Hi sim racers:
Every once in a while someone asks about running sims on P6 machines.
Here is my impression of siming on my machine.
I'll be posting a similar report about EF2000 in the flight-sim
newsgroup.
My equipment:
Supermicro P6DOF, dual P6 motherboard. Debugged (B step) Orion
chip set. I have one P6 installed.
32 Meg.
Fast wide SCSI.
Matrox 4 Meg. Matrox, not Univbe's, VESA driver.
SoundBlaster 16.
This is a working machine, used for Unix development. After performing
development all week long it likes to relax with racing and flight sims.
Intel has a replacement for my Orion chip set, called the Natoma. New
motherboards are shipping with them. Alex Fernandez posted to this group
that He'll be getting one this week. He said he will be doing some tests
too. So, before he posts his results, I'll tell you what life is like with
my obsolete piece of junk.
I do road racing, almost exclusively. I usually follow the indycar
series through the season by racing on the next road/street course to be
televised. However I feel it is easier to standardize a frame rate test
on an oval track.
The raw number test:
Michigan - no damage, ace with 15 gallons, no qualifying, start in
back, on right side.
Realism - 7% length, no damage, everything else off, constant
weather.
Opponents - Number 31, strength 100%, Drawing 32 forward, 4 back,
heard 2.
Driving Aids - manual everything, no auto spin recovery.
Setup - I drive with a T1, analog everything, linear steering, no
break help, manual shifting. No pace lap.
Graphics - all options on except skidmarks. max framerate 30.
Sound is default.
The raw number:
When the flag drops, and the field is drawn before me, the skidmarks
are visible between the two rows of cars at min 20 FPS (Frame's Per
Second). They seem to start being painted, but are no longer painted
immediately after the start at 22 FPS. The longer the race proceeds,
the more "non-repeatable" things become, so I conclude the test after
a lap or two.
However, if, at 22 FPS, I follow the "train" around the track, the
skid marks come back by turn 3. And they stay back. In order to keep
this "repeatable", I'm resisting the temptation to pass any cars. In
fact I allow the car starting beside me to get ahead, in my view. But
I try to be tucked up close behind the next to the last. You can see
the track "under construction" in the distance.
I don't know what's happening, perhaps as the field spreads out in
front of me,there is less detail to draw.
The skid marks wink in and out, it's quite obvious, at min 23 FPS.
This happens even while the field continues to spread out.
Living with the P6:
Setting the skids to auto has some historical precedence, but it's
not the way I would choose to race.
After running the test, I made the following changes to the graphics
option. Everything on except grandstand detail and dust, which are
auto, and 25 FPS min. Everything else is the same as in the FPS
test.
I then went to Laguna Seca, ace setup, 15 gallons.
It's butter, it's like the movies, the crowd blinked out briefly
after the start, the grand stands are only visible for a second.
by the time I got to the stands at turn 4, I had passed a few cars,
other cars had disappeared down the track, and the crowds sees to be
solid in the stands. Coming out of the corkscrew, I could see the
track "under construction" around turn 6. ICR1, repeat "1", was
never this smooth on my 486/66.
An un-expected benefit, no marbles. I used to run ICR2 on my 486/66,
high rez, most graphics off or auto. Traction was ridiculous. There
is definitely less downforce in ICR2, so there is less traction, but
it is drivable. I do miss standing on it through Laguna's turn 4, 6
and 9. I'm eagar to try different people's setups.
One complaint I remember reading is that the car would spin for no
reason on that fast right bend in the middle of Long Beach's Shoreline
Drive. It feels fine to me.
Should you buy a P6?
This machine works for a living. I don't think I would buy it for racing.
Perhaps the owners of some fast Pentiums will duplicate this test, or come up
with better tests, then we will all know.
If you have any questions, feel free to post, E mail is OK, but I'd rather
everybody who is interested have a chance to listen in.
Am I happy? I'll let you know after Alex tells us what a REAL computer
will do.
Then I tried my home town track, here in Portland, ... OH MY GOD, 131
LINES? You have suffered enough. bye.

You're telling me that after a $1,500+ upgrade I can still only expect 23 FPS in
IndyCarII? Is this some kind of cruel joke?

No...The P Pro is optimized for WinNT. DOS games see no remarkable
improvement. Thanks Intel.

My machine, when I'm not screwing around with it, is used for 3D animation.
modeling, and rendering, and of course NASCAR, and ICR2.
That's me. I just got it yesterday!
I wouldn't call it a piece of junk!
ditto!
Same track. Start at back, no qualifying.
ditto
Opponents - Number 32, strength 100%, Drawing 32 forward, 32 back.
ditto.
ditto except I use a TSW (I love it!) and pace lap turned on. I find that it
stresses the frame rate more and it's the way I run the races.
ditto!
Sound is 8-bit stereo. Strange that mono and stereo had the same test results
for my system.
My results:
The numbers in paranthesis are from my Supermicro P55CMS motherboard with 256kB
PBS cache and 100Mhz Pentium.
With all textures ON, in preseason testing, I get 30 fps!!(18fps). with no
flicker on the skid marks!
The following results represent the max frame rate with no flickering of the
skid marks taken from the start of the pace lap to when the green flag drops.
This is where the biggest hit occurs.
Before race on the pace lap with ALL textures on:
ICR2 (P5-100Mhz) NASCAR
-------- -------------
23fps (11fps) 20fps
All textures ON except asphalt and grass:
28fps (15fps) 25fps
All textures ON except asphalt, grass, wall, grandstand, and objects
30fps (18fps) 30fps
I found Laguna to be slightly smoother than Michigan
I would wait a couple of months or three for them to work out the bugs in the
BIOS (It's an AMI BIOS Rev. 0.1!!!???) I have a couple of problems with it but
nothing major. If anyone has any questions on the motherboard or BIOS, just
email me.
I'm happy. I think that 23-28fps is pretty good improvement but I don't know if
it's worth shelling out that extra dough for games only.

Let's not forget that most of these systems are using a 33 Mhz Bus no
matter how fast the CPU is. There comes a point of dimishing returns when
the CPU is faster, but everything else is just as slow.

True enough. The next quantum leaps are going to come from something
like S-DRAM which is expected to allow motherboard speeds up to
75/80Mhz, or else the widespread implementation of PCI2.1 or higher,
which will allow PCI access at 66Mhz instead of the current 33Mhz.
There comes a point when an EVEN faster cpu just doesn't do very much
more.
Cheers!

because they designeed it for 32bit programs and it from what I
have read in PC magazine it runs 16bit programs (icr2, nascar,
etc.) slower than normal pentiums. Correct me if I am wrong but
from every thing I have read a PPro at 200Mhz will run icr2
slower than a 166 Pent.

You are wrong.

Pemtium Pro is afflicted by unstable chipset and is also very sensitive
to the way it is configured. Without a carefully controlled test, it is
impossible to draw any comparative benchmarks.
Bottom line is a PPro is FAR too expensive just now, and NO-ONE should
buy one only for ICR2/GP2/NASCAR. If you want to play sims, fire into a
P166/P200 (although P133 is best value), if you are looking at WinNT and
also enjoy sims, THEN it's worthwhile looking at a PPro.
Cheers!
John

Forget the Intel P200. If you want fast, the Cyrix P200 KICKS IT'S ASS.
Winmarks over 100. I know Winmarks don't matter in DOS, but they are
the first ones to have machine to do this.
75 Mhz cpu bus...FAST. Check the Mags for more info.

We do not use the BIOS to determine whether the processor is a Pentium. We
use the CPUID instruction to determine whether the processor is a Pentium.
I don't know if this works with a Cyrix chip or not.

I have a 686 166, how would I be able to tell if I'm getting the
optimixed code or not? I've always used the -h option when running the
sim, so I don't know if it would anyway. I know that Win95 ids the
chip as a 486, microsoft says thats because the os was written before
the specs on the 6x86 ( M1) were recieved. ( the NexGen 586 comes up
as a 386 ). So far the only program i've had correctly id it is ZD
labs Winbech, Norton Utilities tells me i got a 300 MHz 486 :-).
Is there a way to trick icr into using the optimized code anyway, or
is it all internal?
The following is an update after some fiddling around with the BIOS
settings and the 440FX chip set registers.
Here are my preliminary test results:
My equipment:
Supermicro P6SNF, single P6 motherboard. Natoma (440FX) chip set which
supports concurrent PCI!
128Meg. RAM (DOS only sees 64MB)
Matrox Millenium 4 Meg. Matrox, not Univbe's, VESA driver. BIOS v2.0
Tropez Plus
The conditions for testing are:
Note that I'm using NASCAR Racing for the Millenium version.
Michigan - no qualifying, start in back, on right side.
Opponents - Number MAX (31 for ICR2, and 38 for NASCAR Racing,
Drawing ALL opponents forward and back, (back doesn't matter
since I tested being able to see all opponents in front of me),
heard 3.
The whole test consisted of just the pace lap since that's the only
time you'll ever see all the cars drawn ahead of you which stresses the
maximum load on the computer.
Graphics - ALL textures on except skidmarks set to auto. Using min
and max frame rate at the same setting, I run the entire pace lap and
adjust the min and max frame rate setting until the skid marks DON'T
flicker at ALL. This final frame rate setting is the minimum that the
computer will run. Of course it will run faster frame rates once the cars
start to spread out during the length of the race.
Sound is 8-bit stereo. Strange that mono and stereo had the same
test results for my system.
My results:
The numbers in parenthesis( ) are from my Supermicro P55CMS motherboard
with 256kB PBS cache and 100Mhz Pentium.
With all textures ON, in preseason testing, I get 30 fps!!(18fps). with no
flicker on the skid marks!
The following results represent the max frame rate with no flickering of
the skid marks taken from the start of the pace lap to when the green flag
drops. This is where the biggest hit occurs.
Before race on the pace lap with ALL textures on:
ICR2 (P5-100Mhz) NASCAR
-------- -------------
23fps (11fps) 20fps
All textures ON except asphalt and grass:
28fps (15fps) 25fps
All textures ON except asphalt, grass, wall, grandstand, and objects
30fps (18fps) 30fps
The only thing new that I add to this is that using a utility written by
John Hinkley that enables PCI write posting, banked VGA Write Combining and
SVGA linear frame buffer Write Combining in the 440FX and Orion chip sets,
I get a big improvement in frame rates for NASCAR racing, no improvement
for ICR2. Anyway, with the above options enabled, I get 27 fps!!, with no
flickering of the skid marks at all. Keep in mind that this is for the
Matrox Millenium version of NASCAR racing. I'll load up the plain version
and do the same test to see if there is a difference.
Feel free to email me with any questions. By the way, I don't post this to
brag about my system. It's for those that are single and don't have
anything else to do with their money(assuming they have plenty of it) and
want to run these sims as fast as possible.
