My rendering times were exactly the same with or without the memory
manager… I didn't force a setup using emm386.exe, however… I don't
belive that QEMM would force expanded memory unless PharLap has a
preference, either… but I will try that next.
OK… I'm back. While I was waiting for my rendering I looked at 3DS's
I&PG…
On page 65, just before 'Important:' I think the manual is a little
misleading… Himem.sys without emm386.exe creates extended memory.
Himem.sys with emm386.exe creates expanded (XMS) memory. Adding a memory
amount to exclude behind emm386.exe returns the memory to extended… at
least, that's the way I understand it (I've been wrong many times before…
and I will be again..<g>). PharLap will not use XMS memory.
I did notice, using the complete compliment of himem.sys and emm386.exe to
create extended memory that I had an improvement of .86 percent in
rendering times (yes, that's correct… less than one percent). It may be
that QEMM will do better (I don't have it here…)… But I can't see
50-60% on this machine… SVGA, 486/33, 16M of memory… total clone.
There has to be a difference in the way that Autodesk has their CMOS's
setup…
