hello

privateer 2 has some major slow downs in space when large ships or planets appear on the screen.

increase cycles is not a good solution
when you increase cycles and the large opjects are gone it runs too fast
(changing cycles several times during flight is no fun)
and on the planet surface the game runs to fast as well with high cycles
making it impossible to click anything (game no longer recognises mouse clicks)

with pcem it runs without this issue.

hope smb wants to take a look into this
this is a very old problem.
btw: changing gfx cards and configs make no difference
dosbox versions and forkes make also no difference
same as game versions (tried version 1.6 and 1.7 english and german and 1.6 french)
(and yes i know there is a windows version)

Did you try a fixed amount of cycles with:

1core=normal
2cputype=pentium_slow

PS: It was the right one if I'm not mistaken 😁

Have you tried DOSBox-X with both the fixed cycle setting and a customized vmemdelay value other than 0 (such as -1 or 1000)? PCem by default would generally account for the video memory delay. Wing Commander for DOS has a similar issue, but there was a report that the vmemdelay option does not fully solve it.

thx changing vmemdelay helps
with 1000 it runs much better still not perfect but slow downs are weaker
