resolution default..... (that options doesn't exist).
try output=overlay

That seemed to help. Thanks!

Hello, I've got a similar problem with the first Discworld game... Every time I change places, the fadeout is very slowly and before it fades to the next screen, it first stays black until something happens or the mouse is moved... when something happens or the mouse is moved at the position where it happens, the screen gets to the picture it should view normally, but only at this specific location... the rest still stays black...
I tried it with output=overlay but nothing changed...

Help pls

Fullscreen only? What OS and what dosbox version?

yes, only in fullscreen... in window mode, the game runs perfect, but it would be much better, if it would do in fullscreen, too

Windows XP & DosBox 0.65

I've noticed this or something similar on various games. Tyrian2K for example. Parts of the screen don't get updated properly after fading, or at least there's a delay before they do, and there's major slowdown during the fade. Only seems to happen with surface output mode for me though. Overlay and ddraw are fine and I'm pretty sure OpenGL is too.
