rec.autos.simulators

you can probably tell how desperate I am when I'm posting to web
forums 8-P, but I have a problem I have come across driving GTR
online.

Thanks in advance,

uwe

######################################################################
I am having strange MP problems in GTR: every five to ten seconds or
so, the view will "twitch" ever so slightly when the game synchronises
the online session. Sometimes, the viewing angle will change and snap
back, at other times, the car will accelerate or move about the track
a metre or so (which is usually fatal when entering a corner on the
edge ;-)

I've tried setting all kinds of line speeds, from modem to dsl, but
haven't been able to get rid of this symptom.

xp2400+, geforce 4800 se (128mb), 512mb ddr ram
nvidia 61.xx drivers (latest version), win98se, sblive! value,
tsw2 wheel connected to the gameport.

connectivity is of course 128/768 kbit, sorry for the mix-up.  The
windows machine sits behind a linux gateway, connected over 10mbit/sec
ethernet.

for other players it's reportedly "smooth as silk", even over a modem,
and ping times are in the low 100's usually 70-80ms,
sometimes better).

Frame rate is around 30-40, depending on the track.

The effect is visible in both semi-pro and simulation sessions and in
races with just a couple of drivers or a dozen.

    GC is suss, win98 is suss, sblive value is very suss as is the gameport
these days. All that stuff is well out of date, especially live/gameport. I
remember some sort of issue with GPL with reguard to online and direct X vs
Papy code for steering choice - this is why I'm suss about that gameport.

    Any problems offline?

    Yeah, Uwe, does this happen while another player is joining?   if so,
that is something that has been with ISI sims from the beginning.  One
thing to do is FREEZE your wheel/pedals just as you feel it begin.  I got
so that I could ride these out fairly well.   You can almost anticipate
them and just as the screen pauses, stop everything, don't let off the gas,
just hold everything for that brief moment, then you should be able to at
least stay on the road.
   I wonder if using the latest drivers with the 4800 is such a good idea.  
Those cards seemed to be happiest with late 4x.xx drivers I thought.
I was under the impression that most of the later releases of drivers were
targeted at the GPU era cards...5900 etc.  
   If the skipping happens just randomly, then I'm not familiar with that.  
Good luck

The same rig runs all other sims fine online (including LFS, which
uses the DX routines I think), so I'd be very reluctant to update or
change any of the components just to "play around" and see if the
problem persists or not. If you mean "virus and worm incompatible" by
"well out of date", well, I'd rather stay out of date then ;-)

Cheers & thanks for your reply,

it's not the joinlag bug, it's a regular "jittering" when racing
online. It's hard to describe, but very irritating when taking a
corner on the limit. The car will accelerate randomly for bit (revs
will jump audibly), the lateral position on the car might change, the
viewing angle might flip to the right or to the left and then flip back,
and it happens at nearly regular intervals of five to ten seconds when
racing online, no matter if there are six*** people racing or two or
three.

It looks like a warping problem, only that it's my car that's warping,
not the others 8-P

The problem persists during the race, too.

Any ideas what might be causing this?

Cheers & thanks again for your thoughts,

uwe

thanks for your comments. Can somebody direct me to the "official"
tech support forum? The link seems to have disappeared from the
gtr-game.com site, and as win98 is (still :) listed as a supported
platform I'd like to describe my problem to them at the "official"
place, so to speak.

Regards,

uwe

Probably not the same as what your experiencing as I've only been able to
try the demo:), but I also had a strange twitching problem that caused the
entire screen to vibrate. It seems that the steering wheel/x-axis twitching
we always get in Windows game calibration was raising it's ugly head. As
the x-axis twitched it was multiplied by the Look-To-Apex option.  The cure
was to turn the Look-To-Apex option down to 0 (Options/Realism/Look-To-
Apex)

Its there, just well hidden (top left) :)

thanks for your reply. For me, the effect does not happen in offline
mode, it's only visible in online play, so I guess it's something
network related.

All the best,

uwe

Does the NIC share an IRQ with either graphics/sound/USB/gameport?

Cheers!

Unfortunately no solution so far :-(
