os2
Generally speaking, if you are doing paging while running 3ds, running under
os/2 will be faster than running under dos. Os/2 will handle the paging, and
can do it faster than the PharLap dos extender in 3ds.
As long as I didn't have other tasks running at the same time, I generally
found that running under os/2 added at most about 10% to the rendering time
over dos.
Background sessions renders are a bit faster than foreground sessions due to
the use of the null driver – nothing is ever drawn to the screen.
Please remember the timings I gave in that file were for os2 ver 2.1. The Warp
version of os/2 includes settings for dos session priorities. By adjusting the
priority settings, you may be able to get a foreground and a background session
running smoothly (being able to render in both) without a big performance hit.
