Works fine in 640 only... For 1024 or 800 I DO indeed have to limit
texture memory to 2 MB.

Here's a great site for reviews and reference  > http://www.combatsim.com/
although I'm not into combat sims, I found this site when looking for
information about PDPI L4 digital game card. You will have to look unders
"hardware" "controller" for the L4 and under "sound cards" for the Montego.

This fixed the GPL texture problem with my new Voodoo 3 3000.
Thank you Graeme and whoever discovered this
I'm now enjoying 1027x768 with all detail on - mmm hmm !

Hi,
Could you please, please, tell me what other hardware you are using and your
framerate at the start with a full field, from the back row, all details,
mirrors, 1027x768,***pit view, at Monaco?   And with number of sounds set at
4?

Thanks,
Tom

thanks for the informative post, very interesting stuff. GPL is
certainly reason enought to upgrade any system, IMO.

But you piqued my curiosity with this:

why's that?

I will say this- I hate driving in general, and try not to much.
people on the road drive me crazy. But I love racing sims, and
particularly online GPL. strange contradiction, I think.

Will this do anything for a v2 SLI setup?

Hi !

I have the a jumpy online performance (Celeron at 450MHz, ABit BH-6 mb,
96MB RAM, Voodoo2, SB 16) and use PDPI L4 gamecard. This card's driver uses
Poll with interrupts by default. Do you have any idea how to fix this or
some workaround ? My online performance was ok, when I had the same spec,
but PII 266 and Intel's LX motherboard with onboard Yamaha OPL-SA2 sound
card.

Thanks,
Tadej Krevh

If you're using the L4 in DirectInput mode then this card uses an
entirely
different method of reading the joystick than how the normal gameport
works.
The card itself does all the capacitor reading, at a very high rate, and
it
does all kinds of fancy smoothing to the results to produce a very
stable
joystick position value. Then when software such as GPL wants to read
the
joystick position, the card transfers that info instantly. Thus freeing
up
the CPU from all that time just sitting around doing nothing while
waiting
for the joystick capacitors. There is thus no problem with other
devices'
interrupts. In fact, I don't even recall seeing the option for polling
with
interrupts in the Joystick control panel applet when I had my L4
installed.
But if you use the generic joystick setting in GPL then the L4
automatically
switches back to behaving like a standard joystick port.

I don't know what might be causing your jumpy online performance, but
the
L4 shouldn't be the problem. You've changed enough other items between
system upgrades that almost anything else could be the cause! :)

Grant.

It can't hurt to try...! (well, maybe it can, but who knows)

Seriously though, don't expect anything to work and if you've already
got good performance don't bother.

To avoid problems with the L4 make sure you do not use "mini drivers". Make sure you set your controller to use only the PDPI devices (prefixed with (L4)), especially in GPL. Make sure you have the contoller panel set to use the PDPI game port. I use a Nascar Pro wheel with split pedals and had to cutomize the Win98 registry settings to get the contol panel to recognize the right half of the steering wheel. (left turns only was a problem). I use a procedure that Greg Renner wrote up in the HMRC NG. Unfortunately the tech support at PDPI are not up on sim racing application or if they are they are reluctant to share this information. If you want these instructions please email me and let me know which format is best for you.
