And on the PI3, on highest resolution (800x600) with acceptable speed. It was just a syntax error in my installation files. It is minimum as quick as on my old PC from this years.
I also changed in dosbox.cfg memsize to 63 instead of the default 16 what after my impression has a positive influence.
My dosbox.bat is this

@echo off
:menu
cls
echo.
echo. 
echo.
echo.
echo.
echo DUKE NUKEM 3D
echo.
echo 1 = Play Game
echo 2 = Setup
echo.
echo 3 = Quit
echo.
choice /n /c:123 Make a selection:
if errorlevel ==3 goto leave
if errorlevel ==2 goto setup
if errorlevel ==1 goto play
goto end

:play
DUKE3D.EXE
goto menu

:setup
SETUP.EXE
goto menu

:leave
exit
:end
