N2 frame rate v. ICR2 frame rate

by Otto Mathek » Tue, 29 Dec 1998 04:00:00

I am running N2 50th ed. on a P133 with a Stealth 220 and 48 megs of
RAM.  Finally got it to recognize my Stealth and my mouse, but now
notice that the frame rate is decidedly slower than ICR2.  I am running
the game in DOS and using renddma.bat to start it.  (It crawls if I run
out of WIN95).  ICR2 runs 30+ fps, no problems.

Is this to be expected?  I have all graphics options set to ON.

Unfortunately, Santa did not bring me the Abit BH6, Celeron 300A, etc.
that I wanted!!!
So no GPL for this kid.

TIA

   Probably.  You've got more cars, more detailed cars, more detailed
tracks...  Time to start turning down those graphics options.  Also,
try the 4-bit car graphics option on the command line ("-4"?).

   BTW, when you say you run DOS, you do mean pure DOS, right?  (Boot
Win95, hit F8, select "command prompt only" option.)  That's a lot
faster than a DOS box or Win95's "shutting down to DOS to run this
program" method.

   Bummer.  Maybe you could bargain him down to a P233MMX, which would
help a N2 lot.  And GPL would be tolerable.  :)

    Be aware: by default Win 95 disables the mscdex line in autoexec and you
will have no CD-ROM unless YOU manually add it.  Also, you may need DOS
environment variables for your sound that MAY not be in your autoexec.bat -
they're in your dosstart.bat in c:\Windows.  Compare these 2 files and add
whatever you need to autoexec.bat.

PS I, too, recommend the F8 approach, just MAKE SURE your autoexec is right!

  In your bios there is a setting that can help Rendition frame rates.
Increase your PCI Latency timing
to improve your Verite.   I use 48 but many others have gone much higher.
255 is the max I think.
If you have other pci cards, (sound etc) increasing the pci latency may
degrade them.  experiment to find a happy medium.  and using the -4 command
really helps too.
i.e.  in the renddma.bat put a -4 after the .exe   =  renddma.exe -4(I
think!)

   I'm lucky, I don't need that (everything loaded on the HD and sound
card is old and dumb enough to run on its own :).  If you do, instead
of fiddling with your AUTOEXEC.BAT (and then possibly loading things
in Win95 you don't need), consider making a floppy boot disk with the
proper AUTOEXEC.BAT.  Just pop it in and boot whenever you want to
race.

nothing to be frightened of, and no limit, any fool could get into
a motor car and racing would not exist as a sport." -- Jim Clark

The most elegant (IMO) option is to have Win9x and DOS 6.xx coexist on
the same system. If you still have the old DOS disks, copy all files
to a C:\DOS directory and use expand.exe to uncompress them. Delete
DOS' scandisk.exe and defrag.exe right away, as they will mess up your
system if executed by chance.

Now rename DOS' command.com to command.dos and copy it to the root
directory of the C: drive. Also, create two files called autoexec.dos
and config.dos in the root directory. Those files should contain the
lines for autoexec.bat and config.sys you need in DOS mode.

Next time you start your computer, you can boot to a fully functional
DOS 6.xx by pressing F8 after POST and selecting "previous DOS
version". If you have TweakUI, you can access the old DOS version
directly by pressing F4.

I prefer this over a boot disk for several reasons:

- It boots more quickly.

- I keep losing my boot disks. :)

- All DOS commands are available.

- I can keep my multiple configurations for all kinds of games and
troubleshooting.

- Unlike DOS 7.xx (which will be the OS on your boot disk if you
created it under Win9x), DOS 6.xx has nothing to do with Win9x, so you
can always know what the system is actually doing.

This approach works fine with Win95, 95a and 98, but not with 95b.
Under Win95b, you have to alter one file with a hex editor to allow
"dual boot". But I forgot which one. ;)
