Keep in mind several things (from random experience):

In some programs (e.g. my fork of paq8o8), I noticed that OpenWatcom's malloc was much less efficient than DJGPP's.

UPX'd DJGPP .EXEs run much slower under (e.g. XP) NTVDM.

You can usually use WDOSX's "stubit" on OpenWatcom's Win32/PE files to run under DOS natively (since the PE has relocs, which most don't anymore). It will also compress it. However, there is no virtual memory swapping, and you can't undo the changes, so you have to keep a backup of the original. Also, if you shell out from a normal DJGPP (CWSDPMI) program, running a WDOSX program won't work. (Well, probably if you use HDPMI32 instead.)

CWSTUB.EXE is public domain with sources and much smaller than DOS4GW.EXE and less limited in memory and should enable SSE for you automatically, but if your app needs 37 MB of RAM and you only have 32 MB, it will swap the ENTIRE 37 MB out (unlike CWSDPMI, which will only swap the small part needed). However, at least Causeway seems to play nice with DJGPP.

Both WDOSX and CWSTUB have limited support for .DLL files.
