine in ProPanel (Thrustmaster's
applet) may be finer and more accurate than the ones in DirectX.

Some people swear by them and others consider them to be snake-oil.  I
think that there is an improvement with an adjustable dedicated gamecard
over one built into a soundcard.  However, if you aren't experiencing
any "twitchy" or "sloppy" controls with your current game port I wouldn't
recommend you running out and getting one.  But if you ever think your
controls are too sloppy or find that they change over the course of
runing a program, I suggest you look into one.
