Yes, pretty odd, isn't it? Wonder what's the difference between Doom3
and xwing, must be something quite serious.

What dosbox version are you using? Are you sure your cycle settings are optimal??

cycles=7000
cycleup=6000
cycledown=4000

These are probably not optimal settings. I tried this game with recent CVS and it ran quite well.
Try setting this to
cycles=auto
cycleup=500
cycledown=500
and make sure you are running Dosbox 0.65 and not another version.

I've made the new modifications you recommended. I downloaded 0.65, installed it correctly, and set all values.
The sound stuttering has stopped, but the gameplay is still lagging like hell 🙁 Any other recommendations?

Auto does NOT work for dosbox 0.63, that's why you should use
the respectively newest version. The settings Dominus posted
should be a pretty good start there (it's cycles=auto and not
core=auto btw.)

don't bother with 0.63, it's ages old.
Sorry, to rant, but with emulators you really should look if there is a new version out before you even think of asking in the support forum.

Plese do also write a new dosbox.conf. Many settings have changed/new settings were added, that won't show for you unless you let Dosbox write a new one (rename your dosbox.conf to something else, then start Dosbox, and enter "config -writeconf dosbox.conf" (without the ")).

Thank you for the reminder, I haven't thought about a new DosBox version will come out lately.
Yes, I also use the new Dosbox.conf what the program created during the installation. As I said in my modified post, the sound stuttering has been corrected, but the gameplay is still lagging. Anything I should try?

Have you set cycles=auto yet?

Yes, all set! I also set the core to "dynamic", which made the gameplay a bit smoother. The stuttering only happens now if there are many ships around (a group of TIE units or Alliance starfighetrs, a Star Destroyer etc.).

Don't ask how...I think we getting closer. 😀

Try changing output= to overlay or ddraw.

Okay, done. Let's see how it works...

Tried it. The "overlay" couldn't even run the game, the "ddraw" worked, but I see no difference, the stuttering still exists.

Yes it's true, the game seems very demanding when there are explosions on the screen. I can easily pull over 100K cycles in clear space, but with enought explosions the cycles will drop to 20-30K.
My advice for you is to wait a little bit for a new dosbox version. I have a feeling it might run somewhat faster 😉

Well, if nobody has other advices, I will 😀 I would gladly buy a 486 with a Sound Blaster Pro and stuff, but nobody has one 🙁
