To OS\2 or Not To OS/2
10 messages in this thread
Currently I am using MS-DOS 6.2, and not running in either Windows or OS2. I
am concerned with giving up processor time from 3D Studio to other
applications. If any one has arguments either in favor, or not in favor of
using OS/2 I would be interested in reading them.
Thank you,
Scott
In a not yet optimized setup, a project file that renders in 4 minutes 20
seconds under OS/2 took 3 minutes 53 seconds under DOS. That is with no other
tasks running except the GUI manager and a clock. The theoretical advantage is
that if you can get a background session running, you can send render jobs to
it while modelling in the foreground. Thus while you are pondering your morph
targets, the background session can suck up some of those "free" CPU cycles.

Thank you Larry. Have you run 3D Studio in Windows? Under the Windows
enviroment an application will stall all other programs running until the
process is complete (ie. printing a document or downloading a file). You can't
so much as minimize a group without a beep letting you know you have to wait.
Will I experienced simular delays with OS/2?

OS/2 uses hardware multitasking (aka preemptive multitasking). This is
superior to Windows Apps' cooperative multitasking because you can "jump out"
of a thread at will. IOW, the answer to your question is, "No."
One thing I really like about OS/2 is that I can "suspend" a background
process. Sometimes I have several apps running and things get a little bogged
down. In these cases, I simply "suspend" background execution of a program or
process that is putting the hurt on CPU cycles until I get done what I need to
do. I then set the background process in motion agian and continue about my
business. — Amazing control of system resources. —

PMFJI, but this sounds interesting,
>>I simply "suspend" background execution of a program or process<<
Excuse my ignorance, but exactly how do you suspend and resume programs and
processes in OS/2? (I am using v2.1).
TIA
Peter.

For DOS apps, set the DOS BACKGROUND EXECUTION to OFF, and switch away from the
process. For OS/2 apps, the application will suspend whenever it needs
something that only foreground apps get (keystrokes, usually).

Nope, none of those nasty Windoze-like delays when running under os/2. Windows
is a co-operative multitasker, and it seems like most applications aren't very
co-operative. OS/2 multitasks by timeslicing, with each application being
assigned slices. So the application has no control over when it gives up the
cpu to another task.

I would like to thank Larry, Jame's, and Peter for commenting on the
use of Warp. I did purchase the software and loaded it on my
system. I'm running a Pentium-90 with 32 meg ram, attached is a
Wacom UD-1212 tablet. Good tools with one problem, OS/2 does'nt
recognize the tablet. I understand I need some kind of Pen Software
for OS/2. Please comment on this, but closer to the topic of this
Forum is the need for Autodesk and Wacom to provide support for
running this tablet in absolute mode, and the ability to design
templates simular to those used with AutoCAD. I would like to
progress toward this end.
Thank's everyone,
Scott

If you want OS/2 to understand pen gestures on your Wacom tablet, you'll need a
pen-enabled shell, which is available from IBM. If you want your applications
to understand the tablet, you are probably in the same boat as if you were
under DOS. I just hooked up a Summa tablet to my 3DS system under Warp, and it
worked flawlessly.

To clarify further on Doug's message, try loading the tablet driver in the
"device driver" portion of dos/settings.
