rec.autos.simulators

I downloaded CART racing reality from Microsoft.  When I run it it tells
me 'the sound device does not have a DirectSound driver'.  People tell
me I have to load DirectX 5.0 and that will fix the problem.  I'm
running Windows NT 4.0 and DirectX 5.0 is not compatible with NT 4.0  Am
I out of luck or is there a solution ?

Any tips  will be appreciated.

 You need Service Pack 3 in order for this to work.

You need DirectSound compatible drivers - go to your OEM
web site and check there.

D3D hardware acceleration under Windows NT 4.0 SP3 is software emulated
(read as slow).  Under NT 5.0, it will be actual DMA.

The joystick is a weak link under NT.  this is for analog joysticks (the
vast majority).  A digital joystick should be no problem to NT or 95.

NT is hands down more stable than 95.  NT 5.0 is trying to become more game
friendly, but this will still not be DOS game friendly.

Neil,

RAS has been my newgroup of choice (next to
comp.os.ms-windows.programmer.nt.kernel-mode) for many years.  I read more
than I post, but I do occassionally post.  I haven't commented much about
CPR mainly to avoid confusion.  I work at Microsoft, but I have nothing to
do with CPR.  So I let Dean and the others answer the CPR questions as i am
not in the know with that product.

About joysticks.....

From personal experience, I have found that Windows NT 4.0 can handle a two
axis joystick adequately.  A three axis joystick, so so.  A four axis
joystick (flight sim - one joystick for flying, another for throttle, plus
rudder pedals) is not that accurate.

The Windows NT 4.0 joystick driver could 'maybe' be optimized.  I was going
to toy with it, but never did because at home I run Win95 for games.  Since
NT 4.0 Service Pack 3 only emulates hardware acceleration for D3D, what's
the point... :-)

When NT 5.0 becomes more a part of my life, I might look into how well the
joystick works.  By that time, there might be USB steering wheels or digital
steering wheels.  Either would be much, much faster than analog wheels (by
faster I mean how long it takes to determine the wheel's position).  If I
can gain any speed out of the 5.0 joystick driver, I will find a way to get
it posted with Microsoft's blessings.  However, they are striving to make NT
5.0 more 'gameable' (I just made that word up...) except for DOS games.  I
doubt if NT will ever be DOS friendly.

The video whould definitely be faster, however, as hardware acceleration
will be hardware, not software emulated.
