Will adding a second CPU help my simracing rig?

By a silly mistake I bought a dual CPU board and just put in one CPU. My
intensions was to put in the second CPU when I needed more juice and the CPU
price had gotten down. It was a mistake because you have to use identical
CPU's, same speed and same stepping, and it's off course impossible to find
a CPU that matches the one I have now.
But, will GPL, F1 2002 or any other sim run smother or with more FPS if I
trow away my P3 800 and put in two P3 1GHz? I have heard stories about some
games are not able to run on a dual CPU system. Any truth in that? OS is Win
XP Pro.

Your OS is fine - but games are generally not SMP ( i.e more than one
processor ) enabled.

I still think it would be a good idea ( graphics on one cpu - everything
else on t'other)

However - you may notice a slight improvement in performance as one CPU can
handle the OS background, and one cpu can be entirely dedicated to the game.

The improvement will be, however, marginal at best.

Best option is to sell the dual motherboard  ( make great 3d workstations
for rendering etc )  and get a faster single processor athlon :D

Unfortunately as far as I know no Race sims supports SMP (dual processors)
GamesQusing the Quake 2 or 3 engine do and I don't know of many else.
Therefore it's great if you play Medal of Honor of Jedi Outcast etc put is
of absolutley no use in racing games. Best use for the dual processor rig is
to host multiplayer games ie one processor for the games and the other for
the OS.

So the be all and end all if you are a race sim fan is spend your dosh on
faster cpu not more of them. This is a shame but that's the way it is.

Ah, but you see, GPL does indeed support SMP, at least to a certain
extent, can't remember the particulars though, so if GPL is all Jone is
interested in....:-)

GPL, N4, and N2002 all support multi-processor under a multi-processor OS, like NT/2000/XP.  Sorry I
can't tell you anything about the other games...of course the answer to your question also depends
on your video card as well...

GPL, N4 and N2k2 all support SMP I've been informed from a reliable source.

GPL my only waiste of time right now but I was hoping to be able to get more
time to waist.
So Papyrus made sure GPL was compatible with NT4 when it was released? Most
programmers could not care less if their software was compatible with
NT/2000/XP until about a year ago. :)
Quite impressive. Now why do these wonderful guys spend all their time on
NASCAR!!!!!

As others have pointed out, N2 and N2002 also support SMP of course, as
for GPL being NT4 compatible.....no idea how that came about, but DX was
in it's infancy at the time and NT4 supports DX3....something like that
perhaps

And I agree, they should be making an AussieV8 sim rather than this
Nascar stuff

Anyone tried NR2002/GPL on a dual CPU setup? Any comparisons between single
and dual CPU setups.

I doubt if you'll see any real difference between a dual CPU and a
single CPU setup.  If you do, the difference won't be worth the extra
coost of the SMP box.

If the titles are setup to take advantage of a dual CPU set up there should
be a noticable differance. Now in titles not set up for it then I would
agree with you.

Here is what Randy Cassidy had to say about it a few years ago:

"Actually, GPL _was_ specifically designed to take advantage of a
multi-processor system (well, a two-pocessor system, anyway).  There
were
one or two small programming glitches in 1.0 that caused problems on a
multi-processor system, but those were fixed in version 1.1.

Randy"

I quick search of this newsgroup in Google.com of "dual CPU and GPL"
go me lots of reading:

I would suggest doing that. I think the improvement would relate to
about 5 to 10% increase in overall GPL performance. Not really worth
the cost of another CPU, unless you can get one really cheap. I have
found that some computers do not need the CPUs to be matched in the
stepping, and some do.

I'll give it a try.

I'm more interested in NR2002 than GPL and I would think that the newer
title would do a better job of taking advantage of a dual CPU

Got to have something to play with now don't we? If we only used what we
needed whats the point of living :)

I'll have to give that a whirl on my smp system. Are ther any setting you
need to change to enable smp in GPL?
I don't if it'll be of much use in GPL as if maxes out af 36fps even on
quite old systems now, N2K2 could benefit though.
