hey guys... i got a quick question.... I just installed Privateer 2 on my P4 3gig using dosbox... I've sped up dosbox so the game runs well and fast without exhausting my processor (about 15000 to 20000 cycles). Everything runs perfectly except when I get near a planet or a ship. If the planet/ship covers most of the screen, it gets real slow and choppy (like 1 or 2 fps). Does anyone know if I can fix this? maybe a 'video setting' in dosbox or something? I've tried MOST of the settings in dosbox's conf file. I think it's something else. any suggestions would be appreciated.

PC specs:

P4 3.06 GHz with Hyper Threading
512 MB Ram
6800 GT
160GB HD
Sound Blaster Live! Value

I've also tried an AMD 2100+ with the same results

Using:

DosBox 0.63

DosBox conf:

# hwscale -- Extra scaling of window if the output device supports hardware scaling.
# autolock -- Mouse will automatically lock, if you click on the screen.
# sensitiviy -- Mouse sensitivity.
# waitonerror -- Wait before closing the console if dosbox has an error.
# priority -- Priority levels for dosbox: lower,normal,higher,highest.
# Second entry behind the comma is for when dosbox is not focused/minimized.
